Vess R2600 OVERVIEW
All PROMISE Vess R2600 and Vess J2600 2000 models support use of 6 Gb/s SAS and SATA disks.
The Vess 2600 controllers feature high speed 8 Gb/s Fibre Channel, or 10 Gb/s iSCSI host connectivity and 1 Gb/s iSCSI host connectivity.
PERFORMANCE
The PROMISE Vess R2600 is built using a 64bit 6-core processor per RAID controller, and support for 6 Gb/s SAS and SATA hard disk drives and solid state drives. Dual active-active controller modules with cache mirroring over a PCIe Gen 2 link allow for redundant data paths to ensure data availability while dual power supply/cooling units minimize downtime and any disruption to business continuity.
VERSATILITY
Support for unified SAN and NAS storage is a new feature of Release 2.0. The new NAS mode provides additional flexibility and better storage utilization for the mix of block-based and file-based applications that typify modern enterprise networks.
SERVICE AND SUPPORT
Every Vess R2600 subsystem is backed by the PROMISE Three-Year limited warranty with English language telephone and e-mail support. In addition to our industry leading warranty, PROMISE offers extended warranty and on-site parts replacement options with service levels with response times as low four hours. 24-hour, 7-day technical support services are available for additional purchase in some regions.
NOTABLE FEATURES IN THE VESS R2600
These features were introduced in Release 1.0, but mentioned here for users who are new to the Vess R-Series.
PERFECTREBUILD™
The PerfectRebuild ™ feature is an innovative approach to rebuilding a RAID array in order to significantly reduce the amount of time needed for completion. This frees up CPU resources more quickly to be available for I/O and other demands. PerfectRebuild ™ ignores any portion of the logical drive where no write changes have occurred, focusing only on the parts that have changed. The conventional approach has been to rebuild the entire logical drive, even sections with no write changes. This reduction in the total time needed for a rebuild is especially significant for very large drives.
ADVANCED BATTERY FLASH BACKUP
Use the optional Backup Battery Unit (BBU) and Flash modules for maximum data protection in the event of power loss. High performance RAID arrays operating in write-back mode present a write loss risk in the event of a power loss. Since data is considered committed as soon as the controller has received it in cache memory, it will be lost if power is interrupted. The conventional solution is to use a BBU to maintain the RAID cache for 72 hours. A better solution is to use power from the BBU to write the content of the RAID controller write cache to non-volatile flash memory in order to extend the period of cache protection beyond the standard 72 hours provided by a typical BBU.
ONLINE LUN CLONE
This is an improvement upon the previous LUN Clone which required the LUN to be taken offline during the duration of the process. The Online LUN Clone feature creates a copy of a LUN without stopping I/O on the source LUN. All data on the source LUN is copied and synchronized in a background operation.
ARCHITECTURAL DESCRIPTION
The Vess R2600 subsystems are suitable for Direct Attached Storage (DAS), Storage Area Network (SAN), and Expanded Storage with the Vess J2600.

NAS SHARED DISK FILE SYSTEM
Release 2 of the Vess R2000 Series incorporates principles of unified storage into its core operation in order to simplify and streamline administration of storage resources and provide greater flexibility to administrators. The Vess R2000 supports file-based NAS and block-based SAN to allow users and applications to access data consolidated on a single device. The tasks of planning, setup and configuration of a NAS environment differ from the same tasks for a SAN. It is recommended that administrators who intend to use the Vess 2000 NAS function read the chapter dedicated to NAS function, “NAS Function and Management” on page 250 before setting up NAS and SAN resources.

MAKING SERIAL CABLE CONNECTIONS
Serial communication enables the terminal emulation application on your host PC or server to access the Vess Command Line Interface (CLI) to set up a network connection. The Vess R2000 Series package includes one RJ11-to-DB9 serial data cable for each controller.
To set up a serial cable connection:
- Attach the RJ-11 end of the serial data cable to the RJ-11 serial connector on one of the RAID controllers.
- Attach the DB9 end of the serial data cable to a serial port on the host PC or server.
Serial port connection
Use the RJ-11 serial port on the controller module to establish the serial communication link. The Vess R2600 is shipped with an RJ-11 to DB9 adapter to be used for this purpose.
CONNECTING THE POWER
To power on the Vess R2600 and any connected Vess J2600 system, follow these steps:
- Connect the power insert for all power supplies on all units.
- Plug in the power cables on all power cords to a suitable grounded power source.
- To turn on the power to the Vess J2600 or Vess R2600 units, press the power button on the front of the left handle of the Vess R2600 devices. See "Front left view of Vess R2600" below for an illustration of the power button. The Vess R2600 features an automatic JBOD detect and power on sequence mechanism so that all connected Vess J2600 expansion units are powered on in the correct sequence. This feature will first power on the Vess J2600s and then the Vess R2600 units in the correct sequence automatically.
After the powering on the Vess R2600 and Vess J2600 units, check the LEDs to monitor the devices.

Disk Carrier LEDs - front of every carrier
The Vess R2600 spins up the disk drives sequentially to equalize power draw during start-up. After a few moments:
• The Power/Activity LED displays blue when a physical drive is present.
- The Drive Status LED displays green when the physical drive is configured as a member of a disk array or as a spare. When the physical drive is not configured, the LED is dark.
In the table below:
• Steady means the LED is on.
- Blinking means a regular on/off pattern.
- Flashing means intermittent and irregular on/off pattern.
DRIVE STATUS LED BEHAVIOR AFTER BOOT UP
| State | Power/Activity Drive Status | |
| Dark | No drive in carrier Drive is not configured | |
| Steady Blue | Drive in carrier – | |
| Flashing Blue | Activity on drive – | |
| Steady Green – | Drive is configured | |
| Blinking Green – | Locator feature | |
| Amber – | Drive is rebuilding | |
| Red – | Drive error of failure | |
* Configured means the physical drive either belongs to an array or it is assigned as a spare drive.
REAR PANEL PSU & COOLING UNIT LEDs

The controller LEDs on the FC and iSCSI controllers are the same except those that indicate network function.
CONTROLLER LED BEHAVIOR
When boot-up is finished and the Vess R2000 subsystem is functioning normally, the Controller status LED displays green continuously; the Management port LEDs display green or flash depending on your network connection; the FC, iSCSI, and SAS Expansion LEDs display green or flash during port activity.
| LED Description | |
| SAS Expansion | Lights green when connected, flashes green when active. |
| Controller Status | This displays the current operational status of the controller. A steady (unblinking) green light indicates the controller is operational. |
| Dirty Cache | Blinks amber if cache is dirty, meaning that the controller memory cache contains data, otherwise this is dark. |
| USB | A steady green light indicates a valid USB connection, this is dark when not connected (no device attached). |
| 1G iSCSI(2 above each port) | Left LED lights green when connected, flashes green when active, dark if not connected. Right LED indicates connection speed, green is 100 Mbps, amber is 1000 Mbps. |
| 10G BASE-T iSCSI(Vess R2600ti)Link/Act and Speed | Two LEDs are located above each port. The left LED lights GREEN when connected, flashes GREEN when there is activity on the port and remains dark no connection has been established. The LED on the right of each port indicates connection speed, GREEN is 10000 Mbps, AMBER is 1000 Mbps, |
| 10G SFP+ iSCSI(Vess R2600xi)Link/Act and Speed | Two LEDs are located above each port. The left LED lights GREEN when connected, flashes GREEN when there is activity on the port and remains dark no connection has been established. The LED on the right of each port indicates connection speed, GREEN is 10000 Mbps, AMBER is 1000 Mbps, |
| FC ports*** | A single LED above each port. Indicates port speed and status with blink and color pattern. See “Fibre Channel port LED behavior (Vess R2600fi controller)” on page 22 for complete description. |
* Vess R2600ti controller has two 10G iSCSI ports.
** Vess 2600xi controller has two 10G SFP+ iSCSI ports for Fibre Optic cabling
*** Vess R2600fi controller has two Fibre Channel ports.
Note
Note that the 10G port speed LED indicator is different than the 1G ports, a GREEN speed LED is the fastest speed on the 10G port, in contrast to the 1G iSCSI I/O ports where GREEN is the slowest speed. AMBER indicates 1000 Mbps on both port types.
SYSTEM SETUP
Now that the Vess R2000 subsystem is installed and connected, it is time to continue with setting up the storage arrays and perform other administration functions. You have a choice of user interfaces for management and administration of the Vess R2000. The administrator can choose to use WebPAM PROe, a web-based graphical user interface (GUI), or use the command line interfaces, or CLI. These are both described in detail in separate chapters.
This chapter covers the following topics:
• "Setting-up the Serial Connection" on page 67
- "About IP Addresses" on page 68
- "Setting-up with the CLI" on page 72
- "Setting up with WebPAM PROe" on page 82
SETTING-UP THE SERIAL CONNECTION

ABOUT IP ADDRESSES
- "Default IP Addresses" on page 68
- "Choosing DHCP or a Static IP Address" on page 69
- "Accessing the MAC Address in the CLI" on page 70
- “Accessing the MAC Address in the CLU” on page 71
Choosing the appropriate IP addresses is essential to manage your Vess R2000 subsystem over a network. You must change the IP addresses of the subsystems as required for your environment.
DEFAULT IP ADDRESSES
The default virtual management port IP addresses are set to:
- IPv4 - 10.0.0.1
- IPv6 - 2001::1
The virtual management port IP address works with either RAID controller, enabling you to access a dual-controller Vess R2000 over your network using a single IP address.
The default physical management port IP addresses are set to:
• Controller 1, IPv4 – 10.0.0.2
• Controller 1, IPv6 – 2001::2
• Controller 2, IPv4 – 10.0.0.3
• Controller 2, IPv6 – 2001::3
The physical management port IP address works with only one RAID controller. The port is used for management of the subsystem and when a controller is in maintenance mode. See “Maintenance Mode” on page 627.
CHOOSING DHCP OR A STATIC IP ADDRESS
When you setup your Vess R2000, you have the option of:
- Enabling DHCP and letting your DHCP server assign the IP address to the Vess R2000's virtual management port.
- Specifying a static IP address for the Vess R2000's virtual management port.
If you choose to enable DHCP, have your Network Administrator dedicate an IP address for the Vess R2000, linked to the Vess R2000's MAC address. This action prevents the DHCP server from assigning a new IP address when the Vess R2000 restarts, with the result that users can no longer log in.
ACCESSING THE MAC ADDRESS IN THE CLI
To access the MAC address in the CLI:
At the command prompt, type net -a list -v and press Enter.
The following information displays:
administrator@cli> net -a list -v

-
Click the Confirm button.
INITIALIZATION
Technically speaking, Initialization is a foreground activity, as you cannot access a logical drive while it is initiating.
Initialization is normally done to logical drives after they are created from a disk array. Initialization sets all data bits in the logical drive to zero. The action is useful because there may be residual data on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended whenever you create a logical drive. See “Initializing a Logical Drive” on page 207.
MAKING INITIALIZATION SETTINGS
To make initialization settings:
- Click the Administration tab.
- Click the Background Activities icon.
-
Click the Settings button.
-

-
High – More system resources to Initialization, fewer to data read/write operations.
-
Click the Confirm button.
REBUILD
When you rebuild a disk array, you are actually rebuilding the data on one physical drive.
- When a physical drive in a disk array fails and a spare drive of adequate capacity is available, the disk array begins to rebuild automatically using the spare drive.
- If there is no spare drive of adequate capacity, but the Auto Rebuild function is ENABLED, the disk array begins to rebuild automatically as soon as you remove the failed physical drive and install an unconfigured physical drive in the same slot. See “Making Rebuild Settings” below.
- If there is no spare drive of adequate capacity and the Auto Rebuild function is DISABLED, you must replace the failed drive with an unconfigured physical drive, then perform a Manual Rebuild.
See "Rebuilding a Disk Array" on page 196 and "Spare Drives" on page 581.
Also see "Disk Array Degraded / Logical Drive Critical" on page 633 and "Disk Array Offline / Logical Drive Offline" on page 634.

-
Check the Enable Auto Rebuild box to enable Auto Rebuild (rebuilds when you swap out the failed drive with a new one).
-
Click the Confirm button.
MIGRATION
The term "Migration" means either or both of the following:
- Change the RAID level of a logical drive.
- Expand the storage capacity of a logical drive.
See “Migrating a Logical Drive’s RAID Level” on page 209 and “RAID Level Migration” on page 570.

-
Click the Confirm button.
PDM
Predictive Data Migration (PDM) is the migration of data from the suspect physical drive to a spare drive, similar to rebuilding a logical drive. But unlike Rebuilding, PDM constantly monitors your physical drives and automatically copies your data to a spare drive before the physical drive fails and your logical drive goes Critical.
See "Running PDM on a Disk Array" on page 195 and "PDM" on page 551.

DISK ARRAY OPERATIONAL STATUS
- OK – This is the normal state of a logical drive. When a logical drive is Functional, it is ready for immediate use. For RAID Levels other than RAID 0 (Striping), the logical drive has full redundancy.
- Synchronizing – This condition is temporary. Synchronizing is a maintenance function that verifies the integrity of data and redundancy in the logical drive. When a logical drive is Synchronizing, it functions and your data is available. However, access is slower due to the synchronizing operation.
- Critical/Degraded – This condition arises as the result of a physical drive failure. A degraded logical drive still functions and your data is still available. However, the logical drive has lost redundancy (fault tolerance). You must determine the cause of the problem and correct it.
- Rebuilding – This condition is temporary. When a physical drive has been replaced, the logical drive automatically begins rebuilding in order to restore redundancy (fault tolerance). When a logical drive is rebuilding, it functions and your data is available. However, access is slower due to the rebuilding operation.
- Transport Ready – After you perform a successful Prepare for Transport operation, this can means you can remove the physical drives of this disk array and move them to another enclosure or different drive slots. After you relocate the physical drives, the disk array status shows OK.

CREATING A LUN CLONE
A LUN clone is an exact copy of the original LUN or logical drive, including all the data it contains, at one point in time. Use a LUN clone as a backup or to copy a LUN from one system to another.
A LUN clone has the same capacity, stripe size, read and write policies as the original LUN. However, the LUN clone can be a different RAID level. The choice of RAID levels depends on the disk array. And if you have multiple disk arrays, you can create the LUN clone on a different disk array than the original LUN.
This action requires Super User or Power User privileges.
LUN CLONE OPTIONS
The Vess R2000 includes a new LUN Clone option, the Online LUN Clone. This is used to a LUN without stopping I/O on the source LUN. All data on the source LUN is copied and synchronized in a background operation. The cloning process runs in the background and continues until it is explicitly stopped by the administrator. This is in contrast to the Offline LUN Clone which requires that the source LUN go offline during the process.
First decide if the LUN is cloned to either a Disk Array or another Logical Drive, then choose the Offline or Online option for the method used.
Important
The action of creating an Offline LUN momentarily takes the original source LUN or logical drive offline, meaning nobody can read or write to it.
To create a LUN clone of a logical drive:
- Click the Storage tab.
- Click the Logical Drive icon.

- For LUN Clone to LD check available Logical Drives in the list for the target LD, and choose Online or Offline for the type of cloning process.
• For Online Clone enter a time in minutes for Mirror Write End Time.
Up to 8 clones of a LUN can be created at a time if there are enough Disk Arrays or LDs available.
- Click the Next button and review your choices.
- Click the Start button to begin the cloning process. You need to Confirm the Lun Clone start in a pop-up menu.
The cloning progress bar displays.
Note the Target Logical Drive ID. Use this number to identify the LUN clone in the Logical Drive list.
If you chose a redundant RAID level, the LUN clone is automatically synchronized after creation.
After the LUN clone is created, you can manage it like any other logical drive. See “Making Logical Drive Settings” on page 205, “Locating a Logical Drive” on page 206, and “Deleting a Logical Drive” on page 204.
For users to access the LUN clone, you must map it to an initiator. See “Managing LUNs” on page 223.

NAS FEATURE OVERVIEW
Release 2 of the Vess R2000 Series incorporates principles of unified storage into its core operation in order to simplify and streamline administration of storage resources. The Vess R2000 supports file-based NAS and block-based SAN to allow users and applications to access data consolidated on a single device.
This new feature is intended to improve overall performance and allow centralized management of NAS and SAN resources, however more careful planning of storage environment will be necessary in order to fully utilize the advantages this system provides. Consideration should be given in particular to how reliability or performance might be improved or reduced for mission-critical and other applications before allocating NAS or SAN resources.
The main characteristics and advantages of the NAS/SAN unified approach are:
- File-based (NAS) and block-based (SAN) access are consolidated in a single storage system that supports fibre channel SAN, iSCSI SAN, and NAS using standard file protocols such as CIFS and
• Storage of file data and block-based I/O (input/output) of enterprise applications function simultaneously. - Overall hardware costs are reduced since both the SAN and NAS operate in a single system.
• Flexibility for virtual server environments - Simplified management
PLANNING CONSIDERATIONS FOR NAS AND SAN SETUP
Before you begin setting up the NAS and SAN functions for the Vess R2000 Series, keep in mind these important issues before laying out cable and beginning configuration of the NAS or SAN. Typically when NAS sharing protocols (CIFS, NFS, AFP) coexist with iSCSI, the throughput for NAS is separated from iSCSI. This is achieved with the physical cable connections, and operational and logical control (portals) over the physical ports. Application servers are generally going to access the iSCSI SAN and NAS client hosts access sharing via a portal created for that purpose. Cabling setup can effect performance in a mixed NAS/SAN network. See “Network Cabling for NAS” on page 254 before planning cabling layout.
NAS configuration includes IP settings, control over physical ports including port aggregation, and portal settings for the physical ports. Normally a single IP address is used for NAS. The NAS portal is configured for a single controller, the Master controller; and it remains unaffected whether the subsystem is operating in Active-Active or Active-Passive Mode, as long as both controllers have identical cable setups. The NAS portal stays the same if a failover occurs. Please read "Create a NAS portal" on page 270 for more information on how to setup portals for the various network scenarios.
NETWORK CABLING FOR NAS
The Vess R2000 Series supports simultaneous NAS and iSCSI SAN function. However there are significant differences that impact the cabling schemes used for the two setups. Make sure you understand the available options for arranging and connecting cabling for NAS and iSCSI SAN operation; AND the implications of the cabling scheme for configuration of the NAS, BEFORE you begin connecting the network. Please read "Cabling and Portal Setting for NAS and iSCSI" on page 272 for details and illustrated example.

NAS CONFIGURATION
To begin NAS configuration, first change the WebPAM PROe display menus used to setup the NAS. Click on the NAS button at the top center of the interface. The display changes to the Dashboard for NAS configuration.
NAS Configuration Dashboard
The Dashboard for NAS configuration is organized and functions in much the same way as the System Dashboard, with links to the most frequently accessed menus in the left hand panel, and an information display in the main display panel that lists current NAS users. The primary configuration and NAS function menu tabs are located near the top of the page.
FILE SYSTEM
The main functions of the File System menus are presented in the following sections:
- "Create a Disk Pool" on page 257
- "Create a Share Disk" on page 261
- "Create a NAS portal" on page 270 (I/O Network Management)
• "Disk Pool Transport" on page 265
The sections listed above provide step-by-step descriptions for setting up basic NAS function in the Vess R2000 Series. In addition, the File System menus also used to:
• Extend an existing Disk Pool
• Create a Home Share disk
- Mount an ISO image
- Create user quotas
- Enable/disable NAS protocols
All these functions are covered in the sections that follow.
CREATE A DISK POOL
The first step to setting up the NAS function for the Vess R2000 Series is to create a Disk Pool. A Disk Pool is simply a group of physical hard drives that are dedicated for use in a NAS configuration. The Disk Pool is used for creation of one or more Share Disk(s) that are made available for users for file-based NAS storage. Users with access privilege can access the Share Disk or Disks through the NAS Portal. Follow the procedure below to create a Disk Pool, then proceed to "Create a Share Disk" and "Create a NAS portal" to read instruction for completing the setup procedure for the NAS function.
To create a Disk Pool:
- Click on the NAS Configuration button at the top of the menu to change the user interface to NAS Configuration.
Disk Pool list (no Disk Pools)
- Click on the File System menu tab, then the Disk Pool menu link.
Create Disk Pool main menu (Choose drives for Disk Pool)
- Click on the Create button, the Create Disk Pool menu displays.
- The Create Disk Pool menu displays a virtual front of the Vess R2000 enclosure. Hard disk drives that are unavailable for use appear colored in light blue shading (see example above). Hard disk drives that are available for the Disk Pool appear with the power LED lighted on and without any shading (HDDs 13 - 16 in the above example).
- Choose the hard drives to use for the Disk Pool being created and click the Next button. A new menu appears. Note that selected hard disk drives appear purple color after selection.
- In the new menu, enter a name for the Disk Pool and select a RAID Level from the pull-down menu. The RAID level options available depend on the number of hard disks in the Disk Pool.
- Click on the Apply button to create the new Disk Pool. The newly created Disk Pool appears listed in the main Disk Pool menu. The amount of time needed for initialization of the Disk Pool depends on its capacity.
Create Disk Pool configuration menu
Note
For best performance, a Disk Pool of 4 - 6 hard disk drives with a RAID 5 configuration is recommended. However the Disk Pool can use more hard disk drives or RAID configuration if the user prefers.
Disk Pool appears listed
Once the Disk Pool is created, you can create a Share Disk with part of or all the available capacity on the Disk Pool. For step-by-step setup instruction to create a Share Disk, please skip ahead to "Create a Share Disk" on page 261.
It is also possible to extend a Disk Pool after it has been created. For instruction on how to extend a NAS Disk Pool, please see the next section, "Extend a Disk Pool".
EXTEND A DISK POOL
A previously created Disk Pool can be extended if there are physical disks available. A Disk Pool extension must use the same RAID type as the Disk Pool that is being added to. Therefore, the same restrictions apply regarding the minimum number of drives needed for the addition. For example, if you are adding to a RAID 5 Disk Pool, you will need to choose at least four physical drives for the extension.
To add capacity to an existing Disk Pool by creating an extension:
- Move the cursor over the Disk Pool you want to extend in the Disk Pool list, and click on the Extend button.
- Choose available physical disks by clicking on them (similar to the Create Disk Pool menu). The disks chosen change color and appear in the list under the virtual device in the menu (same as with Create Disk Pool menu).
- Click the Apply button to add the selected disks to the Disk Pool. The the initialization process begins for the added disks.
CREATE A SHARE DISK
After creating one or more Disk Pools, it is time to setup the Share Disks. The Share Disks function like a shared folder or virtual disk. They can be configured to use part or all of the available capacity on a Disk Pool, using one or more of the following protocols: CIFS, NFS, AFP, FTP and WebDAV. Follow the instructions below to create one or more Share Disks.
The Share Disk menu also allows creation of a Home Share (one per Disk Pool), as well as the Mount ISO Image function. These features are described in later sections. Please read "Create Home Share Disk" on page 264 and "Mount ISO image" on page 269 for more information.
To create a Share Disk:
- Create at least one Disk Pool (see "Create a Disk Pool" on page 257).
- Click on the Share Disk menu link. The Share Disk menu appears listing Share Disks that have already been created.
Share Disk menu
- Click on the Create Share Disk button. A new menu is displayed.
Create Share Disk menu
- Choose the Disk Pool that will be used for the Share Disk from the pull-down menu, enter a name for the Share Disk, enter a value for the Capacity in GB (gigabytes) or TB (terabytes) to use for the Share Disk; or click the option to Use All Available Capacity to use the capacity remaining on the Disk Pool.
- Set the Default Permission for read and write privileges for users of the Share Disk. Note that read and write permissions for any Share Disk can be changed later. To change permission settings for an individual or group, go to the Permission menu under the Account menu tab. To change the permission setting for an entire Share Disk, click on the Share Setting button for the disk you want to change in the Share Disk list.
-
Click to select what protocols will be used for the Share Disk. The available options are Windows (CIFS), Unix/Linux (NFS), Mac (AFP), FTP and WebDAV. Protocols must be universally enabled before they are available for use. By default, they are all enabled. To enable or disable any protocol system-wide for the NAS, use the Protocol menu.
-
You have the option to Enable Encryption for the new Share Disk.
- Click on the Apply button to create the new Share Disk. The newly created Share Disk configuration appears listed in the main Share Disk menu. See example below.
New Share Disk appears in menu
When you have completed creation of the Share Disks, you can then create a portal which includes the IP address used to access the Share Disks on the NAS. Skip ahead to "Create a NAS portal" on page 270 to read a description of how to create a NAS portal.
CREATE HOME SHARE DISK
A single Home Share Disk can be created for the NAS. The Home Share Disk procedure is basically identical to the Create Share Disk procedure described in the previous section.
User folders are available on the Home Share Disk when accessed via CIFS, FTP or AFP.
To create a Home Share Disk, follow these steps:
- Click on the Create Home Share Disk button.
- Choose the Disk Pool that will be used for the Share Disk from the pull-down menu, enter a name for the Share Disk (optional), enter a value for the Capacity in GB (gigabytes) or TB (terabytes) to use for the Share Disk; or click the option to Use All Available Capacity to use the capacity remaining on the Disk Pool.
- Click to select what protocols will be used for the Share Disk. The available options are Windows (CIFS), Mac (AFP), and FTP. Protocols must be universally enabled before they are available for use. By default, they are all enabled. To enable or disable any protocol system-wide for the NAS, use the Protocol menu.
- Click the Apply button to create the Home Share Disk.
Disk Pool Transport
The Vess R2000 supports transport of a Disk Pool. That is, a Disk Pool created on one Vess R2000 enclosure can be removed and installed in another Vess R2000 enclosure, but there is a process that must be completed before the physical drives are removed. This procedure is very similar to the Disk Array Transport described in "Preparing a Disk Array for Transport" on page 196.
Note
Export the NAS settings file to your local computer before transporting, then import and apply the settings in the enclosure that receives the Disk Pool in order to preserve the settings for the Disk Pool.
Before you begin the Transport procedure, first backup (export) the NAS settings so the same settings can be applied to the Disk Pool in the other enclosure. Follow the instructions below.
EXPORT NAS SETTINGS FOR TRANSPORT
To export NAS settings:
- In NAS configuration: Misc and click the Backup/Restore Settings button.
- Select the Export tab and click the Submit button.
- Place the settings .imp file on the local computer.
- Proceed to the Transport procedure.
TRANSPORT DISK POOL
To prepare a Disk Pool for transport, follow these steps:
- In NAS configuration: File System > Disk Pool and click on the Share Disk in the list you want to move.
- Click on the Transport button.
- Click on the Confirm button in the pop-up menu.
A message informs you that the Disk Pool is ready for transport. Now you can safely remove the physical disks and reinsert them into available disk bays on another Vess R2000 enclosure. Once inserted, it will be necessary to Rescan the Disk Pool so it can be used.
RESCAN DISK POOL
After the complete Disk Pool (i.e. all the physical drives of the transported Disk Pool) has been installed on the other Vess R2000 enclosure, it will be detected automatically. In order to begin using it however, one more procedure remains, to Rescan the Disk Pool.
- Go to the Disk Pool list, NAS configuration: File System > Disk Pool.
- Notice there is now a button, Rescan, that appears above the list. Click on the Rescan button. When the Disk Pool has been scanned, a Success message appears. It is now ready for use.
Rescan transported Desk Pool
IMPORT NAS SETTINGS FOR TRANSPORTED DISK POOL
Now that the Disk Pool has been physically installed and rescanned, you can apply the same settings for it from the previous enclosure. To import NAS settings:
- In NAS configuration: Misc and click the Backup/Restore Settings button.
- Click on the Import tab and click Browse to locate the imp settings file.
- Click the Submit button and then the Confirm button. A message appears that the settings have been changed. The Disk Pool should now be functionally the same as it had been in the enclosure it occupied previously.
SET USER QUOTAS
The default settings for users and groups do not place any limit on the amount of disk space available for use. To set a limit on the total amount of disk space allowed for use by a Domain Group, Local Group, Domain User or Local User, use the Quota Setting menu. Quotas are measured in Gigabytes, a value of 0 means there is no quota limit for the user or group.
Quota Setting menu
To set a Quota, follow these steps:
- In NAS Configuration, File System > Quota.
- Click on the Quota Setting button.

MOUNT ISO IMAGE
NAS configuration enables the use of ISO image files that have been previously placed on a Share Disk, including a Home Share Disk. When the ISO image is mounted, it becomes available for users of the Share Disk.
To mount an ISO image, follow these steps:
- Click on the Mount ISO Image button.
- Choose the Share Disk where the ISO file is located from the Source Share Disk pull-down menu.
- Use the ISO Image File menu to locate the ISO file.
-
Click to select what protocols will be used for the Share Disk. The available options are Windows (CIFS), Unix/Linux (NFS), Mac (AFP), FTP and WebDAV. Protocols must be universally enabled before they are available for use. By default, they are all enabled. To enable or disable any protocol system-wide for the NAS, use the Protocol menu.
-
Click the Apply button to mount the ISO image.
CREATE A NAS PORTAL
The final step to configuration of NAS is to create a NAS portal. In order to better understand the configuration options for port and portal configuration, a few different examples of cabling schemes and the configuration of I/O ports used with the cabling arrangement are presented with illustrations. To create a portal for NAS:
- In NAS Configuration, click on the File System menu tab, then the I/O Network Management menu link. The top menu displayed lists any current Portal configurations including the IP address used for the portal.
- Click on the Create Portal button, a new menu appears.
- Configure the NAS portal. The choices include options to create a port trunk or to use individual ports without trunking, configuration of IP settings, and VLAN settings. Please refer to the examples that follow for explanations of these portal settings.
Create Portal menu
WHAT IS A NAS PORTAL?
A portal is the logical point of connection between the Vess R2000 Series and the NAS clients. Portals use an IP address and a TCP port number to identify an IP storage resource. Normally only one portal is created for NAS, though multiple portals can be used for NAS. Many portals might be used for iSCSI operations.
Vess R2000 Series supports both IPv4 and IPv6 addresses.
Portals on Vess R2000 Series supports the following types of port associations:
- Port ID – The number of the Gigabyte Ethernet data port associated with the portal.
- Controller ID - For dual controller subsystems, the Controller ID and Port ID indicate the physical data port associated with the portal.
- VLAN – Virtual Local Area Network. The portal is part of a virtual network, data frames contain a VLAN tag read by switches and routers to indicate what VLAN it belongs in.
- Trunk – An aggregation of two or more Gigabyte Ethernet ports on the same controller. Also known as a link aggregation. This feature combines ports to increase bandwidth.
CABLING AND PORTAL SETTING FOR NAS AND ISCSI
This section uses illustrated examples to demonstrate some cabling schemes that can be used for NAS and iSCSI operation as well as the corresponding port and portal configuration create using the I/O Network Management menu located in the NAS Configuration menus.
As a reminder, the physical ports for data and management are pictured below with data ports numbered. The tables with the examples used in this section refer to the controllers and physical data ports by number.
Management and Data ports on Vess R2600iD
Important
For dual controller systems, the NAS portal always runs through the Master controller regardless of whether the subsystem is Active-Active or Active-Passive. So the portal setting is made on one controller only.
BASIC NETWORK CABLING AND PORT CONFIGURATION FOR NAS AND ISCSI
The first example shows a basic cabling scheme using a single switch or router for all data and management connections. NAS client hosts access storage through IP network via sharing protocols, while application servers access Vess R2000 storage via iSCSI protocol, portal associations are used to keep them separated. See table and Create Portal settings menu example below.

REDUNDANT PORT CONFIGURATION FOR NAS AND ISCSI
Use of redundancy will prevent disconnection in the event of a port failure on a controller or cable failure. For dual controller subsystems, the iSCSI protocol already has Multipath I/O for redundancy and load balancing. However for NAS it is necessary to create a port trunk to achieve this. Further redundancy is created with more advanced cabling and two switches or routers, and with redundant IP settings.
The first method of redundancy using a single switch or router, uses that same basic cabling arrangement as illustrated in the previous example except that two ports on each controller are trunked and assigned a NAS portal. This example is explained in "Table 2: Redundant portal settings" below and illustrated in "Redundancy with port configuration".

ADVANCED REDUNDANCY NETWORK CABLING AND PORT CONFIGURATION
The final example uses two switches or routers to create an additional layer of redundancy for high availability. Using this cabling method, it is necessary to trunk all four ports on each controller.

BACKUP
Backup settings for the NAS are created and configured using the menus described below. Typically the backup relationship is with another Vess R2000 remotely located and managed using these same menus.
• Backup Server Settings
- Replication Backup
- Replication Recovery
- File Backup/Restore
- Share Disk Clone
BACKUP SERVER SETTINGS
The Backup Server Settings is used to designate remote systems that are allowed to backup on the Vess R2000, and configure port settings for the backup via normal or encryption ports. Once the remote IP address is allowed, the remote system, another Vess R2000 for example, can be configured for scheduled backups to this Vess R2000. On the remote Vess R2000, you would use the Replication Backup menu to configure this backup arrangement.
ALLOW IP FOR BACKUP
To add a remote system allowed to backup to the Vess R2000, follow these steps:
- In NAS configuration: Backup > Backup Server Settings
- Click the Create button.
- Type the IP address of the remote system allowed to backup and click the Add button.
- For each system you want to add to the Allow IP list, repeat steps 2 and 3.
- Click the Apply button to create the backup settings.
After the Allow IP list is created for a Share Disk, you can add or remove an IP address allowed for any Share Disk on the list, or remove the Share Disk configuration and all the IP addresses on the associated Allow IP list.
- To add a new IP address to the Allow IP list for a Share Disk backup configuration, click on the Share Disk row in the list, click on the Setting button, for each IP address you want to add, type in the IP address in the space provided and click the Add button. When finished adding IP addresses to the Allow IP list, click on the Apply button.
- To remove an individual IP address from a Share Disk Allow IP list, click on the Share Disk row in the list, click on the Setting button, and the click on the trash can icon for the IP address you want to remove.
- To remove an entire Share Disk backup configuration and all the IP addresses on the Allow IP list, click on the Delete button for the Share Disk backup configuration, then click on the Confirm button that pops up.
BACKUP SERVER PORT SETTINGS
The administrator has the option of using the default port for backup, or specifying the port. The port has an additional option of using encryption for the backup transmissions. Encryption is enabled on the client using the Replication Backup menu (see "Replication Backup" on page 281). Use this menu only if you want to change the default port setting used for backup. Keep in mind that the port change must also be made on the client using the Replication Backup menu.
To change the backup port used for normal or encryption backups:
- In NAS Configuration: Backup > Backup Server Settings
- Click the Port Settings button.
- Click on the Use Default option box to deselect it.
- Type a number in the range 1025 to 65532 for the Encryption Port, and type a different number in the same range for the Normal Port.
- Click the Apply button to change the backup port settings.
REPLICATION BACKUP
Replication refers to the process of copying or mirroring data content on a Share Disk. The Share Disk is recreated entirely on a different NAS. The identical Share Disk uses the same name as well. The policy used to create the replicated Share Disk can be to mirror or copy the Share Disk (see Policy in instructions below).
Keep in mind the following points for a Replication Backup setting.
- Replication Backup Share Disks are made to a remote NAS and must use the same name as the original Share Disk on the source NAS.
- A NAS portal must be configured to create the replicated Share Disk.
- The remote NAS must “allow” the IP address of the Share Disk on the original NAS. See “Allow IP for backup” on page 279.
- Replication Backup policy choices are: Mirror Mode to sync added and changed files, and file deletions are mirrored as well; or Copy Mode to sync added and changed files without deletion of files that were deleted from the source Share Disk.
- Replication Backup can be used for multiple Share Disks on the remote NAS.
- A temporary Share Disk snapshot is created if snapshot is available.
• Differential and compression transmission are supported. - Encryption is supported for transmission.
- Replication Backups can be scheduled.
- Other Replication Backup parameters include connection timeout limit, retry attempts allowed and maximum transfer rate.
Create Replication Backup menu
To create a Replication Backup for a Share Disk, follow these steps:
- In NAS configuration: Backup > Replication Backup
-
Click the Create button, enter configuration settings for the Replication.
-
Enter the IP address of the Remote Backup Server (a separate NAS)
- Choose a Policy for replication: Mirror Mode syncs added and modified files and mirrors file deletion, Copy Mode syncs added and modified files and does NOT delete any files that were deleted on the source Share Disk.
- Optional settings include Encryption (check box to enable) changing the Port on the backup server. To change the default Port number, uncheck the box and type in the port number to use.
- Choose the Portal IP for the NAS from the drop-down menu.
- Choose the Schedule type to use for syncing. Note that the default value Disable means the replication is done manually (see "Run Replication Backup" below).
- Choose the number of Retry Times, the number of times to try again if the connection fails.
- Connection Timeout is the time in seconds allowed for the connection to be idle before disconnecting.
-
Change the Maximum Transfer Rate if you want to limit the rate at which the transfer is allowed to proceed. By default, this is unlimited.
-
Click the Next button to proceed.
The connection will first be validated.
- If the connection to the server is made, choose Share Disks with identical names on both ends of the backup connection, that is, the source and destination Share Disk must have the same name.
- Click the Apply button to create the Replication Backup settings.
RUN REPLICATION BACKUP
To manually run a Replication Backup, follow these steps:
- In NAS configuration: Backup > Replication Backup and click on the Replication Backup setting in the list for the Share Disk you want to backup.
- Click on the Run button.
- You need to confirm to run the backup. Type "confirm" and click on the Confirm button.
REMOVE A REPLICATION BACKUP
To delete a Replication Backup setting, follow these steps:

- You need to confirm to remove the backup. Type "confirm" and click on the Confirm button and the Replication Backup setting is removed.
REPLICATION RECOVERY
After a Replication Backup of a Share Disk is completed on a remote NAS, the backup is available for future recovery. During the recovery, the remote replicated Share Disk is mounted in the same position as the original local Share Disk. When the recovery is completed, the recovered original Share Disk automatically goes back into the normal position and the replication backup Share Disk reverts to backup status.
Keep in mind the following points for Replication Recovery:
- Replication Recovery requires at least one previously replicated Share Disk to replace the local Share Disk. See "Replication Backup" on page 281.
• The remote replicated Share Disk is mounted in the same position the damaged Share Disk occupied.
• Each Share Disk recovery can occur from one replicated Share Disk at a time, even if more than one replicated Share Disks have been created. - When the recovery process is completed, services are automatically switched back to the newly recovered Share Disk which is mounted in the original position.
- During the recovery process, NAS functionality is normal since the remote Share Disk is temporarily active for local NAS users. Service to users of the Share Disk are not affected.
• Differential and compression transmission are supported.
• Whole Share Disk files are synchronized before the switch back to the recovered Share Disk occurs. - Automatic switch back function will delay for up to 24 hours if the Share Disk is busy. After 24 hours if the switch back has not occurred, it will be forced.
To begin the recovery process:
- In NAS configuration: Backup > Replication Recovery and click on the listed Replication Recovery configuration for the Share Disk that has been previously backed up using Replication Backup.
- Click on the Recover button.
- Choose the backup server, and click the Apply button.
FILE BACKUP/RESTORE
The File Backup and Recovery function is similar to the Share Disk Replication Backup and Recovery, except instead of backing up the entire contents of a Share Disk, you choose individual files to backup. Also there is an additional policy mode Version which syncs all file changes in a new folder, effectively saving a new time-stamped version of the file. The Version policy allows restoration of backed up versions of files, selected according to the time created.
Keep in mind the following points for File Backup and Restore:
For File Backup:
• The destination Share Disk can be located on a remote NAS or on the local one.
- Files for backup must all be on the same Share Disk.
- Setup a NAS portal configuration before using File Backup.
- For backup to a remote NAS, the remote NAS must "allow" the IP address of the Share Disk on the original NAS. See "Allow IP for backup" on page 279.
• A temporary Share Disk snapshot is created if snapshot is available.
- A folder on the destination Share Disk named Backup is created for the backed up files.
- Hard link is used for reserving the destination Share Disk space if there are multiple copies.
- Differential and compression transmission is supported.
• File Backups can be scheduled.
- Other File Backup parameters include retry attempts allowed.
For File Restore:
- File Restore settings are dependent upon the file backup task.
- If the destination backup Share Disk is on a remote site, the remote NAS must "allow" the local IP. See "Allow IP for backup" on page 279.
- All restored files on the original Share Disk are placed in a file named Restore, the task name and date version are included in the file path.
- Differential and compression transmission is supported.
To configure File Backup:
- In NAS configuration: Backup > File Backup/Restore and click on the Create button.
Configure these settings:
- Task Name: Enter a task name for the File Backup configuration.

Summary
The array command is the main command for performing advanced configuration and maintenance tasks on disk arrays.
This command is used to list, create, modify, delete, and locate disk arrays. Also to add and delete logical drives.
Note that you cannot mix Hard Disk Drives (HDD) and Solid State Drives (SSD) in the same disk array.
Options
-a
list (Default) Displays a summary of all or a specific or a specified
number of arrays.
add Add/create an array and possibly some logical drives
at the same time.
addId Add/create a logical drive to an array that already
exists.
delld Delete an existing logical drive from an array.
mod Modify settings of an existing array.
del Delete an existing array and all its associated logical drives.
locate Locate an array.
accept Accepts the condition of an incomplete array. There are two
conditions that will cause the array to report as incomplete:
- Missing Drive, i.e. when one or more drives are missing in the array.
- Missing NVRAM Watermark, the NVRAM Watermark of migration
not found on the controller, however the DDF on the array
indicates the migration is in progress.
When the either of the above condition happens, all the logical drives on the
array will become offline.
The user can do an accept to acknowledge the incomplete condition of the array, and try to recover the access to the array and logical drives on the array, in other words, to bring the logical drives online. However, it is a high-risk and non-revertible operation, and it may result in data loss.
Therefore, it is recommended to try to clear the condition first, e.g., to put the missing drives back; or to roam the array back to the original controller and wait until the migration completes.
transport To gracefully make the array and the logical drives on the array
offline to get ready for transport the array to another subsystem.
untransport Cancels the transport action on the array and the logical drives.
Brings the array back online in the original subsystem.
Not supported for HBA products.
online To set all the dead physical drives of array online at a time.

config
Usage
config -a auto
config -a expr [-r y|n] [-c y|n] [-p y|n] [-m y|n] [-s y|n] [-t
Summary
The config command has two options, Automatic (auto) and Express (expr).
Automatic configuration takes all available unconfigured physical drives to create an optimized disk array following a default set of parameters. There are no options.
Express configuration takes your input, creates one or two arrays, and spreads their capacity evenly over all of the logical drives that you specify.
The redundancy option creates redundant logical drives (RAID 1, 10, 1E, 5, 50, 6, or 60).
The capacity option enables optimizes the logical drives for capacity. The performance option optimizes the logical drives for performance.
If you choose all three options, redundancy gets highest priority and capacity gets lowest priority.
Note that you cannot combine HDDs and SSDs in the same disk array. If your system has both type of drives, it will create separate disk array/logical drive sets for each type of physical drive.
Options
-a
auto Automatic configuration with no options. Creates an optimized disk array. One or more logical drives are created automatically.

Allows a user to change their password. A normal (non super user) user will never use the -u option, as they are allowed only to change their password. For any user who wants to change its own password, it will be first prompted for their old password before inputting their new password.
For a super user, the -u option can be used to change the password of other users. When changing the password another management user, the old password is not required.
Maximum password length is 31 characters, no spaces.
Examples

Summary
This command allows the user to start, stop, pause or resume a PDM as well as to check on the progress of a running or paused PDM.
PDM (Predictive Data Migration) is an operation to replace a drive in the disk array, which has a PFA condition, with a destination physical drive. The destination physical drive can be an unconfigured drive, a global spare, or a dedicated spare to this disk array.
During PDM, the data on the PFA drive will be transferred to the destination drive while the IO remains going on. After PDM, the destination drive becomes part of the disk array; the PFA drive will become unconfigured and PFA condition will remain on.
The PFA drive cannot be used for further configuration until the PFA condition is cleared by the user.
To clear the PFA condition of a physical drive, please refer to phydrv command with option -a clear.
Options
-a
list (Default) Displays the current active or paused PDM(s) and their

sync
Usage
sync [-a <action>] [-l <LdId>]
Summary
The sync command is used for background synchronization, the process of enforcing consistency in logical drives. This is an optional replacement for LDI (logical drive initialization).
Background Synchronization starts automatically when a redundant logical drive is created while still allowing I/O to be performed to the logical drive (unlike LDI). If LDI is started then background synchronization will halt and LDI will run.
This command may also be used to allow the user to check the status of background synchronization. Since background synchronization is started automatically and yields automatically there is no need to explicitly start, stop, pause or resume a background synchronization.

Summary
The transit command starts, stops, pauses, and resumes a transition and monitors the progress of a running transition.
Transition is an operation to replace a revertible spare drive currently used in a disk array with an new physical drive, so the reverible spare can be restored to spare drive status. The destination drive can be an unconfigured drive, a non-revertible global spare, or a non-revertible spare dedicated to the array.
During transition, the data on the revertible spare is transferred to the destination drive while the disk array remains online. After transition, the destination drive becomes the part of the array and the revertible spare is a spared drive once again.
Note that the destination drive must be the same media type, HDD or SSD, as the other physical drives in the disk array.

CREATING A LUN CLONE (CLU)
A LUN clone is an exact copy of the original LUN or logical drive, including all the data it contains, at one point in time. Use a LUN clone as a backup or to migrate a LUN from one system to another.
LUN CLONE OPTIONS
The Vess R2000 includes a new LUN Clone option, the Online LUN Clone. This is used to create a copy of a LUN without stopping I/O on the source LUN. All data on the source LUN is copied and synchronized in a background operation. The cloning process runs in the background and continues until it is explicitly stopped by the administrator. This is in contrast to the Offline LUN Clone which requires that the source LUN go offline during the process.
First decide if the LUN is cloned to either a Disk Array or another Logical Drive, then choose the Offline or Online option for the method used.
Important
The action of creating an Offline LUN momentarily takes the original LUN or logical drive offline, meaning nobody can read or write to it.
A LUN clone has the same capacity, stripe size, read and write policies as the original LUN. However, the LUN clone can be a different RAID level. The choice of RAID levels depends on the disk array. And if you have multiple disk arrays, you can create the LUN clone on a different disk array than the original LUN.

PROPERTY DEFINITIONS
Definitions of the properties for which statistical information is reported appears in the list below.
- TimeLastReset – Time in minutes since the system has been running.
- FramesSent – Number of frames sent since last reset.
- FramesReceived – Number of frames received since last reset.
- WordsSent – Number of words sent since last reset.
- WordsReceived – Number of words received since last reset.
- LIPCount – Loop Initialization Primitive Sequence. This primitive sequence applies only to the arbitrated
loop topology. It is transmitted by an L_Port to initialize or re-initialize the loop.
- NOSCount – Not Operational Primitive Sequence. This primitive sequence is used during link initialization between two N_Ports in the point-to-point topology or an N_Port and an F_Port in the fabric topology. NOS is sent to indicate that the transmitting port has detected a link failure or is offline. The expected response to a port sending NOS is the OLS primitive sequence.
- ErrorFrames – FC devices propagate handshake signals back-and-forth requesting and acknowledging each byte transferred. FC transfers occur in one frame of data at a time. In this case, the value reflects the number of frames with errors.
- DumpedFrames – This field specifies the number of frames dumped due to a lack of host buffers.
- LinkFailureCount – Number of times the link has failed. Can be caused by a disconnected link or a bad fiber element.
- LossSyncCount – Number of times a loss of sync has occurred since last reset.
- PrimitiveSeqErrorCount – An ordered set transmitted repeatedly and used to establish and maintain a link. LR, LRR, NOS, and OLS are primitive sequences used to establish an active link in a connection between two N_Ports or an N_Port and an F_Port.
LIP, LPB, and LPE are primitive sequences used in the Arbitrated Loop topology for initializing the loop and enabling or disabling an L_Port.
- InvalidWordSentCount – Number of invalid words sent since last reset.
- InvalidCRCCount – Invalid Cyclical Redundancy Count. Number of frames received with an invalid CRC since last reset.
- InitiatorIOCount – I/O Count on the initiator on the host side.

A failed Cooling Unit on the Vess R2600 or Vess J2600 can be hot swapped if the other cooling unit is functioning properly (indicated by a green Fan Status LED). Follow the instructions below to replace a problem Cooling Unit.
Important
In the event of a Cooling Unit failure, DO NOT remove the failed unit until there is a replacement available and on hand. A single functioning Cooling Unit is adequate for cooling the system as long as the failed Cooling Unit remains in place. Removing the failed unit without replacing it will adversely affect airflow within the enclosure resulting in critical overheating and shutdown of the enclosure.
To remove the Cooling Unit
- Check the Fan Status LED, a red LED indicates the fan has failed and needs to be replaced, an amber LED indicates a problem. See "Cooling Unit LED indicates a problem with the fan" on page 543
- Use a No. 1 Phillips screwdriver to turn each set screw counter-clockwise to loosen them. The screws remain attached to the Cooling Unit so they will not be lost.
- Pull the detached Cooling Unit out of the subsystem enclosure. You can grasp the posts that house the set screws initially to move the unit out.
To insert a new Cooling Unit
- Align the fresh Cooling Unit to be received in the empty cooling unit bay of the subsystem enclosure.
- Slide the Cooling Unit into place until the set screws are able to be reattached to the backplane of the enclosure.
- Turn the set screws to tighten them.
- Check the Fan Status LED on the Cooling Unit to make sure it is green (functioning properly).

REPLACING A CACHE BACKUP BATTERY
The cache backup battery, also called a Battery Backup Unit (BBU) powers the cache to preserve data that has not been written the physical drives. The battery is attached to the top of the Cooling Unit assembly. Each Cooling unit has one battery. An amber or red BBU LED indicates a cache backup battery problem. See "Cooling Unit LED indicates a problem with the fan" on page 543.
To replace a backup battery, swap out the Cooling Unit with the BBU that needs replacement. Follow the instructions in "Replacing a Cooling Unit" on page 542.
Important
DO NOT remove a Cooling Unit unless there is a replacement available and on hand. Removing a single Cooling Unit without replacing it right away will adversely affect airflow within the enclosure resulting in critical overheating and shutdown of the enclosure.
Cooling Unit with Cache Backup Battery (BBU) LED indicating battery failure
Cautions
Try reconditioning the battery before you replace it. See "Reconditioning a Battery" on page 121.
The battery assembly is replaced as a unit. Do not attempt to disconnect the battery by itself.
Installing the wrong replacement battery can result in an explosion.
Dispose of used batteries according to the instructions that accompany the battery.
While the battery is removed, your system is vulnerable to data loss if the power fails while data is being written to the logical drives.
If power service has failed, do not remove the battery if the RAID controller's dirty cache LED is flashing. See "Rear Panel LEDs" on page 21.
REPLACING A RAID CONTROLLER – DUAL CONTROLLERS
The RAID controller monitors and manages the logical drives. When the RAID controller is replaced, all of your logical drive data and configurations remain intact because logical drive information is stored on the physical drives.
Important
Do not replace the RAID controller based on LED colors alone. Only replace the RAID controller when directed to do so by PROMISE Technical Support.
The firmware version and amount of SDRAM must be the same on the replacement RAID controller and the other RAID controller in the subsystem.
To obtain firmware and SDRAM information for an installed RAID controller, in WebPAM PROe, click the Administration button then click the Image Version icon.
Replacement RAID controllers to not come with a BBU. Remove the BBU from the old controller and install it into the new one. See .
Note
On subsystems with dual RAID controllers, you can hot-swap a controller while the subsystem is running.
- Disconnect all attached cables from the RAID controller,
- Fibre Channel cables
- Management port cables
- iSCSI cables

REPLACING A RAID CONTROLLER – SINGLE CONTROLLER
The RAID controller monitors and manages the logical drives. When the RAID controller is replaced, all of your logical drive data and configurations remain intact because logical drive information is stored on the physical drives.
Cautions
The RAID controller is NOT hot-swappable if your Vess R2600 has only one controller. Power-down the Vess R2600 before removing it.
Important
Do not replace the RAID controller based on LED colors alone. Only replace the RAID controller when directed to do so by PROMISE Technical Support. See page 435.
Important
The firmware on the replacement RAID controller must be the same version as the original RAID controller or a later version.

TECHNOLOGY BACKGROUND
This chapter covers the following topics:
- "Disk Arrays" (see below)
• "Logical Drives" on page 552 - "Spare Drives" on page 581
• "RAID Controllers" on page 588 - "iSCSI Management" on page 594
• "Internet Protocols" on page 602
Disk Arrays
Disk array technology includes:
- "Media Patrol"
• "PDM"
MEDIA PATROL
Media Patrol is a routine maintenance procedure that checks the magnetic media on each disk drive. Media Patrol checks all physical drives assigned to disk arrays and spare drives. Media Patrol does not check unconfigured drives.
Media Patrol checks are enabled by default on all disk arrays and spare drives. You can disable Media Patrol in the disk array and spare drive settings, however that action is not recommended.
Unlike Synchronization and Redundancy Check, Media Patrol is concerned with the condition of the media itself, not the data recorded on the media. If Media Patrol encounters a critical error, it triggers PDM, if PDM is enabled on the disk array.
Media Patrol has three status conditions:
- Running – Normal. You can access your logical drives at any time.
- Yield – Temporary pause while a read/write operation takes place.
- Paused – Temporary pause while another background runs. Or a pause initiated by the user.
PDM
Predictive Data Migration (PDM) is the migration of data from the suspect phy-cal drive to a spare drive, similar to rebuilding a logical drive. But unlike Re-building, PDM constantly monitors your physical drives and automatically copies your data to a spare drive before the physical drive fails and your logical drive goes Critical.
The following actions trigger PDM:
• A physical drive with unhealthy status (see below)
• Media Patrol finds a critical error
• You initiate PDM manually
PDM also counts the number of media errors reported by Media Patrol. A disk drive becomes unhealthy when:
• A SMART error is reported
- The bad sector remapping table fills to the specified level.
Because data would be lost if written to a bad sector, when a bad sector is detected, the physical drive creates a map around it. These maps are saved in the bad sector remapping table, which has a capacity of 512 reassigned blocks and 2048 error blocks. See “Making PDM Settings” on page 155 or “Managing Background Activities” on page 144.
You can specify the maximum levels for the reassigned and error blocks in PDM settings. When the table fills to a specified value, PDM triggers a migration of data from the suspect drive (the disk drive with the bad sectors) to a replacement physical drive.
During data migration, you have access to your logical drives but they respond more slowly to read/write tasks because of the additional operation. The time required for data migration depends on the size of the physical drives.
PDM is enabled on all disk arrays by default. You can disable PDM in the disk array settings, however that action is not recommended. See “Running PDM on a Disk Array” on page 195.
LOGICAL DRIVES
Logical drive technology includes:
- "RAID Levels" on page 553
• "RAID Level Migration" on page 570 - "Stripe Size" on page 579
• "Sector Size" on page 579
• "Preferred Controller ID" on page 579 - "Initialization" on page 580
• "Partition and Format" on page 580
RAID LEVELS
RAID (Redundant Array of Independent Disks) allows multiple physical drives to be combined together in a disk array. Then all or a portion of the disk array is formed into a logical drive. The operating system sees the logical drive as a single storage device, and treats it as such.
RAID 0 - STRIPE
When a logical drive is striped, the read and write blocks of data are interleaved between the sectors of multiple physical drives. Performance is increased, since the workload is balanced between drives or “members” that form the logical drive. Identical drives are recommended for performance as well as data storage efficiency.
RAID 0 Striping interleaves data across multiple drives
Physical Drives
The disk array's data capacity is equal to the number of disk drive members multiplied by the smallest drive's capacity. For example, one 100 GB and three 120 GB drives form a 400 GB (4 x 100 GB) disk array instead of 460 GB.
If physical drives of different capacities are used, there is unused capacity on the larger drives. RAID 0 logical drives on Vess consist of one or more physical drives.
| Advantages Disadvantages | |
| • Implements a striped disk array, the data is broken down into blocks and each block is written to a separate disk drive• I/O performance is greatly improved by spreading the I/O load across many channels and drives• No parity calculation overhead is involved | • Not a true RAID because it is not fault-tolerant• The failure of just one drive results in all data in an disk array being lost• Should not be used in mission critical environments |
Recommended Applications for RAID 0:
- Image Editing
• Pre-Press Applications
• Any application requiring high
RAID 1 - MIRROR
When a logical drive is mirrored, identical data is written to a pair of physical drives, while reads are performed in parallel. The reads are performed using elevator seek and load balancing techniques where the workload is distributed in the most efficient manner. Whichever drive is not busy and is positioned closer to the data is accessed first.
With RAID 1, if one physical drive fails or has errors, the other mirrored physical drive continues to function. Moreover, if a spare physical drive is present, the spare drive is used as the replacement drive and data begins to mirrored to it from the remaining good drive.
RAID 1 Mirrors identical data to two drives
Physical Drives
The logical drive's data capacity equals the smaller physical drive. For example, a 100 GB physical drive and a 120 GB physical drive have a combined capacity of 100 GB in a mirrored logical drive.
If physical drives of different capacities are used, there is unused capacity on the larger drive.
RAID 1 logical drives on Vess consist of two physical drives.
If you want a mirrored logical drive with more than two physical drives, see “RAID 1E – Enhanced Mirror” on page 557.
| Advantages Disadvantages | |
| Simplest RAID storage subsystem designCan increase read performance by processing data requests in parallel since the same data re-sides on two different drives | Very high disk overhead – uses only 50% of total capacity |
Recommended Applications for RAID 1:
- Accounting
- Payroll
- Financial
• Any application requiring very high availability
RAID 1E - ENHANCED MIRROR
RAID 1E offers the security of mirrored data provided by RAID 1 plus the added capacity of more than two physical drives. It also offers overall increased read/write performance plus the flexibility of using an odd number of physical drives. With RAID 1E, each data stripe is mirrored onto two physical drives. If one drive fails or has errors, the other drives continue to function, providing fault tolerance.
RAID 1E can mirror data over an odd number of drives
The advantage of RAID 1E is the ability to use an odd number of physical drives, unlike RAID 1 and RAID 10. You can also create a RAID 1E Logical Drive with an even number of physical drives. However, with an even number of drives, you obtain somewhat greater security with comparable performance using RAID 10.
RAID 1E logical drives consist of three or more physical drives. You can create an array with just two physical drives and specify RAID 1E. But the resulting ar-ray is actually a RAID 1.
| Advantages Disadvantages | |
| Implemented as a mirrored disk array whose segments are RAID 0 disk arraysHigh I/O rates are achieved thanks to multiple stripe seg-mentsCan use an odd number of disks | Very high disk overhead – uses only 50% of total capacity |
Recommended Applications for RAID 1E:
- Imaging applications
- Database servers
- General fileserver
RAID 5 - BLOCK AND PARITY STRIPE
RAID 5 organizes block data and parity data across the physical drives. Gener-ally, RAID Level 5 tends to exhibit lower random write performance due to the heavy workload of parity recalculation for each I/O. RAID 5 is generally considered to be the most versatile RAID level. It works well for file, database, application and web servers.
RAID 5 stripes all drives with data and parity information
The capacity of a RAID 5 logical drive equals the smallest physical drive times the number of physical drives, minus one. Hence, a RAID 5 logical drive with four 100 GB physical drives has a capacity of 300 GB. A RAID 5 logical drive with two 120 GB physical drives and one 100 GB physical drive has a capacity of 200 GB.
RAID 5 is generally considered to be the most versatile RAID level.
A RAID 5 on Vess consists of 3 to 32 physical drives.
Recommended Applications for RAID 5:
| Advantages Disadvantages | |
| ·High Read data transaction rate·Medium Write data transaction rate·Good aggregate transfer rate·Most versatile RAID level | ·Disk failure has a medium impact on throughput |
• File and Application servers
• WWW, E-mail, and News servers
- Intranet servers
RAID 6 - BLOCK AND DOUBLE PARITY STRIPE
RAID level 6 stores dual parity data is rotated across the physical drives along with the block data. A RAID 6 logical drive can continue to accept I/O requests when any two physical drives fail.
Hence, a RAID 6 logical drive with (7) 100 GB physical drives has a capacity of 500 GB. A RAID 6 logical drive
RAID 6 stripes all drives with data and dual parity
with (4) 100 GB physical drives has a capacity of 200 GB.
RAID 6 becomes more capacity efficient in terms of physical drives as the number of physical drives increases.
RAID 6 provides double fault tolerance. Your logical drive remains available when up to two physical drives fail.
RAID 6 is generally considered to be the safest RAID level.
A RAID 6 on Vess consists of 4 to 32 physical drives.
| Advantages Disadvantages | |
| High Read data transaction rateMedium Write data transaction rateGood aggregate transfer rateSafest RAID level, except for RAID 60 | High disk overhead – equivalent of two drives used for paritySlightly lower performance than RAID 5 |
Recommended Applications for RAID 6:
• Accounting and Financial
- Database servers
• Any application requiring very high availability
RAID 10 - MIRROR + STRIPE
Mirror + Stripe combines both of the RAID 1 and RAID 0 logical drive types. RAID 10 can increase performance by reading and writing data in parallel or striping, and duplicating the data, or mirroring.
PROMISE implements RAID 10 by creating a data stripe over one pair of disk drives, then mirroring the stripe over a second pair of disk drives. Some applications refer to this method as RAID 0+1.
PROMISE RAID 10 starts with a data stripe, then mirrors it
The data capacity RAID 10 logical drive equals the capacity of the smallest physical drive times the number of physical drives, divided by two.
In some cases, RAID 10 offers double fault tolerance, depending on which physical drives fail.
RAID 10 arrays require an even number of physical drives and a minimum of four.
For RAID 10 characteristics using an odd number of physical drives, choose RAID 1E.
| Advantages Disadvantages | |
| Implemented as a mirrored disk array whose segments are RAID 0 disk arraysHigh I/O rates are achieved thanks to multiple stripe segments | Very high disk overhead – uses only 50% of total capacity |
Recommended Applications for RAID 10:
- Imaging applications
- Database servers
- General fileserver
RAID 50 - STRIPING OF DISTRIBUTED PARITY
RAID 50 combines both RAID 5 and RAID 0 features. Data is striped across physical drives as in RAID 0, and it uses distributed parity as in RAID 5. RAID 50 provides data reliability, good overall performance, and supports larger volume sizes.
RAID 50 is a combination of RAID 5 and RAID 0
| Advantages Disadvantages | |
| ·High Read data transaction rate·Medium Write data transaction rate·Good aggregate transfer rate·High reliability·Supports large volume sizes | ·Higher disk overhead than RAID 5 |
Recommended Applications for RAID 50:
• File and Application servers
• Transaction processing
• Office application with many users accessing small files
The data capacity RAID 50 logical drive equals the capacity of the smallest physical drive times the number of physical drives, minus two.
RAID 50 also provides very high reliability because data is still available even if multiple physical drives fail (one in each axle). The greater the number of axles, the greater the number of physical drives that can fail without the RAID 50 logical drive going offline.
| Components Minimum Maximum | ||
| Number of Axles | 2 16 | |
| Physical Drives per Axle | 3 32 | |
| Physical Drives per Logical Drive | 6 256 | |
RAID 50 Axles
When you create a RAID 50, you must specify the number of axles. An axle re-fers to a single RAID 5 logical drive that is striped with other RAID 5 logical drives to make RAID 50. An axle can have from 3 to 32 physical drives, de-pending on the number of physical drives in the logical drive.
The chart below shows RAID 50 logical drives with 6 to 32 physical drives, the available number of axles, and the resulting distribution of physical drives on each axle.

RAID 60 - STRIPING OF DOUBLE PARITY
RAID 60 combines both RAID 6 and RAID 0 features. Data is striped across disks as in RAID 0, and it uses double distributed parity as in RAID 6. RAID 60 provides data reliability, good overall performance and supports larger volume sizes.
RAID 60 is a combination of RAID 6 and RAID 0
The total capacity of a RAID 60 logical drive is the smallest physical drive times the number of physical drives, minus four.
RAID 60 also provides very high reliability because data is still available even if multiple physical drives fail (two in each axle). The greater the number of axles, the greater the number of physical drives that can fail without the RAID 60 logical drive going offline.

RAID LEVEL MIGRATION
The term "Migration" means either or both of the following:
- Change the RAID level of a logical drive.
- Expand the storage capacity of a logical drive.
On Vess, RAID level migration is performed on the disk array but it applies to the logical drives. Migration does not disturb your data. You can access the data while the migration is in progress. When migration is done, your disk array has a different RAID level and/or a larger capacity.
MIGRATION REQUIREMENTS
The following conditions affect RAID level migration:
- The disk array and logical drive must show a green check icon.
- The Target disk array may require more physical drives than the Source disk array.
- If the Target disk array requires an EVEN number of physical drives but the Source disk array has an ODD number, ADD a physical drive as part of the migration process.
- You cannot reduce the number of physical drives in your disk array, even if the Target disk array requires fewer physical drives than the Source disk array.
- RAID 1 (mirroring) works with two drives only. Only a single-drive RAID 0 disk array can migrate to RAID 1. Other RAID Levels use too many drives to migrate.
- You cannot migrate a disk array when it is Critical or performing activities such as Synchronizing, Rebuilding, and PDM.
- For RAID 6 or RAID 60, you can only migrate between these two RAID le-vels. Destination RAID 60 axles can have up to 16 physical drives. Other limitations might apply.
SOURCE AND TARGET RAID LEVELS
The tables on the following pages show the migration options for each source logical drive by its RAID level. The available target RAID levels are shown with their requirements.
RAID 0
A RAID 0 source logical drive can migrate to the following target logical drives:
| Target | Requirements |
| RAID 0 | Add physical drives. |
| RAID 1 | 2 physical drives only.Only a single-drive RAID 0 can migrate to RAID 1 by adding 1 physical drive. |

| RAID 50 6 | physical drives minimum, 32 per axle maximum. |
| RAID 60 | 8 physical drives minimum, 32 per axle maximum.If existing physical drives have no unused space, add 1 or more physical drives. |
When you migrate RAID 10 logical drive, it becomes RAID 1E by default.
If you want a RAID 10 logical drive, there must be an even number of physical drives and you must specify RAID 10 for the target logical drive.
RAID 50
A RAID 50 source logical drive can migrate to the following target logical drives:
| Target | Requirements |
| RAID 0 | None. |

| RAID 10 | Even number of physical drives. |
| RAID 50 | Add physical drives. 32 per axle maximum. |
| RAID 60 | 8 physical drives minimum, 32 per axle maximum.If existing physical drives have no unused space, add 1 or more physical drives. |
You can add physical drives to a RAID 50 array but you cannot change the number of axles.
RAID 60
A RAID 60 source logical drive can migrate to the following target logical drives:
| Target | Requirements |
| RAID 6 | 32 physical drives maximum.RAID 60 must have less than 32 physical drives.If existing physical drives have no unused space, add 1 or more physical drives. |
| RAID 60 | Add physical drives. 32 per axle maximum. |
You can add physical drives to a RAID 60 array but you cannot change the number of axles.
STRIPE SIZE
Stripe Size, also called “Stripe Block Size,” refers to the size of the data blocks written to, and read from, the physical drives. Stripe Size is specified when you create a logical drive. You can choose Stripe Size directly when you use the Wizard Advanced Configuration function to create a logical drive.
You cannot change the Stripe Size of an existing logical drive. You must delete the logical drive and create a new one.
The available Stripe Sizes are 64 KB, 128 KB, 256 KB, 512 KB, and 1 MB. 64 KB is the default. There are two issues to consider when choosing the Stripe Size:
- You should choose a Stripe Size equal to, or smaller than, the smallest cache buffer found on any physical drive in the disk array. Selecting a larger value slows read/write performance because physical drives with smaller cache buffers need more time for multiple accesses to fill their buffers.
- If your data retrieval consists of fixed data blocks, such as with some data-base or video applications, then you should choose that size as your Stripe Size.
- If you do not know the cache buffer or fixed data block sizes, choose 64 KB as your Stripe Size. Generally speaking,
- Email, POS, and web servers prefer smaller stripe sizes.
• Video and database applications prefer larger stripe sizes.
SECTOR SIZE
A sector is the smallest addressable area on a physical drive. Sector size refers to the number of data bytes a sector can hold. A smaller sector size is a more efficient use of a physical drive's capacity. 512 bytes (512 B) is the most common sector size, and the default in WebPAM PROe.
PREFERRED CONTROLLER ID
When you create a logical drive using the Advanced method of disk array creation, you can specify the Preferred Controller ID:
- Controller 1 – Assign all logical drives to Controller 1
- Controller 2 – Assign all logical drives to Controller 2.
• Automatic – Alternate logical drive assignments between Controllers 1 and 2.
Automatic is the default and preferred setting because it balances the logical drive assignments for you.
See “Creating a Disk Array Manually” on page 190, “Creating a Disk Array with the Wizard” on page 191, and “Advanced Configuration” on page 87.
INITIALIZATION
Initialization is done to logical drives after they are created from a disk array. Full initialization sets all data bits in the logical drive to a specified pattern, such as all zeros. The action is useful because there may be residual data on the logical drives left behind from earlier configurations. For this reason, Initialization is recommended for all new logical drives. See “Initializing a Logical Drive” on page 207.
Caution
When you initialize a logical drive, all the data on the logical drive is lost. Backup any important data before you initialize a logical drive.
PARTITION AND FORMAT
Like any other type of fixed disk media in your system, a RAID logical drive must also be partitioned and formatted before use. Use the same method of partitioning and formatting on an logical drive as you would any other fixed disk.
Depending on the operating system you use, there may or may not be various capacity limitations applicable for the different types of partitions.
SPARE DRIVES
Spare drive technology includes:
- "Definition" (below)
- "Options" (below)
- "Requirements" on page 582
- "Transition" on page 582
DEFINITION
A spare drive is a physical drive that you designate to automatically replace the failed physical drive in a disk array. See “Creating a Spare Drive Manually” on page 215.
The general recommendation is to:
- Provide at least one spare drive for every 16 physical drives in the RAID system
- Configure the spares as global revertible spare drives
OPTIONS
There are several options you can specify for a spare drive:
- System Options
- Revertible – Returns to its spare drive assignment after you replace the failed physical drive in the disk array and run the Transition function.
• Media Patrol – By default, Media Patrol runs on spare drives unless you disable it. - Spare Type
- Global – Can be used by any disk array
• Dedicated – Can be used only by the assigned disk array
• Media Type (type of physical drive) - Hard Disk Drive (HDD)
• Solid State Drive (SSD)
REQUIREMENTS
The spare drive must:
- Have adequate capacity to replace the largest physical drive in your disk arrays.
- Be the same media type as the physical drives in your disk arrays.
• A revertible spare drive requires: - You to replace the failed physical drive in the disk array
• You to run the Transition function
TRANSITION
Transition is the process of replacing a revertible spare drive that is currently part of a disk array with an unconfigured physical drive or a non-revertible spare. The revertible spare drive returns to its original status. In order to run the Transition function, the spare drive must be revertible.
In addition, you must specify an unconfigured physical drive of the same or larger capacity and same media type as the revertible spare drive.
RUNNING A TRANSITION
The Transition feature enables you to specify “permanent” spare drives for your Vess subsystem. Transition is the process of replacing a revertible spare drive that is currently part of a disk array with an unconfigured physical drive or a non-revertible spare. The revertible spare drive returns to its original status.
Transition happens automatically when the following sequence of events takes place:
- You create a revertible spare drive. See “Creating a Spare Drive Manually” on page 215.
• A physical drive assigned to your disk array fails and the array goes critical or degraded. - Vess automatically rebuilds your array to the revertible spare drive and the array becomes functional again.
• You replace the failed physical drive with a new physical drive of equal or greater capacity. - Vess automatically transitions (moves) the data from the revertible spare to the new physical drive.
The new physical drive becomes part of the array and the revertible spare drive returns to its original spare status.
Transition happens manually when you specify a different unconfigured physical drive to transition (move) the data from the revertible spare drive.
See the example on the following pages.
Example
Following is an example to explain the Transition function.
In the example above, there is a four-drive RAID 5 disk array and a global spare drive. Physical drives 1, 2, 3, and 4 belong to the disk array. Physical drive 5 remains unconfigured. Physical drive 6 is a revertible spare drive.

| Category | Segment 1 | Segment 2 | Segment 3 | Segment 4 | Segment 5 | Segment 6 | |---|---|---|---|---|---|---| | 1 | Green Dot | Blue Dot | Green Dot | Red Dot | Grey Dot | Green Dot | | 2 | Green Dot | Blue Dot | Green Dot | Red Dot | Grey Dot | Green Dot | | 3 | Grey Dot | Blue Dot | Red Dot | Grey Dot | Grey Dot | Green Dot | | 4 | Grey Dot | Blue Dot | Green Dot | Grey Dot | Grey Dot | Green Dot | | 5 | Grey Dot | Blue Dot | Grey Dot | Grey Dot | Grey Dot | Green Dot | | 6 | Grey Dot | Blue Dot | Green Dot | Grey Dot | Grey Dot | Green Dot | The chart is labeled as 'Failed Drive' and 'Rebuild to Spare'. The bars are visually grouped by color: green for failed drive, gray for rebuild to spare, blue for rebuild to spare.If a physical drive fails in a disk array and there is a spare drive of adequate capacity available, the controller automatically rebuilds the array using the spare drive. In this example, physical drive 3 failed and the array is rebuilt using physical drive 6, the revertible spare drive.
When the rebuild is complete, the spare drive has replaced the failed drive. In this example, failed drive 3 was replaced by spare drive 6. The disk array now consists of physical drives 1, 2, 4, and 6.
There is no spare drive at this moment. Even if physical drive 5 is of adequate capacity, it has not been designated as a spare, therefore the controller cannot use it as a spare.
Automatic Transition
At this juncture, you would replace the failed drive in slot 3 with a new one of the same or greater capacity.

K["6"] --> L["Spare Drive"]
When the Vess controller detects the new drive in slot 3, the controller:
• Automatically transitions the data on drive 6 to drive 3
• Returns drive 6 to spare status
When the Automatic Transition is finished, physical drives 1, 2, 3, and 4 belong to the disk array and physical drive 6 is a revertible spare drive. The original configuration is restored.
Manual Transition
If you wanted to use the drive in slot 5 as a member of the disk array, rather than the drive in slot 3, you would run the Transition function manually. See “Running a Transition on a Spare Drive” on page 218.

When the Manual Transition is finished, physical drives 1, 2, 4, and 5 belong to the disk array and physical drive 6 is a revertible spare drive.
At this point, you would replace the drive in slot 3. The new drive in slot 3 re-mains unconfigured until you assign it to a disk array or as a spare.
RAID CONTROLLERS
RAID controller technology includes;
- "LUN Affinity" (below)
- "ALUA" (below)
• "Cache Policy" on page 589 - "Read Cache Policy" on page 589
• "Write Cache Policy" on page 590
• "Power Saving" on page 592
• "Capacity Coercion" on page 592
LUN AFFINITY
Vess subsystems with dual RAID controllers include a LUN Affinity feature. Normally, either controller can access all logical drives. LUN Affinity enables you to specify which controller can access each logical drive. Use this feature to balance the load of your logical drives between the two controllers.
To use LUN Affinity you must:
• Have two RAID controllers in the subsystem.
- Set the redundancy type to Active-Active. See “Making Subsystem Settings” on page 102.
- Enable LUN Affinity. See "Making Controller Settings" on page 114.
On subsystems with two RAID controllers, when Cache Mirroring is disabled, LUN Affinity is enabled automatically.
ALUA
Vess supports Asymmetric Logical Unit Access (ALUA) on Linux OSes. ALUA is a multipathing tool. It enables an initiator (your host PC or server) to discover target port groups that provide a common failover / failback behavior for your LUNs. ALUA enables the host to see which paths are in an optimal state and which are not.
To use ALUA you must:
• Have two RAID controllers in the subsystem.
- Set the redundancy type to Active-Active. See "Making Subsystem Settings" on page 102.
- Enable LUN Affinity and ALUA. See “Making Controller Settings” on page 114.
CACHE POLICY
As it is used with Vess, the term cache refers to any of several kinds of high-speed, volatile memory that hold data moving from your computer to the physical drives or vice-versa. Cache is important because it can read and write data much faster than a physical drive. There are read caches, which hold data as it is read from a physical drive; and write caches, which hold data as it is written to a physical drive.
In order to tune the cache for best performance in different applications, user-adjustable settings are provided. Cache settings are made on the RAID controller. See “Making Controller Settings” on page 114.
READ CACHE POLICY
- Read Cache – The read cache is enabled but no pre-fetch action.
- Read Ahead – The read cache and predictive pre-fetch feature are enabled. Read-ahead anticipates the next read and performs it before the request is made. Can increase read performance.
- Forced Read Ahead – The read cache and aggressive pre-fetch feature are enabled. See “Forced Read-Ahead Cache” below.
- No Cache – The read cache is disabled.
WRITE CACHE POLICY
- Write Back – Data is written first to the cache, then to the logical drive. Better performance. Vess has a cache backup battery to protect data in the cache from a sudden power failure.
- Adaptive Writeback – See “Adaptive Writeback Cache” below.
- Write Thru – Also “Write Through.” Data is written to the cache and the logical drive at the same time. Safer.
If your write cache policy is set to Write Back, the write policy automatically changes to Write Thru when all of the following conditions occur:
• The logical drive write policy is set to Write Back
- The Adaptive Writeback Cache feature is enabled
• The cache backup battery goes offline
When the battery comes back online, the write policy automatically changes back to Write Back.
Also see "Viewing Battery Information" on page 120.
Forced Read-Ahead Cache
On the Vess subsystem, you can set the logical drive read cache policy to Forced Read Ahead an enable the aggressive pre-fetch feature.
The Forced Read-Ahead cache policy setting provides predictive pre-fetching of data requests, allowing the controller to aggressively buffer large chunks of data in cache memory to prevent frame drops on high-bandwidth video playback. Not normally enabled for non-video applications.
ADAPTIVE WRITEBACK CACHE
On the Vess subsystem, you can set the logical drive write cache policy to Write Thru or Write Back.
If you set the write cache policy to Write Back, your data is first written to the controller cache, and later to the logical drive. This action is conducted to improve performance. In order to preserve the data in the cache in the event of a power failure, the subsystem has a backup battery that provides continuous power to maintain the cache. To see an estimate of how long the battery can power the cache, see “Viewing Battery Information” on page 120.
The Adaptive Writeback Cache feature protects your data by changing the write cache settings while the cache backup battery is offline. When all of the following conditions occur:
• The logical drive write policy is set to Write Back.
• The Adaptive Writeback Cache feature is enabled.
- The cache backup battery goes offline. (See definition in Note below)
The write policy automatically changes to Write Thru. When the battery comes back online, the write policy automatically changes back to Write Back.
To enable the Adaptive Writeback Cache option, see "Making Controller Settings" on page 114.

The condition "cache battery goes offline" can be due to one of the following circumstances:
- Battery not installed.
- Battery remaining capacity is not enough to keep data, outcome depends if

Host Cache Flushing
On the Vess subsystem, you can enable or disable host cache flushing.
When enabled, host cache flushing guards against data loss in the event of a power failure. However RAID performance is slightly reduced.
When disabled, the Vess subsystem has greater sustained bandwidth and lower latency, which are helpful for real-time video capture.
When you operate the Vess with host cache flushing disabled, use a UPS to protect against data loss.
Preferred Controller ID
See "Preferred Controller ID" on page 579.
POWER SAVING
Power saving is a method of conserving energy by applying specific actions to hard disk drives (HDD). After an HDD has been idle for the set period of time, you can elect to:
- Park the read/write heads – Referred to as Power Saving Idle Time on Vess.
- Reduce disk rotation speed – Referred to as Power Saving Standby Time on Vess.
- Spin down the disk (stop rotation) – Referred to as Power Saving Stopped Time on Vess.
Power management must be:
- Set on the RAID controller. See "Making Controller Settings" on page 114.
- Enabled on each HDD. See "Making Disk Array Settings" on page 193.
CAPACITY COERCION
This feature is designed for fault-tolerant logical drives (RAID 1, 1E, 5, 10, 50, and 60). It is generally recommended to use physical drives of the same size in your disk arrays. When this is not possible, the system adjusts for the size differences by reducing or coercing the capacity of the larger drives to match the smaller ones. With Vess, you can choose to enable capacity coercion and any one of four methods.
Enable capacity coercion and choose a method, see See "Making Controller Settings" on page 114.
- GB Truncate – (Default) Reduces the useful capacity to the nearest 1,000,000,000 byte boundary.
- 10GB Truncate – Reduces the useful capacity to the nearest 10,000,000,000 byte boundary.
- Group Rounding – Uses an algorithm to determine how much to truncate. Results in the maximum amount of usable drive capacity.
- Table Rounding – Applies a predefined table to determine how much to truncate.
Capacity coercion also affects a replacement drive used in a disk array. Normally, when an physical drive fails, the replacement drive must be the same capacity or larger. However, the capacity coercion feature permits the installation of a replacement drive that is slightly smaller (within 1 gigabyte) than the remaining working drive. For example, the remaining working drives can be 80.5 GB and the replacement drive can be 80.3, since all are rounded down to 80 GB. This permits the smaller drive to be used.
Without capacity coercion, the controller does not permit the use of a replacement physical drive that is slightly smaller than the remaining working drives.

INITIATOR
An initiator functions as the client, in this case, your host PC or server. The in-itiator makes requests to and receives responses from an iSCSI target on the Vess RAID subsystem.
Each initiator has a unique iSCSI qualified name (IQN). You specify the initiator by that name when you map a LUN or logical drive to
Software
A software initiator uses code to implement iSCSI. The software emulates SCSI devices for a computer by speaking the iSCSI protocol. Software initiators are available for most mainstream operating systems, and this type is the most common mode of deploying iSCSI on computers.
For more information, see your iSCSI driver user documentation.
Hardware
A hardware initiator uses dedicated hardware in combination with software running on it, to implement iSCSI. A common example is an iSCSI host bus adapter (HBA) card.
The iSCSI HBA is a 1-gigabit or 10 gigabit Ethernet network Interface card (NIC) that plugs into a PCI-Express slot. It looks like a SCSI device to the host PC or server's operating system.
The iSCSI HBA uses a TCP/IP Offload Engine (TOE) to perform iSCSI and TCP processing and managing interrupts, leaving the host PC or server's microprocessor free to run other applications.
For more information, see your iSCSI HBA user documentation.
TARGET
The target represents a storage device, in this case the Vess RAID subsystem. Each target has a unique iSCSI qualified name (IQN).
Target options include Digests and CHAPs.
DIGESTS
A header digest adds a 32-bit CRC digest to detect data corruption in the header portion of each iSCSI packet.
A data digest adds a 32-bit CRC digest to detect data corruption in the data portion of each iSCSI packet.
If a data packet arrives with an invalid CRC digest, the data packet is rejected.
Header and data digests work best with initiators equipped with a TOE. Refer to your iSCSI HBA. For more information, see your iSCSI HBA user documentation.
CHAPs
Challenge Handshake Authentication Protocol (CHAP) is an authentication
mechanism used to authenticate iSCSI sessions between initiators and targets.
A unidirectional or peer CHAP authenticates from the target (Vess) to the initiator (host PC or server).
A bi-directional or local CHAP authenticates target to initiator and initiator to target.
PORTAL
A portal is the logical point of connection between the Vess and the iSCSI network. Portals use an IP address and a TCP port number to identify an IP storage resource. Vess supports up to 32 iSCSI portals per iSCSI port. Vess uses TCP port 3260.
Vess supports both IPv4 and IPv6 addresses.
Portals on Vess support three types of port associations:
• PHY – A simple connection through one port.
- VLAN – Virtual Local Area Network. The portal is part of a virtual network. Used when a dedicated network is not available for iSCSI.
- Trunk – An aggregation of two or more iSCSI ports on the same RAID controller. Also known as a link aggregation. This feature combines ports to increase bandwidth.
Once you have made a port association, you cannot change it. If you have no portals with the port association you want, create a new portal.
Each iSCSI portal can belong to a different VLAN. Vess supports 32 VLANs.
PORT
A port is the physical point of connection between the Vess and the iSCSI network. There are four ports on each RAID controller for a total of eight. When you create a portal, you specify one or more ports. Each port has a unique MAC address.
There are two options for each iSCSI port:
- Enable Port – Turns the port on or off.
- Jumbo Frame – Enables jumbo frame support on the port.
The standard Ethernet frame is 1518 bytes, with 1500 bytes for payload. A jumbo frame ranges from 1500 bytes to 9000 bytes of payload. Because jumbo frames carry more data, they are used to reduce network management overhead, thereby increasing network throughput.
TRUNK
A trunk is an aggregation of two or more iSCSI ports on the same RAID controller. Also known as a link aggregation. This feature combines ports to increase bandwidth.
Trunks are identified by their Trunk IDs.
When you create a trunk, you specify:
- Controller ID – RAID controller whose iSCSI ports you are using.
• Master port – Any available iSCSI port. - Slave ports – The remaining available iSCSI ports.
SESSION
A session is a group of TCP connections that link an iSCSI initiator with a target. Each RAID controller supports a maximum of 128 sessions.
- When the server replies, the client knows that the link is up (the connection between client and server works).
- If there is no reply, the client assumes the link is down and routes future data over another path until the original link is up again.
iSNS
Internet Storage Name Service (iSNS) is a protocol that facilitates automated discovery, management, and configuration of iSCSI devices on a TCP/IP net-work. iSNS service runs on an iSNS server on your network.
You can enable iSNS on the Vess and specify the IP address and port number of the iSNS server.
CHAP
Challenge Handshake Authentication Protocol (CHAP) is an authentication
mechanism used to authenticate iSCSI sessions between initiators and targets.
A uni-directional or peer CHAP authenticates from the target (Vess) to the initiator (host PC or server).
A bi-directional or local CHAP authenticates target to initiator and initiator to target.
PING
Ping is a computer network administration utility that tests whether a device is accessible over the IP network.
Ping sends echo request packets to the target node, such as your host PC or server, and waits for a response. It measures the time from transmission to reCEPTION and records any packet loss.
Vess can ping through its virtual management port and each of its iSCSI data ports. You must input the IP address of the target client.
INTERNET PROTOCOLS
Vess supports the IPv4 and IPv6 protocols.
| Protocol Addresses Example | |||
| IPv4 | 32-bits | 4.3 x 109 | 192.168.10.85 |

Vess R2000 is BEEPING
Vess's alarm has five different patterns, as shown below.
Audible alarm sound patterns
bar
| Category | Segment 1 (%) | Segment 2 (%) | Segment 3 (%) | |---|---|---|---| | 1 | 1 | 0 | 0 | | 2 | 0 | 0 | 0 | | 3 | 0 | 0 | 0 | | 4 | 0 | 0 | 0 | | 5 | 0 | 0 | 0 |When you first power-up the Vess, it beeps twice to show normal operation.
See pattern 1, in the figure above.
The audible alarm sounds at other times to inform you that the Vess needs attention. But the alarm does not specify the condition.
When the alarm sounds:
- Check the front and back of Vess enclosure for red or amber LEDs.
- If email notification is enabled, check for new messages.
- Check for yellow! red X icons.
- Check the event log.
• See "Viewing Runtime Events" on page 172 and "Viewing NVRAM Events" on page 173.
When a continuous tone sounds, there are multiple alarm patterns sounding at the same time.
This action disables the buzzer for all events.
To silence the buzzer:
- Click the Device tab.
- Click the Component List icon.
- Click the Buzzer and click the Settings button.
- Uncheck the Enable Buzzer box.
- Click the Save button.
LEDs DISPLAY AMBER OR RED
Vess R2000 LEDs are described in these sections:
- "LEDs on the Front of the Vess R2000" on page 606
- "Drive Carrier LEDs" on page 608
- "LEDs on the Back of the Vess R2000" on page 609
LEDs on the Front of the Vess R2000
When the power is on, the LEDs on the front of the Vess R2000 light up.
Front right LED display of Vess R2600
When boot-up is finished and the Vess is functioning normally:
• Power, Global Enclosure Status, and Global RAID Status LEDs display green continuously.
• Controller Activity LED flashes green when there is controller activity.
• System Heartbeat LED blinks blue (once a second), and repeats the pattern.
Steady means the LED is on.
Blinking means a regular on/off pattern.
Flashing means an intermittent and irregular on/off pattern.
Dark means the LED is off.
See the table below.

Steady means the LED is on.
Blinking means a regular on/off pattern.
Flashing means an intermittent and irregular on/off pattern.
Dark means the LED is off.
"Enclosure Problems" on page 623, "RAID Controller Problems" on page 627, and "Physical Drive Problems" on page 632.
The Locator feature triggered from WebPAM PROe causes the LEDs to blink on and off for one minute. That action helps you find the physical component.
DRIVE CARRIER LEDs
The Vess spins up the disk drives sequentially to equalize power draw during start-up. After a few moments:
- The Power/Activity LED displays blue when a physical drive is present.
- The Drive Status LED displays green when the physical drive is configured as a member of a disk array or as a spare. When the physical drive is unconfigured, the LED is dark.

The Locator feature triggered from WebPAM PROe causes the LEDs to blink on and off for one minute. That action helps you find the physical component.
LEDs ON THE BACK OF THE VESS R2000
When the FRU Status LED on Vess's front panel shows amber or red, check the LEDs on the back of Vess R2000 These LEDs give the status of the field replaceable units:
- RAID controller
• Power supply (includes cooling fan)
Under normal conditions, the controller status LED and battery status LED display green. The dirty cache LED is dark.
CONTROLLER LED BEHAVIOR
When boot-up is finished and the Vess R2600 subsystem is functioning normally, the Controller status LED displays green continuously; the Management port LEDs display green or flash depending on your network connection; the FC, iSCSI, and SAS Expansion LEDs display green or flash during port activity.
| LED Description | |
| SAS Expansion | Lights green when connected, flashes green when active. |
| Controller Status | This displays the current operational status of the controller. A steady (unblinking) green light indicates the controller is operational. |
| Dirty Cache | Blinks amber if cache is dirty, meaning that the controller memory cache contains data, otherwise this is dark. |
| USB | A steady green light indicates a valid USB connection, this is dark when not connected (no device attached). |
See tables on next page for data port LED behavior.
iSCSI port LED behavior
| 1G iSCSILink/Act and Speed | Two LEDs are located above each port. The left LED lights GREEN when connected, flashes GREEN when there is activity on the port and remains dark no connection has been established. The LED on the right of each port indicates connection speed, GREEN is 100 Mbps, AMBER is 1000 Mbps. |
| 10G iSCSI(Vess R2600ti)Link/Act and Speed | Two LEDs are located above each port. The left LED lights GREEN when connected, flashes GREEN when there is activity on the port and remains dark no connection has been established. The LED on the right of each port indicates connection speed, AMBER is 1000 Mbps, GREEN is 10000 Mbps.Note that the 10G port speed LED indicator is different than the 1G ports, a GREEN speed LED is the fastest speed on the 10G port, in contrast to the 1G iSCSI I/O ports where GREEN is the slowest speed. AMBER indicates 1000 Mbps on both port types. |

CHECKING COMPONENT INSTALLATION
To check a component's installation, remove the component, then reinstall the component in its original location. In most cases, this action fixes a bad connection and allows Vess to detect the component. If this action does not correct the problem, replace the unit.
On Vess R2000 systems with dual controllers, when one controller's Status LED is amber and the other controller's Status LED is flashing red, it means that the controller with the flashing red LED has entered maintenance mode. See "RAID Controller Problems" on page 627.
If the Controller Status LED continues to display amber after startup, contact PROMISE Technical Support. See "Contacting Technical Support" on page 666.
The Dirty Cache LED flashes during input/output operation. If the LED shines amber and the power is off, there is unsaved data in the cache. Do NOT power down the Vess while this LED is on.
CLU REPORTS A PROBLEM
The CLU reports information passively, that is you must determine which functions to check based on the sound of the Vess R2600's audible alarm and any amber or red LEDs. See "Vess R2000 is Beeping" on page 604 and "LEDs Display Amber or Red" on page 605 for more information.
Check the event logs first. Then check the reported component.

USB SUPPORT REPORTS A PROBLEM
This procedure requires a USB flash device:
- Formatted to FAT 32
• At least 50 MB of free space
Caution
Verify that there is no firmware image file on the USB flash device. If a firmware image file is present, the RAID controller might attempt a firmware update.
To collect a service report using the USB Support feature:
- Insert the USB flash device into one of the USB ports on the front left of the Vess R2000.
The controller status LED blinks green in half-second intervals. - Wait until the controller activity LED stops blinking green and displays steady green.
- Remove the USB flash device.
- Insert the USB flash device into a USB port on your PC.
- On the USB flash device, open the OPAX_xxxxxx folder to obtain the re-port and log.
ENCLOSURE PROBLEMS
Enclosure Problems include:
• "Diagnosing an Enclosure Problem" (below)
• "Overheating" on page 625
• "Power Supplies" on page 626
• "Batteries" on page 626
DIAGNOSING AN ENCLOSURE PROBLEM
Check System Status on the Dashboard tab. If a yellow ! or red X appears in the System Status box:
- Click the name link of the component with the red X icon.
The Components List of the Device tab displays.
- Mouse-over Enclosure with the red X icon and click the View button.
The components list expands and shows the power supplies (PSU) and Cooling Units of the Vess R2000 enclosure.
- Click the Back View icon on the Device tab.
- Click the picture of the enclosure.
A popup messages displays the status of each component.
When a power supply fan fails, you must replace the power supply. See "Replacing a Power Supply" on page 540.
If the system reports a fan malfunction, contact Technical Support. See "Contacting Technical Support" on page 666 immediately to schedule replacement of the suspect power supply as soon as possible. Running the unit in this condition for more than three weeks may shorten subsystem life and void your warranty.

Overheating is a potentially serious condition because the excessively high temperatures can lead to physical drive failure and controller malfunction.
Overheating usually results from:
- Fan failure
- Inadequate air circulation around the enclosure
Important
In the event of a Cooling Unit failure, DO NOT remove the failed unit until there is a replacement available and on hand. A single functioning Cooling Unit is adequate for cooling the system as long as the failed Cooling Unit remains in place. Removing the failed unit without replacing it will adversely affect airflow within the enclosure resulting in critical overheating and shutdown of the enclosure.
See "Replacing a Power Supply" on page 540.
Inadequate Air Circulation
Air circulation around the Vess R2600 enclosure might be a more complex problem. Use the thermometer icons to help you locate the specific hot spot. Check for these conditions:
• Accumulated dust or objects blocking the fans
- Ambient temperature above 35ircC (95°F) where the subsystem is operating
- Failed Cooling Unit
- Less than a minimum of 13 cm (5 inches) space between the back of the enclosure and the wall or other object
To cool down an enclosure:
- Correct any problems identified above.
• Power it down and let it sit for an hour or longer.
If a Cooling Unit must be replaced, do not remove the failed unit until a replacement unit is available. A hole on the back of the enclosure created by a missing Cooling Unit affects air circulation which will cause controller units to overheat and shut down. If a replacement Cooling Unit is not available, leave the failed unit in place until
one is available. See "Replacing a Cooling Unit"
See "Shutting Down the Subsystem" on page 111.
POWER SUPPLIES
Vess R2600 subsystems are equipped with redundant power supplies. The advantage of N+1 power supplies is that should one fail, the other continues to power the subsystem until the faulty one can be replaced. The subsystem is capable of operation on N power supplies.
The power supplies are hot-swappable, meaning you can leave the subsystem running when you replace the bad one. Be careful, however, to remove the faulty power supply and not the good one, or the subsystem comes to an immediate stop and your data is unavailable until the subsystem is powered and booted again.
See "Replacing a Power Supply" on page 540.
POWER FAN FAILURE
In the Vess R2600 subsystems, the power supply fans are used for cooling the power supply. When a power supply fan fails, you must replace the power supply. See "Replacing a Power Supply" on page 540.
BATTERIES
The Cooling Units in the Vess R2600 subsystem use a battery for backup power to protect data in the cache. Should a power failure occur, the battery enables the cache to hold data up to 72 hours. The battery recharges during normal subsystem operation.
In most cases, installing a replacement battery corrects a marginal or failed condition. The battery is located inside the Cooling Unit housing. To replace a battery, first replace the Cooling Unit with the battery that needs to be replaced. See "Replacing a Cache Backup Battery" and "Reconditioning a Battery" on page 121.
RAID CONTROLLER PROBLEMS
RAID controller problems include:
- "Maintenance Mode" (below)
- "Storage Tab" on page 620
- “Taking a RAID Controller out of Maintenance Mode” on page 629
- "Unsaved Data in the Controller Cache" on page 631
Controller problems occur when one of the controllers goes into maintenance mode.
MAINTENANCE MODE
For Vess with two RAID controllers, one of them enters maintenance mode in the event of:
- A difference of some kind between the two controllers (described below)
• An internal controller failure
When a controller enters maintenance mode, it goes offline and it displays N/A (not accessible) under Readiness Status.
You must find and correct the cause of the problem and then take the controller out of maintenance mode (see page 629).
FINDING AND CORRECTING THE CAUSE OF THE PROBLEM
External Checks
Make the following external checks to your Vess subsystem. Be sure that:
- Both RAID controllers are present, fully inserted into their slots, and locked into place.
- The RAID controllers match, meaning both are the same model
- All SAS expansion cables from the RAID controllers to external JBOD units in good condition and are securely connected.
Important
A disconnected SAS expansion cable causes the two RAID controllers to see a different set of configured drives. This condition is the most common cause of a controller entering maintenance mode.
Internal Checks
If all external checks are OK, take the following actions:
- Shut down the Vess.
See "Shutting Down the Subsystem" on page 111. - Remove one of the RAID controllers.
See "Replacing a RAID Controller – Dual Controllers" on page 545. - Restart the Vess.
-
After the Vess is fully booted, view the controller information.
"Viewing Controller Information" on page 113. -
Observe and record the following information about the first controller:
-
SDRAM memory size
- Hardware version
-
Firmware version
-
Shut down the Vess.
- Remove the first controller and install the second controller.
- Repeat steps 3 through 6. Then compare your records.
- Correct any differences between the two controllers. See "Updating Firmware on a RAID Subsystem" on page 118.
TAKING A RAID CONTROLLER OUT OF MAINTENANCE MODE
If you shut down the Vess subsystem in the process of correcting the maintenance mode problem, the affected RAID controller boots into normal mode when the Vess restarts. No further action is required.
If you corrected the problem without shutting down the Vess subsystem, choose one of the following methods to take the controller out of maintenance mode:
- Restart the Vess subsystem. See "Restarting the Subsystem" on page 110.
- Establish a serial connection, then use the CLI (see below) or
- Establish a Telnet connection, then use the CLI (see page 630)
Serial Connection
To clear maintenance mode using a serial connection:
-
Change your terminal emulation program settings to match the following specifications:
-
Bits per second: 115200
- Data bits: 8
- Parity: None
- Stop bits: 1
-
Flow control: none
-
Start your PC's terminal VT100 or ANSI emulation program.
- Press Enter once to launch the CLI.
The login screen appears.
The following steps show the default Administrator user name and pass-word. Use your own user name and password if you have changed these.
- At the Login prompt, type administrator and press Enter.
- At the Password prompt, type password and press Enter.
The CLI screen appears.
The prompt should display MAINTENANCE MODE@cli>.
If the prompt dis-plays your login name, such as administrator@cli>, log into the other controller.
- At the MAINTENANCE MODE@cli> prompt, type maintenance -a exit and press Enter.
The controller reboots. The login screen again appears.
- Close the Serial connection.
Telnet Connection
This procedure requires you to know the IP address of the controller.
To clear maintenance mode using a Telnet connection:
- Go to the command line prompt (Windows) or click the terminal icon (Linux), then run:
telnet 192.168.1.56 2300
The IP address above is only an example. 2300 is the default Telnet port for Vess.
The login screen appears.
The following steps show the default Administrator user name and pass-word. Use your own user name and password if you have changed these.
- At the Login prompt, type administrator and press Enter.
- At the Password prompt, type password and press Enter.
The CLI screen appears.
The prompt should display MAINTENANCE MODE@cli>. If the prompt dis-plays your login name, such as administrator@cli>, log into the other controller.
- At the MAINTENANCE MODE@cli> prompt, type maintenance -a exit and press Enter.
The controller reboots. The Telnet session ends.
UNSAVED DATA IN THE CONTROLLER CACHE
The dirty cache LED (marked with the icon) informs you that there is data in the cache that has not been saved to non-volatile memory. Such data is sometimes called "dirty," not to suggest it is corrupted in some way but because it has not been saved to a physical drive.
Dirty Cache LED
Caution
If there is unsaved data in the controller's cache, the dirty cache LED shines amber. During this time, do NOT power down the Vess. Wait until the LED goes dark.
PHYSICAL DRIVE PROBLEMS
Physical drives are the foundation of data storage. A physical drive problem can affect your entire RAID system.
When a yellow ! icon or a red X icon appears beside a physical drive, check the drive's operational status:
- Click the Device tab.
- Click the Physical Drive icon.
- Click the physical drive you want, then click the View button.
Look under Operational Status for the condition of the physical drive.
- Offline – Check the drive for:
- PFA Condition – Caused by a bad block or sector. See Note 1 below.
- Stale Condition – Caused by obsolete array information on the physical drive. See Note 2 below.
- Not Usable – This condition occurs when you have:
- Two controllers in your RAID subsystem and a SATA drive without a SAS-to-SATA adapter. See Note 3 below.
- A missing or defective SAS cable between the RAID subsystem and a JBOD expansion unit.
- Drive Failed or Dead – The physical drive cannot be repaired. You must replace the failed drive. See Note 4 below.
Note 1: Clear the error condition. Then the physical drive is available. See "Clearing a Stale or a PFA Condition" on page 187.
Note 2: Identify the disk array to which the physical drive belongs. Then delete the disk array. If the error condition remains on the physical drive, clear the error condition.
Note 3: Obtain SAS-to-SATA adapters though PROMISE Technology, at
http://www.promise.com. See "Installing Physical Drives" on page 35 for installation instructions.
Note 4: You can set the number of bad blocks tolerated before the controller marks a physical drive as Dead. See "Managing Background Activities" on page 144, "Making PDM Settings" on page 155. See also "Running Media Patrol on a Disk Array" on page 194 and "Disk Array Degraded / Logical Drive Critical" on page 633.
DISK ARRAY AND LOGICAL DRIVE PROBLEMS
Disk array and logical drive problems include:
- "Disk Array Degraded / Logical Drive Critical" (below)
- "Disk Array Offline / Logical Drive Offline" on page 634
- "Repairing an Offline Disk Array or Logical Drive" on page 635
- "Rebuilding a Disk Array" on page 636
- "Incomplete Array" on page 636
Disk array problems typically result from a physical drive failure. The most common problem is a degraded disk array. The RAID controller can rebuild a degraded disk array. See "Rebuilding a Disk Array" on page 636.
DISK ARRAY DEGRADED / LOGICAL DRIVE CRITICAL
Disk arrays are made up of physical drives. Logical drives are created on the disk array.
When one of the physical drives in a disk array fails:
• The operational status of the disk array becomes Critical.
- The operational status of the logical drives becomes Critical or Degraded.
- The operational status of the physical drive becomes Dead or Offline.
WebPAM PROe reports these conditions in the following places:
- Dashboard tab
A yellow ! icon beside the disk arrays, logical drives, and physical drives under System Status.
Major event for the logical drive under Event Information.
Warning event for the physical drive under Event Information.
- Device tab
Front View – Physical drives are shown Dead or Offline and marked with a red X icon, or Missing.
Physical Drive View – Physical drives are shown Dead or Offline and marked with a red X icon, or Missing.
- Storage tab
Disk Array and Logical Drive are marked Critical with a yellow ! icon.
RAID 6 and 60 logical drives are marked:
- Degraded with a yellow ! icon when ONE physical drive is offline.
• Critical with a yellow ! icon when TWO physical drives are offline.
RAID 0 logical drives show Offline status and a red X icon.
If there is no spare drive or unconfigured drive in the RAID system, you must provide the replacement drive. See "Installing Physical Drives" on page 35.
- Administration tab
Depending on your settings and availability of a replacement drive, your system automatically rebuilds the degraded disk array. See "Rebuilding a Disk Array" on page 636.
The system sends an Email message about the incident to subscribing users, depending on user settings. See "Setting User Event Subscriptions" on page 141.
Disk arrays are made up of physical drives. Logical drives are created on the disk array. When a disk array and its logical drives go Offline, the data stored in the logical drives is no longer accessible.
RAID 0 logical drives go Offline when ONE physical drive is removed or fails.
RAID 1, 1E, 5, 10, and 50 logical drives go Offline when TWO physical drives are removed or fail.
RAID 6 and 60 logical drives go Offline when THREE physical drives are re-moved or fail.
WebPAM PROe reports these conditions in the following places:
- Dashboard tab
A red X icon appears beside the disk arrays, logical drives, and physical drives under System Status.
Major event for the logical drive under Event Information
Warning event for the physical drive under Event Information.
- Device tab
On Front View and Physical Drive View, physical drives are shown Dead, Offline, or Missing.
- Storage tab
Disk array and logical drives are marked with a red X icon.
- Administration tab
Under Background Activities, no Rebuild takes place. See "Repairing an Offline Disk Array or Logical Drive",
below.
The system sends an Email message about the incident to subscribing users, depending on user settings. See "Setting User Event Subscriptions" on page 141.
REPAIRING AN OFFLINE DISK ARRAY OR LOGICAL DRIVE
RAID 1, 1E, 5, 6, 10, 50, and 60 Logical Drives
If a fault-tolerant logical drive, RAID 1, 1E, 5, 6, 10, 50, and 60, goes Offline, it may be possible to recover your data.
Warning
Take no further corrective action until you have consulted with Technical Support!
RAID 0 Logical Drives
If a logical drive based on a non-fault-tolerant disk array, RAID 0, goes offline, all of the data on the logical drive is lost.
To recreate your logical drive:
- Identify the failed physical drive. See "Locating a Physical Drive" on page 185.
- Replace the failed drive. See "Installing Physical Drives" on page 35.
- If the disk array had more than one physical drive, delete the disk array and re-create it.
See "Deleting a Disk Array" on page 192 and "Creating a Disk Array Manually" on page 190. - Restore the data from your backup source.
REBUILDING A DISK ARRAY
When you rebuild a disk array, you are actually rebuilding the data on one physical drive.
- When a physical drive in a disk array fails and a spare drive of adequate capacity is available, the disk array begins to rebuild automatically using the spare drive.
- If there is no spare drive of adequate capacity, but the Auto Rebuild function is ENABLED, the disk array begins to rebuild automatically as soon as you remove the failed physical drive and install an unconfigured physical drive in the same slot. See “Making Rebuild Settings” on page 153.
- If there is no spare drive of adequate capacity and the Auto Rebuild function is DISABLED, you must replace the failed drive with an unconfigured physical drive, then perform a Manual Rebuild. See "Rebuilding a Disk Array" on page 196.
Important
If your replacement disk drive was formerly part of a different disk array or logical drive, you must clear the configuration data on the replacement drive before you use it. See "Clearing a Stale or a PFA Condition" on page 187.
INCOMPLETE ARRAY
A more serious, but far less common problem is an Incomplete Array. An in-complete array results from a physical drive that fails or becomes missing during:
• RAID level migration
- Disk array transport
Migration
Normally, if a physical drive or the controller fails during migration, the disk array goes critical, and you can rebuild it.
Transport
Transport is the action of moving the physical drives of a disk array:
• To different slots in the same enclosure
• From one enclosure to another
If a physical drive fails during a transport, or you do not move all of the physical drives to their new locations, WebPAM PROe displays an incomplete array. When WebPAM PROe discovers an incomplete array, it displays a dialog box asking you to:
- Click the OK button to accept the incomplete array.
- Click the Cancel button to reject the incomplete array.
Accepting an Incomplete Array
Before you accept the incomplete array, be sure all of the physical drives are present and that their drive carriers are properly installed into the enclosure. See "Installing Physical Drives" on page 35.
If you choose to accept the incomplete array:
- Click OK in the incomplete array dialog box.
- Check the operational status of the logical drives in the array.
• If the logical drives are Critical, proceed with a rebuild.
- If the logical drives are Offline, contact Technical Support. See "Contacting Technical Support" on page 666.
- Restore your data from a backup source.
If you choose NOT to accept the incomplete array:
- Click Cancel in the incomplete array dialog box.
-
Do one of the following:
-
Delete the array. This action deletes all logical drives on the array.
- Replace the missing physical drive.
CONNECTION PROBLEMS
Connection problems include:
- "Serial Connections" (below)
• "Network Connections" on page 639
• "Fibre Channel Connections" on page 640
• "SAS Connections" on page 640
- "Browser Does Not Connect to WebPAM PROe" on page 642
Connection problems cause a majority of failures in almost any electrical system. While the installation of the cables and components was correct, they don't function properly, or at all, because:
• A connector is dirty or corroded
• A connector is loose or damaged
• A cable looks OK outside but has an open circuit inside
• The wrong cable was used
The Vess R2000 ships with a full set of new cables, as required for each specific model. Be sure to use these components because: 1.) They are the proper ones for your RAID subsystem, 2.) They are in brand-new condition, and 3.) You paid for them with the purchase of your subsystem.
SERIAL CONNECTIONS
Vess uses a serial connection for the command line interface (CLI). After you set the IP address, you can access the CLI through a network connection, also. Normally, users prefer WebPAM PROe because of its graphic user interface. But the CLI can do the same jobs. And it works when your network connection is down.
For Vess, you must use the CLI to set the Management Port IP address in order for WebPAM PROe to connect with it. See "Making a Serial Connection" on page 299 and "Setting-up the Serial Connection" on page 67 for more information on making the connection. This issue is discussed further under Network Connections, below.
The CLI controls and manages but does not move data. The CLI communicates through a RJ11-to-DB9 serial data cable, supplied with the Vess. You may choose not use the CLI often and want to disconnect and store the cable. Consider leaving it connected, so you know where it is the next time you need it.
NETWORK CONNECTIONS
Each RAID controller has an Ethernet (RJ45) management port connector on the back of the enclosure. This is a 100 Mbps Ethernet connector designed to connect to your network. The Vess becomes a node on your network like any other PC, server or other component with an IP address.
Vess ships from the factory IP addresses of 10.0.0.1, 10.0.0.2, and 10.0.0.3. You must change these addresses to ones that work on your network. You make the initial IP address setting using the CLI. See "Making a Serial Connection" on page 299 and "Setting-up the Serial Connection" on page 67.
Management port connection on the RAID controller
Management Port LEDs
| State Activity | Connectivity | |
| Dark No activity | 10BaseT | |
| Steady green — 100BaseT | ||
| Flashing green Activity — | ||
Note that the virtual and maintenance ports can accept IP address assignments from a DHCP server.
If you manually assigned an IP address to the Vess R2000 but there is a DHCP server on your network, there is a chance that the server might assign the IP address to another node. You might see a warning to this effect on your PC's monitor. If this happens, WebPAM PROe may not be able to connect. See your network administrator to work out a suitable arrangement.
FIBRE CHANNEL CONNECTIONS
When there is a connection failure, use WebPAM PROe to verify that Vess sees the initiators. See “Viewing a List of FC Initiators on the Fabric” on page 230.
If Vess sees some initiators but not the one you want, the problem is most likely elsewhere in the loop or fabric. If Vess does not see any initiators:
- Check all of the Fibre Channel connections
- Verify that all nodes are properly connected and powered
- Verify that the fabric router or switch is properly connected powered
For more information, see "Managing Fibre Channel Connections" on page 227.
SAS CONNECTIONS
Faulty SAS expansion connections are suspected when the link port counter reports a large number of bad link errors.
Link errors can be caused by:
- Debris blocking the SAS cable connector
• A faulty SAS cable
• A faulty controller or I/O module SAS connector
Blocked Cable Connectors
To check for debris blocking the SAS cable connector:
- Power down the RAID subsystem and JBOD units.
- Remove the SAS cable and check all SAS connectors for debris.
- Clean the connectors as required and reconnect the SAS cable.
- Power up the subsystems and monitor the link port counter for changes in the rate of link error accumulation.
Faulty Cable
To check for a faulty SAS cable:
- Power down the RAID subsystem and JBOD units.
- Replace the SAS cable with a new one.
- Power up the subsystems and monitor the link port counter for changes in the rate of link error accumulation.
Faulty Controller or I/O Module Connector
To check for a bad controller or I/O module SAS connector:
- With the subsystems online and I/Os running, access the CLI via serial or Telnet.
See "Initial Connection" on page 206. - At the command prompt, type the following command and press Enter.
administrator@cli> sasdiag -a errorlog -l expander -e 1 -i 1 - At the command prompt, type the following command and press Enter.
administrator@cli> sasdiag -a errorlog -l c2cport
By interpreting the two error logs, you can verify which controller or I/O module SAS port is accumulating link errors.
BROWSER DOES NOT CONNECT TO WEBPAM PROE
If you successfully setup and connected to WebPAM PROe, then suddenly you can no longer connect, it might be the result of the following three conditions:
- DHCP is enabled on your Vess's virtual management port
- The DHCP server does not have a dedicated IP address for the Vess
- The Vess restarted and your DHCP server assigned a new IP address
You must obtain the new IP Address for the virtual management port in order to direct your browser to the Vess and start WebPAM PROe.
To access the new IP address:
- Start your PC's terminal VT100 or ANSI emulation program.
- Press Enter once to launch the CLI.
- At the Login prompt, type administrator and press Enter.
- At the Password prompt, type password and press Enter.
- Type net and press Enter.
administrator@cli> net
| CId | Port Type | IP | Mask | Gateway | Link | |
| Virtual | Mgmt | 192.168.10.85 | 255.255.255.0 | 192.168.10.1 | Up | |
The new virtual management port IP address and other network settings display.
- Enter the new IP address into your browser to log into WebPAM PROe.
For more information, see "Making a Serial Connection" on page 299, also "Setting-up the Serial Connection" on page 67, "About IP Addresses" on page 68, and "Logging into WebPAM PROe" on page 82.
POWER CYCLING THE SUBSYSTEM
To power cycle a RAID subsystem means to:
- Shut down
- Turn off the power
- Turn on the power
- Restart
Power cycling is sometimes required as a remedial action but only when prompted by a message from software or when directed by Technical Support.
To power cycle the RAID subsystem:
- Shut down the subsystem.
When the controllers shut down, your network connection is lost. - Manually turn off the system power by pressing the power button of the RAID unit for over five seconds.
- Wait at least 10 seconds.
- Manually press the power button of the JBOD units.
- Manually press the power button of the RAID subsystem.
- Wait no less than two minutes.
-
Do one of the following actions:
-
Open your browser and log into WebPAM PROe.
- Re-establish your Telnet or SSH connection to the subsystem and open the CLU.
If you cannot log in immediately, wait 30 seconds and try again.
Important
If your RAID subsystem manages JBOD expansion units, always power on the JBOD expansion units first. Then power on the RAID subsystem.
EVENT NOTIFICATION RESPONSE

APPENDIX: USEFUL INFORMATION
The appendix covers the following topics:
• SNMP MIB Files (below)
- Adding a Second RAID Controller (page 445)
• Installing a Second RAID Controller (page 446)
SNMP MIB FILES
PROMISE supplies two MIB files to integrate the Vess R2000 subsystem into your SNMP system. These files are in the SNMP folder on the Software CD.
The MIB files are:
- FCMGMT-MIB.mib
- raidv4.mib
For help loading the MIB files, see the instructions that came with your MIB browser.
Adding a Second RAID CONTROLLER
If your Vess R2000 subsystem shipped with one RAID controller, you can add a second RAID controller. The second controller must have:
• The same firmware version as the currently installed controller
- The same amount of SDRAM as the currently installed controller
To obtain information for the currently installed RAID controller:
- Click the Device tab.
- Click the Component List icon.
- Click the Controller and click the View button.
- On the Information tab, note the Firmware Version.
- Click the Advanced information tab.
-
Note the Slot 1 and Slot 2 Memory Size.
-
Contact contact PROMISE Technical Support to order your second RAID controller.
PROMISE Technical Support prepares the new RAID controller with firmware and SDRAM to match the existing RAID controller in your Vess subsystem.
INSTALLING A SECOND RAID CONTROLLER
To install a second RAID controller in your Vess subsystem:
- Shut down the subsystem.
- Remove the blank cover from the right RAID controller slot.
- Carefully slide the new RAID controller into the slot until the handle locks in place.
-
Attach your data and management cables to the new controller, as needed. See "Making Management and Data Connections" on page 39.
-
Power up the subsystem and launch WebPAM PROe.
-
In WebPAM PROe, click the Dashboard tab and look under System Status.
-
If the new controller has a green check icon, the installation is completed. See “New Settings for Dual Controllers” on page 676
- If the new controller has a yellow ! icon, one of the RAID controllers went into maintenance mode because its firmware or memory do not match the other RAID controller. See “RAID Controller in Maintenance Mode,” below.
RAID CONTROLLER IN MAINTENANCE MODE
To manage a RAID controller in maintenance mode:
- Click the Administration tab.
- Click the Firmware Update icon.
- Click the Controller Firmware Update option.
- Compare the Firmware version on Controller 1 and Controller 2.
- If the firmware versions are different, go to "Updating Firmware on a RAID Subsystem" on page 118.
- If the firmware versions match, contact PROMISE Technical Support for help installing the correct memory into the RAID controller.
NEW SETTINGS FOR DUAL CONTROLLERS
With the second controller successfully installed, make the following settings:
- Redundancy Type – Set to Active-Active or Active-Standby.
See "Making Subsystem Settings" on page 102.
• LUN Affinity – If you choose Active-Active redundancy.
See "Making Controller Settings" on page 114
Note
The Vess subsystem boots its RAID controllers sequentially. With a second controller installed, your subsystem takes about a minute longer to boot. This condition is normal.
DUAL CONTROLLERS AND SATA DRIVES
If your Vess subsystem has SATA disk drives installed, you must install a SAS-to-SATA adapter on each of the SATA drives.
Without the SAS-to-SATA adapter, SATA drives display a red X icon and Not Usable status.
Obtain SAS-to-SATA adapters from PROMISE Technology at
http://www.promise.com.
SAS drives do not require adapters.
