Tape Drive Technology

The DLT-S4 tape drive incorporates state-of-the-art technologies that contribute to the SDLT architecture. Some of these ideas are trademarked, others are patented. Table 2 lists some of the important technologies that comprise the DLT-S4 tape drive system.

Table 2 Tape Drive Technology

Technology	Description
Laser Guided Magnetic Recording	The DLT-S4 tape drive system is based on Quantum's Laser Guided Magnetic Recording (LGMR) technology. LGMR provides a unique combination of the best optical and magnetic technologies, which results in dramatically higher capacities by substantially increasing the number of recording tracks on the data-bearing surface of the media.
Magneto Resistive Cluster Heads	Magneto Resistive Cluster (MRC) heads are a densely packed array of small Magneto Resistive (MR) tape heads precisely positioned using advanced thin-film processing technology.
Advanced Partial Response Maximum Likelihood	Improving on Partial Response Maximum Likelihood (PRML) technology traditionally used in disk drives and communication systems, Quantum's advanced PRML channel technology, co-developed with Lucent Technologies, brings new levels of performance and capacity to high-performance linear tape products.
Advanced Metal Powder Media	Advanced Metal Powder (AMP) media is a state-of-the-art media using durable metal powder technology for recording high densities of data. The back side of AMP media receives a specially formulated coating to accept the optical servo tracks, which ensures that the entire data-bearing side of the media is available for recording data and eliminates the need for pre-formating.
Positive Engagement Tape Leader Buckling Mechanism	The positive engagement tape leader buckling mechanism engages the media leader on cartridge load and disengages it on cartridge unload. It uses a metal pin attached to the tape drive leader to link with molded clips permanently attached to the media leader inside the cartridge.

Tape Drive Components

The DLT-S4 tape drive is designed as a total system. The system includes a complex interaction of a number of important components including the base mechanical assembly, the front panel assembly (bezel), and the board assemblies. Table 3 describes these components.

Table 3 Tape Drive Components

Components	Description
Base mechanical assembly	The base mechanical assembly houses the tape control mechanical, actuator, reel motor, load mechanism, eject button, and front-panel indicators. It positions the actuator servo head over the correct tape track. It implements the functions required to buckle and unbuckle the media and control the media motion. It engages the media leader on cartridge load and disengages it on cartridge unload. • Auto load – The tape auto load is a soft-load and seating mechanism that is tolerant of forced media loading; a media sensor is triggered upon cartridge insertion, and after the media reaches a hard stop point, the auto load sensor engages, pulling the cartridges the remaining distance onto the motor. On media ejection, the assembly reverses the process and automatically ejects the cartridge a fixed distance from the front of the tape drive. • Base plate – Acts as the support platform for the other modules and for the tape drive enclosure. It also includes the mounting holes (shock mounts) used to install the tape drive into a server or tape library.
Front panel assembly (bezel)	The front panel assembly (bezel) performs these functions: • Protects the front of the drive from physical damage • Channels air flow through the system • Aligns the cartridge when it is inserted into the system • Provides label identifiers for the LEDs mounted on the front of the tape drive • Enables cartridge ejection • Reduces internal environmental contamination with a built-in dust door (internal and tabletop configurations only)
Board assemblies	The board assemblies provide the main control function for the system and the interface from the system to the host computer, library, or autoloader. This provides the Advanced Partial Response Maximum Likelihood (PRML) feature of the Quantum DLT-S technology. There are three board assemblies: • Pre-amplifier Board (PAB) – The PAB contains the preamplifier for the read heads, and the write driver for the write heads. • Motor Driver Board (MDB) – The MDB interfaces with the reel motor drivers and hall sensors, actuator driver and sensors, sensor and motor drivers for the soft load, LEDs for front-panel indicators, and eject button signals. • Drive Control Board (DCB) – The DCB is the main control card for the DLT-S4 tape drive. It sends commands to the MDB to control and drive the tape mechanism. The board interfaces with the PAB to send signals to the head for reading and writing.

Inappropriate or careless handling of DLT-S4 tape drive systems may result in damage to the product. Follow the precautions and directions to prevent damaging the DLT-S4 tape drive system. In addition, follow the steps in Pre-Installation Guidelines on page 17 to ensure that you have the correct hardware for the system configuration.

This chapter provides the following important information you need to know before you install and use your DLT-S4 tape drive:

• Warranty Note provides a general reminder of certain precautions to follow so you do not void your warranty
  Safety Precautions
• Tape Drive Handling and Storage Guidelines
• Electrostatic Discharge Protection
• Pre-Installation Guidelines describes proper steps to take before installing the tape drive in a system

Warranty Note

See the tape drive warranty before installing the tape drive; the tape drive's warranty could be voided if the installation guidelines and restrictions are not closely followed.

Generally, the Limited Product and Limited Repair Warranties are contingent upon proper use in the application for which the product is intended, and do not cover the product if you perform any of the following actions:

• Modify the product without the manufacturer's written approval
• Subject the product to unusual physical, environmental, or electrical stress, including damage caused by handling or shipping in unapproved containers or packaging
• Disturb any warranty labels, or the integrity of the product in any other way
• Remove or damage the serial number label to the extent that warranty status of the product cannot be determined

Safety Precautions

For your safety, follow all safety procedures described here and in other sections of the document.

• Turn off the system into which the DLT-S4 tape drive is to be installed or attached before installing or removing the tape drive to prevent the possibility of electrical shock or damage to the tape drive.
• Unplug the system that contains—or is to contain—the tape drive from AC power before installing the tape drive to provide an added measure of safety.

• Read, understand, and observe all label warnings.

• The DLT-S4 tape drive uses a Class I laser product. This laser product complies with 29 CFR 1200 and 29 CFR 1910 as applicable on the date of manufacture.

Warning: If you open the tape drive chassis, you may become exposed to invisible laser emission which could be harmful if you are directly exposed to the beam.

Tape Drive Handling and Storage Guidelines

Damage to the DLT-S4 tape drive system can occur as the result of careless handling, vibration, shock, or electrostatic discharge (ESD). For more details on ESD, see Electrostatic Discharge Protection on page 16.

Follow these guidelines to avoid damage to the tape drive:

Caution: Never power off the tape drive or the host while the tape drive contains a cartridge. Failure to remove a cartridge may result in cartridge or tape drive damage.

• Always handle the tape drive carefully and gently - a drop of 14 inch onto a bench or desktop can damage a tape drive.
• Hold the internal tape drive only by its sides.
• Never hold or carry the tape drive by inserting your fingers into the receiver area on the front of the tape drive. You could damage the receiver area if you lift or carry it in this manner.
• Do not bump, jar, or drop the tape drive. Use care when transporting the tape drive.
• Do not place the tape drive so that it rests on its front bezel.
• Always gently place the tape drive flat and horizontal on an appropriate ESD-protected work surface to keep the tape drive from accidentally being knocked over.

• Do not stack objects on the tape drive.

• Do not expose the tape drive to dusty, humid, or smoke-filled areas, or to excessive heat or cold (see Physical Specifications on page 38 for required temperature and humidity conditions).

• Do not place foreign objects inside the tape drive's receiver area (see figure 4).

Figure 4 Receiver Area

Electrostatic Discharge Protection

Several electrical components of the DLT-S4 tape drive system are sensitive to static electricity and electrostatic discharge (ESD). Even a static buildup or discharge that is too slight to feel can be sufficient to destroy or degrade a component's operation.

To minimize the possibility of ESD-related damage to the system, the tape drive's manufacturer strongly recommends using both a workstation anti-static mat and an ESD wrist strap. If the devices are correctly installed and properly used, they reduce the buildup of static electricity that might harm the system.

Follow these guidelines to avoid ESD damage to the tape drive:

• Use a properly fitted wrist strap or other suitable ESD protection.
• Observe proper ESD grounding techniques.

• Keep the internal tape drive in its antistatic bag until ready to install.

• Place the tape drive in the antistatic bag before placing it in a shipping container.

• Hold the internal tape drive only by its sides.
• Place the tape drive on a properly grounded anti-static work surface pad while it is out of its protective antistatic bag.
• Do not pack other materials with the tape drive in its antistatic bag.
• Do not use the bag as a substitute for the work surface antistatic pad. The outside surface of the bag may not have the same antistatic properties as the inside surface. It could actually increase the possibility of ESD problems.
• Do not remove either the tabletop tape drive cover or the internal/ library tape drive cover to use any test equipment to check components on the PCBAs. There are no user-serviceable components on the tape drive.

Pre-Installation Guidelines

Before you install the tape drive in a system, follow these steps. Also, check the tape drive to be certain it is operating properly before installing it in a system.

1 Unpack and review the contents of the box for any physical damage. If you find damaged items, contact the tape drive sales representative and the shipping company immediately.
2 Save the shipping box and packing materials in case you need to move or ship the tape drive at a later date.

Caution: When returning a unit to Quantum for repair, you must use the original or equivalent packing materials or risk voiding your warranty.

3 Record the model and serial number of the DLT-S4 tape drive system in the space provided below.

These numbers provide specific information on the DLT-S4 tape drive system and will be helpful if you must contact technical support. You can find these numbers on the bottom of the tabletop tape drive enclosure and on the top of the internal and library tape drives.

Model Number (usually begins with TC)	Serial Number (usually begins with QP, QX, or QK)

4 Check the enclosed SCSI, Fibre Channel, or SAS cable to ensure it is compatible with the SCSI, Fibre Channel, or SAS controller card in the host computer.
5 Check the SCSI, Fibre Channel, or SAS interface on the host computer to ensure that it is compatible with the tape drive (see table 5 on page 12 for a list of the possible interfaces that are available and the various options with each).
6 Confirm that your back-up software and operating system are compatible with the tape drive.

See www.quantum.com for the most up-to-date compatibility information.

Choosing Compatible Cartridges

The only cartridge the DLT-S4 tape drive can both read and write to is the DLTtape S4 cartridge.

The DLT-S4 tape drive can read from, but not write to:

Super DLTtape II cartridges formatted in the SDLT 600 tape drive
Super DLTtape I cartridges formatted in the SDLT 320 tape drive

The DLTtape S4 cartridge is black and has a distinctive pattern molded into the plastic, along with the DLTtape logo. The cartridge is made of wear-resistant materials to reduce the potential for debris generation and increase the life of the cartridge.

The cartridge's geometry is similar to previous DLTtape cartridges to simplify integration with existing tape library designs (see figure 5). Its keying feature, however, ensures that it cannot be loaded into previous generation tape drives.

Figure 5 Compatible Tape Cartridges
DLTtape S4 Data Cartridge (BLACK)

Super DLTtape II Data Cartridge (BLUE)

Super DLTape I Data Cartridge (GREEN)

Using Unsupported Cartridges

DLT-S4 tape drives are intended to be used only with the cartridges specified in Choosing Compatible Cartridges on page 19. However, Quantum DLT drives are tested with a variety of unsupported cartridges and are designed to ensure that no damage occurs to either the tape drive or the cartridge if a user attempts to use an unsupported cartridge.

If you try to insert an unsupported cartridge into the DLT-S4 drive, the drive will not be able to accept it. Possible results are:

• You may not be able to insert the unsupported cartridge into the drive.
• The unsupported cartridge may trigger the soft-load mechanism at an inappropriate time, which may cause the soft-load mechanism to stop at an improper location. While the soft-load mechanism is stopped, the unsupported cartridge may not be completely loaded in the drive, and the drive may not automatically eject the cartridge. (If this happens, you must manually eject the cartridge by issuing an EJECT command or by pressing the Eject button.)
• If the unsupported cartridge does manage to load properly, the drive will not be able to buckle, read, or write to it. If this happens, a load failure will be issued over the interface. (If this happens, you must manually eject the cartridge by issuing an EJECT command or by pressing the Eject button.)

When a compatible cartridge is loaded correctly, the left LED lights either green or orange. If you load, or attempt to load, an incompatible cartridge, the left LED stays off (see Loading a Cartridge on page 32).

Backward-read Compatibility Transfer Rate

The DLT-S4 tape drive includes a backward-read compatibility feature that enables it to read Super DLTtape I and Super DLTtape II cartridges (but not write to these cartridges). The following table lists the transfer rates for backward-read cartridges.

Table 21 Backward-read Compatibility Transfer Rates

\(Format^a\)	Cartridge Type	Native Capacity	Native Read Transfer Rate	Native Read Transfer Rate in DLT-S4 Tape \(Drive^b\)
SDLT 600	Super DLTtape II	300 GB	36.0 MB/sec	≥18.0 MB/sec
SDLT 320	Super DLTtape I	160 GB	16.0 MB/sec	≥8.0 MB/sec

a. Tape drives older than the DLT-S4 will eject a data cartridge written with DLT-S4 format.
b. Transfer rates shown are the minimum when reading uncompressed data.

Cartridge Handling and Storage Guidelines

DLTtape S4 cartridges are engineered to be reliable, robust, and durable. They are manufactured to withstand 1,000,000 head passes and have a shelf life of 30 years. By following these guidelines, you will greatly reduce the chance that you will experience problems with the cartridges or cause damage to the tape drive system.

Caution: The safety of data depends on proper care and handling of cartridges.

Caution: Never power off the tape drive while it contains a cartridge. Failure to remove a cartridge prior to power-off may result in cartridge or tape drive damage.

For best results, follow these guidelines for data cartridge handling and storage:

• Follow the handling instructions and observe the environmental specifications provided in the plastic cartridge case.
• Inspect tape cartridges for damage as described in Inspecting a Cartridge on page 25.
• Store cartridges vertically in their protective cases when not in use or when archived (see figure 6).
• Protect cartridges from shock, vibration, moisture, direct sunlight, dust, smoke, and magnetic fields.
• Do not stack more than five cartridges on top of each other.
• Do not carry cartridges loosely in a box or any other container. Allowing cartridges to jostle together exposes them to unnecessary physical shock.
• When carrying cartridges in their cases, orient the cases so that the grooves in the cases interlock. This prevents the cases from slipping apart and falling.

• Do not drop the cartridge. A dropped cartridge may have dislodged, loosened, or damaged internal components. If you drop a cartridge, give it a thorough visual inspection (see Inspecting a Cartridge on page 25 for complete instructions).

• Use only the slide-in labels provided with each cartridge or slide-in bar code labels designed for use with DLT media. Slide labels into the label slot on the cartridge (see figure 6). Never apply adhesive labels or "sticky" notes on the top, side, or bottom of tape cartridges, and do not write on the cartridge.

• Do not write on the labels with debris-producing writing instruments, such as graphite pencils and water-soluble felt pens.
• Other than the bar code label, ensure that nothing else is stuck to the cartridge before inserting it into the tape drive. Loose labels and other materials can cling to the bottom of the cartridge and get stuck in the tape drive.
• Leave unused labels attached to the printed material (called the u-card) within the cartridge case.
• Store any loose labels or other materials that are smaller than 4.5 × 4.5 inches (114.3 x 114.3 mm) separate from the cartridge. A loose label or piece of paper accidentally inserted into the tape drive along with a cartridge can prevent the hub reel and tape drive gear from meshing.
• Never touch the tape or media leader. Dust and oils from your skin contaminate the tape and affect performance.
• Avoid unnecessarily opening the cartridge media access door (see figure 9). This may expose the media to contamination or physical damage.
• Protect cartridges from shock, vibration, moisture, direct sunlight, dust, smoke, and magnetic fields. Devices that may produce magnetic fields, such as computer monitors, motors, or video equipment can alter or erase data on the media.
• Observe the proper temperature and humidity conditions for operating and storing cartridges as follows:

Temperature

Operating	10 °C to 40 °C (50 °F to 104 °F)
Storage (with data)	18 °C to 28°C (64 °F to 82 °F)

Humidity

Operating	20% to 80% non-condensing
Storage (with data)	40% to 60% non-condensing

Note: If storage or transportation of a cartridge has exposed it to temperature or humidity conditions outside the specifications shown in the preceding table, allow the cartridge to acclimate to the proper operating environment for 24 hours before using it.

Figure 6 Data Cartridge Care
Store data cartridges vertically in plastic cases

Use slide-in labels

Inspecting a Cartridge

Improper cartridge handling is the primary reason for tape drive problems. To avoid losing data or damaging the tape drive, inspect the cartridges:

• Before loading a new cartridge in the tape drive
  After dropping a cartridge or subjecting it to physical shock

• When the tape drive becomes inoperable after loading a cartridge

• When you receive a shipment of cartridges that show any sign of shipping damage

Follow these steps to inspect a tape cartridge:

1 Gently shake the cartridge and listen for loose pieces.
2 Remove the cartridge from its protective plastic case.
3 Check for loose debris attached to the cartridge, and for other contamination (oily, slimy, or sticky substances) that may have built up on the surface of the cartridge.
4 Check the cartridge for any obvious cracks or other physical damage. Rotate the cartridge in your hands, looking for broken or missing parts.
5 Rotate the cartridge to view the bottom (see figure 7).

Confirm that the spring-loaded hub on the bottom of the cartridge is centered. Press the hub to ensure that the spring is functioning properly and that the hub returns to its normal position.

Figure 7 Cartridge Bottom View

6 Check that both reel lock tabs (the small plastic tabs inside the reel lock) are partially visible (see figure 8).

One reel lock is located on the end of the cartridge that is inserted into the tape drive. The other is on the bottom of the cartridge. The reel locks are black.

Note: The reel locks can break if you drop the cartridge. If the reel lock tabs are not visible, do not use the cartridge.

Figure 8 Cartridge Reel Locks

7 Open the media access door by pressing on the tab in the door pivot notch (see figure 9). Ensure that you do not touch the media leader.

Figure 9 Opening the Media Access Door

8 Compare what you see inside the media access door to figure 10. Look for damage to the cartridge buckling clips, including:

• Bent or "toed-in" appearance on one or both clips
• Improper seating (clips should be fully retracted towards the left side of the opening)
• Bending of the leader bar that supports the clips

Figure 10 Inspecting Inside the Media Access Door

9 Examine the visible media leader (without touching it) for excessive debris, oily or sticky residue, condensed droplets of moisture, or any other signs of contamination.
10 Finally, check for proper operation of the cartridge's write-protect tab (see figure 11).

This sliding tab, located on the end of the cartridge used for the label, should snap smartly back and forth, and the orange tab should be visible when the cartridge is set to provide write protection (you cannot write over the data already on the media).

Caution: If a cartridge shows any signs of damage, do not use it. If a cartridge is dropped, retrieve the data, back it up on a new cartridge, and dispose of the dropped cartridge. A dropped cartridge should not reused even if it shows no signs of damage.

Write-protecting a Cartridge

Each cartridge has a write-protect tab, which you can use to prevent accidental erasure of data. Before inserting the cartridge into the tape drive, position the write-protect tab on the front of the cartridge (see figure 11) according to the kind of operations you expect to perform.

Note: To ensure you don't erase valuable data already written to a data cartridge, always make sure the cartridge is write-protected before inserting it into the tape drive.

Figure 11 Cartridge Write-protect Tab

• To enable write protection — Slide the write-protect tab to the left so that the bright orange rectangle is visible. This is the visual reminder that you cannot write data to the media.
  You can read existing data; however, you cannot write over existing data on the media, nor append additional data to the media.
• To disable write protection - Slide the write-protect tab to the right so that the orange rectangle is not visible.

You can write over existing data on the media, and you can append additional data to the media unless the cartridge is write-protected via firmware (in other words, the cartridge has been formatted as a DLTSage WORM cartridge; see DLTSage WORM on page 34 for details).

For more details about write-protecting a cartridge, see table 22.

Table 22 Write-protect Tab Positions

Write-protect Tab Position	Orange Write-protect Indicator	Result
Before Loading the Cartridge
Enabled (Slide tab to left)	Visible	You cannot write data to the mediaYou cannot overwrite existing data on the mediaYou cannot append additional data to the media
Disabled (Slide tab to right)	Not Visible	Unless the cartridge is write-protected via firmware:You can write data to the mediaYou can overwrite existing data on the mediaYou can append additional data to the media
After Loading the Cartridge and During Operation
If you move the write-protect tab from its right (disabled) position to its left (enabled) position	Visible	If the tape drive is currently writing to a cartridge, the write-protect feature does not take effect until after the current write operation completes.
If you move the write-protect tab from its left (enabled) position to its right (disabled) position	Not Visible	The cartridge becomes write-enabled after a variable number of seconds.

Loading a Cartridge

Follow these steps to load a cartridge (see figure 12).

1 Insert the cartridge into the receiver on the front of the tape drive.
2 Push the front center of the cartridge into the tape drive until the soft-load mechanism engages and mounts the tape.

The middle LED flashes to show that the media is loading. When the media reaches the Beginning of Tape (BOT) marker, the middle LED lights steadily.

The cartridge is now ready for use.

To verify that you have loaded a compatible cartridge, look at the left LED for the following indications.

If the Left LED is...	Then this cartridge is loaded...
Green	DLTtape S4
Orange	Super DLTtape I or Super DLTtape II
Off	No cartridge is inserted or an incompatible cartridge is inserted

For more information on choosing cartridges, see Choosing Compatible Cartridges on page 19.

Figure 12 Loading a Cartridge

Unloading a Cartridge

Follow these steps to unload a cartridge (see figure 12).

Caution:

Never turn off the tape drive or the host while the tape drive contains a cartridge. Failure to remove a cartridge prior to power-off may result in cartridge or tape drive damage.

Do NOT rush removal of the cartridge. Wait until the tape drive ejects the cartridge and the middle LED lights steady before removing the cartridge.

1 Press the Eject button (or issue an appropriate system software command).

The tape drive completes any active writing, then rewrites. The middle LED flashes as the media rewrites. When the media is finished rewinding, the tape drive ejects the cartridge and the middle LED lights steadily.

2 Remove the cartridge from the tape drive and return it to its plastic case to protect it from damage.

DLTSage WORM

DLTSage WORM is the firmware compliance management function of DLTSage. This feature uses a Write Once, Read Many (WORM) functionality, which allows you to securely archive data stored on a DLTtape S4 cartridge written on a DLT-S4 tape drive. The firmware allows you to append data to a cartridge, but you cannot rewrite, reformat, or erase the data.

DLTSage WORM firmware is a standard feature of the DLT-S4 tape drive and the DLTtape S4 cartridge. See Formatting a Cartridge as DLTSage WORM on page 35 for instructions on how to create a WORM cartridge.

DLTSage WORM Features

This section details the many features of DLTSage WORM. For more information, see

http://www.dlttape.com/technology/DLTSageWORM/index.aspx

Feature	Description
Security	The tape drive's firmware places an electronic signature key on each cartridge to ensure that data written to the media cannot be rewritten, reformatted, or erased. • The key is a unique identifier that cannot be altered. • The firmware allows you to append new data to the cartridge. • The cartridge initialization process assures that only unformatted cartridges will be WORM enabled.
Verification	The verification is a two-part process. • The DLT-S4 tape drive provides best-of-class verification through its ECC algorithms. • The firmware provides archive media verification and tamper verification with time and date signatures.
Identification	The identification applies to both the data and the cartridges. · The storage management software issues a time and date stamp, which enables you to locate and authenticate specific records using ISV compliant storage management software. · The cartridge used for DLTSage WORM is a standard DLTtape S4 cartridge. Use the special yellow labels provided by Quantum to identify the WORM cartridges.
Duplication	The data stored on the DLTape S4 cartridge can be downloaded to another storage media through any ISV-compliant storage management software.

Formatting a Cartridge as DLTSage WORM

Some backup software applications work with DLTSage to allow you to format a tape cartridge as DLTSage WORM directly via the backup software user interface.

If your backup software application does not allow this, you can use xTalk Management Console to create the DLT Sage WORM cartridge. (See xTalk Management Console on page 135 for information about xTalk Management Console.)

Follow these steps to format a cartridge with DLTSage WORM using xTalk Management Console:

1 If xTalk Mangement Console is not installed on your computer, download it now (see Accessing the Tools on page 132 for instructions on downloading).
2 Obtain a blank DLTtape S4 cartridge that you want to format as DLTsage WORM. Ensure that the cartridge contains no data.
3 Insert the cartridge into the drive and wait for the tape drive to come ready.
4 Launch xTalk Management Console.
5 Click the DLTsage WORM button on the toolbar (see figure 13).

Figure 13 DLTSage WORM Button

The DLTSage WORM Wizard displays.

6 Click Format to continue.

The cartridge is formatted as a DLT Sage WORM cartridge.

Rear Panel Connectors

This section describes how to use the rear panel connectors that are common to all models of the tape drive.

For the locations of these connectors, see the following illustrations:

SCSI- Figure 15 on page 49
- Fibre Channel - Figure 17 on page 56
SAS - Figure 20 on page 63

Power Connector Pin Assignments

Pin assignments for the 4-pin power connector are listed here. Pin 1 is indicated by a solid red dot in the illustrations.

Pin Number	Signal Name
1	+12 V DC
2	Ground (+12 V return)
3	Ground (+5 V return)
4	+5 V DC

Loader/Library Interface Connector

The connector for the library/tape drive interface is an RS-422 serial port set to 9600 baud, 8 bits per character, no parity, and 1 stop bit. All data sent to or from the library/tape drive interface consists of bit-wise encoded hex values.

This 10-pin loader connector provides the signals used when the tape drive is part of a loader/library configuration. The loader connector provides a "universal port" that can support various serial interface protocols. The electrical signals from the DLT-S4 tape drive need to be translated to the appropriate serial interface protocol by a hardware and software interface system.

The Loader/Library Controller interface conforms to the T10 Committee Automation/Drive - Transport Protocol (ADT) Specification (see www.t10.org).

The loader connector part number is Molex, 89401-1010; it is a single row, 10 × 2 ~mm configuration. See figure 14 for a schematic representation of the connector and for connector pin assignments.

For more information, see the DLT Tape Drive Library Interface Specification (6464162-xx).

This chapter provides Fibre Channel interface specifications associated with the DLT-S4 tape drive, which include the following topics:

• Rear Panel Connectors
• Fibre Channel Cable Connector
• Fibre Channel Tape Drive Features
  Practical Considerations
• Fibre Channel Speed and Topology
  World-wide Names

The Fibre Channel interface operates at transfer rates up to 4 Gb/second.

The Fibre Channel interface is ONLY available with the internal and library models; it is not available with the tabletop model.

Fibre Channel can support up to 126 devices in a loop configuration. Longwave transceivers (with fiber optic cable) support distances up to 10 kilometers; short pulsewave transceivers (with fiber optic cable) support distances up to 500 meters.

For more information on transfer rates and protocol options, see table 4 on page 11.

For more information on the Fibre Channel interface, see the DLT-S4 Interface Reference Guide (81-81281-xx).

Also, see the latest Fibre Channel reference documentation available at www.t10.org.

Rear Panel Connectors

Figure 17 shows the location of the connectors on the rear panel of the DLT-S4 Fibre Channel configured internal tape drive.

Figure 17 Fibre Channel Connectors and Jumper Block (Rear View)

Fibre Channel Cable Connector

Fibre Channel models of the DLT-S4 tape drive (internal model only) have one Fibre Channel port. The Fibre Channel cable connector looks like the one shown in figure 18.

Figure 18 Fibre Channel Cable Connector

Fibre Channel Tape Drive Features

The DLT-S4 Fibre Channel tape drive supports the following features:

Automatic speed negotiation, with transfer rates of:

1 Gb per second
2Gb per second
4 Gb per second

Automatic topology negotiation (the tape drive operates as an NL_Port or N_Port):

• Arbitrated Loop - private loop, NL_Port to NLPorts(s)
• Arbitrated Loop - public loop, NL_Port to NLPorts(s) and one FL_Port.
  Fabric attachment—N_Port to F_Port
• Point-to-Point attachment—N_Port to N_Port

FCP-2 (SCSI-3 command set) for tape devices
Class 3 level of service
Basic and extended link services
- Hard assigned port address, when attached to a library.

The library has the ability to assign a hard address to the tape drive. If no hard address is assigned to the tape drive, then a soft address is taken initially.

Practical Considerations

This section describes considerations specific to the DLT-S4 Fibre Channel tape drive.

Hot-Swappable Cables

Fibre Channel cables are "hot swappable," which means that you may connect and disconnect them with unit power turned on. Therefore, unlike some other systems, the tape drive and computer may remain powered on while you connect the DLT-S4 tape drive to the host computer.

Power Usage

DLT-S4 Fibre Channel tape drives use slightly more power than SCSI-configured tape drives. See the DLT-S4 Product Specification (81-81279-xx).

Power Cycle (Tape Drive On)

When the tape drive completes the power cycle process (including POST) and the port is initialized, the Fibre Channel port is enabled and will attempt to initialize on the attached Fibre Channel topology.

When the tape drive completes the power cycle process (tape drive turned on and POST complete), the device is on-line and capable of tape drive operations.

See Power-On Self-Test on page 113 for information about POST.

Failure to Obtain a Loop Address

If the tape drive is unable to obtain an address (fabric assigned, previously assigned, hard assigned, or soft assigned), it goes into a non-participating mode and immediately implicitly logs out all logged-in ports.

If the tape drive experiences a power-on reset, or recognizes an LIP (AL_PD, AL_PS), it does not retain a previously acquired address to use during the next loop initialization.

Fibre Channel Speed and Topology

Although Fibre Channel DLT-S4 tape drives will auto-negotiate the speed and topology, you may override the automatic selections by placing jumpers on the Fibre Channel jumper block at the rear of the tape drive.

If you decide it is necessary to change the tape drive's speed or topology, use your fingers to move the jumpers to the pattern corresponding to the speed or topology you want. Using this jumper block is optional.

Note: The tape drive only checks the jumpers at a power cycle. To change the speed or topology configurations after installation, turn off the tape drive, move the jumpers as needed, and then turn on the tape drive.

See:

Figure 17 for the Fibre Channel jumper block location
Figure 19 for the empty jumper block that you use to set the speed and topology
Table 32 and table 33 for the various jumper setting combinations

Figure 19 Fibre Channel Speed and Topology Jumper Block

	11 and 12 AND 9 and 10	Auto Topology: Tape drive attempts to • first initialize in FC Arbitrated Loop topology • then initialize in FC Point-to-Point topology

Note: Pins 1 and 2 are spare pins that are not used; there is no effect if they are jumpered or not jumpered.

World-wide Names

Each DLT-S4 tape drive contains two unique, 64-bit world-wide names: a node name for the tape drive, and one for the tape drive's Fibre Channel port. The tape drive reports the world-wide names to the host through the INQUIRY Command (12h). See the DLT-S4 Interface Reference Guide (81-81281-xx) for more information.

This chapter provides SAS interface specifications associated with the DLT-S4 tape drive, which include the following topics:

• Rear Panel Connectors
  SAS Cable Connector
  SAS Tape Drive Features
  Practical Considerations
  SAS Tape Drive Speed
  World-wide Names

The SAS interface is ONLY available with the internal and library models; it is not available with the tabletop model.

For information on transfer rates and protocol options, see table 4 on page 11.

For more information on the SAS interface, see the DLT-S4 Interface Reference Guide (81-81281-xx).

Also, see the latest SAS reference documentation available at www.t10.org.

SAS Tape Drive Features

The DLT S4 SAS tape drive supports the following features:

Automatic speed negotiation, with speeds of:
1.5 Gb per second
3 Gb per second

SAS-1.1
- Transport Layer Retries

Practical Considerations

SAS cables are "hot-swappable," meaning that you may connect and disconnect them with unit power turned on. Therefore, unlike some other systems, the tape drive and computer may remain powered on while you connect the DLT S4 tape drive to the host computer.

DLT S4 SAS tape drives use slightly more power than SCSI-configured tape drives. See the DLT-S4 Product Specification (81-81279-xx) for additional information.

SAS Tape Drive Speed

SAS DLT-S4 tape drives auto-negotiate the speed. The tape drive attempts to synchronize:

first at 3 Gb per second
then at 1.5 Gb per second

World-wide Names

Each DLT-S4 tape drive contains two unique, 64-bit world-wide names: a node name for the tape drive, and one for the tape drive's SAS port. The tape drive reports the world-wide names to the host through the INQUIRY Command (12h). See the DLT-S4 Interface Reference Guide (81-81281-xx) for more information.

Caution:

Before you begin, review the safety, ESD, and handling precautions described in Chapter 2 to avoid personal injury or damage to equipment.

Equipment Required

You need the following items to install the tape drive in a system:

Four (4) M3 x 8 mm long screws
Screwdriver
- Jumpers (supplied)
- Internal Ultra320 SCSI cable, SPI-4 (or SPI-5) compatible
Active Ultra320 SCSI terminator (if the SCSI cable is already terminated at the end then you do not need this item)

Installation Steps

To install the tape drive, perform the following tasks in this order. Each task is described in detail on the pages listed below.

Step No.	Step	Page
1	Unpack the tape drive.	Page 69
2	Set the SCSI ID.	Page 69

Rear Panel Connectors

Figure 22 shows the location of the connectors on the rear panel of the DLT-S4 SCSI configured internal tape drive.

Figure 22 SCSI Connectors and Jumpers (Rear View)

Unpacking the Tape Drive

Before you begin, clear a desk or table so that you can unpack the tape drive.

Note: If the room in which you are working differs from the temperature at which the tape drive was shipped or stored by 30^ ( 17^ ) or more, let the tape drive acclimate to the surrounding environment for at least 12 hours before opening the shipping carton.

Unpack and inspect the tape drive for shipping damage. If you notice any damage, report it both to the sales representative and to the shipping company immediately.

Caution: Save the packing materials in case you need to move or ship the tape drive in the future. When returning a unit to Quantum for repair, you must use the original or equivalent packing materials or risk voiding your warranty.

If there is no damage to the tape drive, select a server or workstation to host the tape drive, then move on to the following installation steps.

Setting the SCSI ID

Each device on the SCSI bus must have a unique SCSI ID address assigned to it. Check the SCSI IDs on all other devices on the selected server or workstation, including the SCSI host adapter, and select an unused SCSI ID for the tape drive. The factory default SCSI ID for the internal tape drive is 5 (no jumpers are installed on the jumper block). If the tape drive's factory default SCSI ID is not currently in use by another device, you do not need to change the SCSI ID.

Caution: If you reset the SCSI ID, do not use ID 7, as that ID is already in use by the SCSI host adapter.

Note: For specific recommendations for assigning SCSI IDs, refer to the system or SCSI controller documentation.

You can set the SCSI ID from 0 to 15. To change the SCSI ID, use your fingers to place the supplied jumpers on the 12-pin SCSI ID jumper block as follows:

Figure 22 shows the location of the jumper block on the rear panel of the tape drive.
Figure 23 shows the empty 12-pin jumper block that you use to set the SCSI ID.
- Table 34 shows how to place the jumpers to obtain the desired SCSI ID.

Figure 23 Detail of the Empty SCSI ID Connector

Table 34 SCSI ID Address Selections

SCSI ID Jumper Block	0	1	2	3
SCSI ID Jumper Block	4	5 (default)	6	7
SCSI ID Jumper Block	8	9	10	11
SCSI ID Jumper Block	12	13	14	15

Note: The computer system and the tape drive SCSI IDs are only checked when you turn both the computer system and the tape drive off and then on again. To change the SCSI ID after installation, turn off the system, change the tape drive's SCSI ID, and then turn on the system.

Securing the Tape Drive in the System

This section describes how to mount and secure the tape drive in the system. Because of the variety of mounting possibilities for tape drives, the instructions presented here are general guidelines. Use these instructions only as a guide for mounting the tape drive in the system.

Note: In some system configurations, it may be more convenient to connect the SCSI bus and power cables to the tape drive before securing it in the system.

Mount the tape drive in the system by performing the following steps:

1 Ensure that the host computer and all peripheral devices are turned off.
2 Position the tape drive in the system and align the tape drive mounting holes (side or bottom) with those in the system (see figure 24 and figure 25).
3 Secure the tape drive in the bay or chassis using four M3 x 8mm long screws.

Caution:

The screws used to mount the tape drive must be M3 x 8mm long. This kind of screw is exactly the proper length and will not damage the tape drive.

Figure 24 Tape Drive Mounting Holes — Right Side View

Figure 25 Tape Drive Mounting Holes — Bottom View

Connecting the Cables and Terminating the SCSI Bus

You can connect the DLT-S4 tape drive to the host computer as a single device, or as one of two total devices connected via a SCSI cable with multiple SCSI connectors in a "chain" configuration.

If you are connecting two devices to the SCSI bus, connect only one tape drive to the host computer at this time. Finish the installation procedure and confirm that the host computer and tape drive are communicating correctly (see Confirming the Installation) before adding the additional device (see Adding an Additional Device).

Follow these steps to connect the tape drive to the host computer (see SCSI Connectors and Pin Assignments on page 51 for more information).

Note: Use care when connecting the cables to avoid bending or damaging the connector pins.

1 Ensure that the tape drive, host computer, and all peripheral devices (such as printers) are turned off.

Caution: Never connect the tape drive while the tape drive, host system, or peripheral devices are turned on. Doing so could result in damage to the tape drive or other peripheral devices.

2 Disconnect any other SCSI devices from the SCSI bus at this time. You can add them back on later (see Adding an Additional Device).
3 Ensure that the SCSI cable(s) and terminator(s) are Ultra320 and SPI-4 (or SPI-5) compatible.

Note: SPI refers to SCSI Parallel Interface; you can learn more from this standard at the Web site www.t10.org.

4 Terminate the SCSI bus by making sure a terminator is installed in the very last connector of the SCSI cable.

If the SCSI cable you are using has a built-in terminator, you do not need to add another terminator (see figure 26 for an example of such a cable). If the cable is not terminated, then install an active Ultra320 SCSI terminator on the SCSI cable (see figure 27).

Note: There should be only one terminator at the end of the SCSI bus.

Figure 26 SCSI Cable with Built-in Terminator

Figure 27 SCSI Interface -Terminator Installation

5 Connect one of the SCSI connectors on the SCSI cable to the SCSI connector on the rear panel of the tape drive (see figure 28). The SCSI connectors are keyed, preventing improper connection.
6 If not already connected, connect the other end of the SCSI cable to the connector in the SCSI host adapter, aligning the colored stripe on the cable with pin 1 on the SCSI host adapter's connector.
7 Locate an available DC power cable in the host computer and attach it to the power connector on the rear panel of the tape drive (see figure 28). The connector is keyed, preventing improper connection. (See Power Connector Pin Assignments on page 46 for power pin number assignments and signal names.)
8 Check all the cable and termination connections to ensure that they are attached correctly, seated firmly, and secured.

Figure 28 SCSI and Power Cable Locations

Setting TERMPWR

At least one device on the bus must supply terminator power (TERMPRW).

• To enable TERMPWR - Install a jumper across pins 11 and 12 on the SCSI jumper block (see figure 29).
• To disable TERMPWR - Remove the jumper.

Figure 29 Enabling TERMPWR

Confirming the Installation

To confirm the installation, turn on the host computer.

The screens displayed at power-on contain:

BIOS
- Operating system
- SCSI controller information

If the first screen displays host adapter and SCSI ID information indicating the drive is a Quantum product, then the installation was successful.

If the installation was NOT successful, see POST and SCSI Troubleshooting on page 124.

Adding an Additional Device

Once you have successfully confirmed the installation of your tape drive, you may add one additional device to the SCSI bus.

Note: Use care when connecting the cables to avoid bending or damaging the connector pins.

1 Ensure that all devices have unique SCSI IDs (see Setting the SCSI ID on page 69).
2 Ensure that the tape drive, host computer, and all peripheral devices (such as printers) are turned off.

Caution: Never connect the tape drive while the tape drive, host system, or peripheral devices are turned on. Doing so could result in damage to the tape drive or other peripheral devices.

3 Make sure that all the SCSI cables and terminators are SPI-4 (or SPI-5) compatible.

4 Connect all additional tape drives and peripheral devices to the host computer's SCSI cable.
5 Ensure that a terminator is installed on the very last SCSI connector on the SCSI cable.

Note: Regardless of which device terminates the SCSI bus, that device must have power applied and be powered on for proper termination to occur.

6 Check all the cable and termination connections to ensure that they are attached correctly and seated firmly.
7 Turn on power to the system and all attached devices.
8 Confirm the installation (see Confirming the Installation on page 78).

Using the Loader/Library Interface Connector

This connector is only used for tape drives installed in loaders/libraries. If your system requires it to be used, it should have been pre-assembled at the factory. For more information about the loader/library connector, see Loader/Library Interface Connector on page 46.

Rear Panel Connectors

Figure 38 shows the location of the connectors on the rear panel of the DLT-S4 tabletop tape drive.

Figure 38 Tabletop Tape Drive — Rear View

Unpacking the Tabletop Tape Drive

Before you begin, clear a desk or table so that you can unpack the tape drive.

Note: If the room in which you are working differs from the temperature at which the tape drive was shipped or stored by 30^ ( 17^ ) or more, let the tape drive acclimate to the surrounding environment for at least 12 hours before opening the shipping carton.

Unpack and inspect the tape drive for shipping damage. If you notice any damage, report it both to the sales representative and to the shipping company immediately.

Caution: Save the packing materials in case you need to move or ship the tape drive in the future. When returning a unit to Quantum for repair, you must use the original or equivalent packing materials or risk voiding your warranty.

Selecting a Location for the Tabletop Tape Drive

Select a location for the tape drive that is flat, sturdy, level, and close to the server or workstation. There should be sufficient room for the tape drive to sit without being crowded. A desk or tabletop surface is most suitable. Regardless of the location you choose for the tape drive, make sure the environment is free from dust, cigarette smoke, and excessive temperature and humidity. See the Physical Specifications on page 38 for acceptable operating temperature and humidity limits.

Be sure to follow these additional guidelines when selecting a location for the tape drive:

• Allow at least 6 inches (15.2 cm) behind the tape drive for proper cooling.

• Avoid locations near printers or photocopy machines, both of which produce paper fiber and other types of dust and airborne contaminants.

• Do not place the tape drive on the floor.
• Avoid locations near generators, electric motors, audio speakers, or other sources of magnetic fields. Magnetic fields can adversely affect the tape drive and data cartridges.

Setting the SCSI ID

Each device connected to a SCSI bus must have a unique SDSI ID. Check the SCSI IDs on all other devices on the selected server or workstation, including the SCSI host adapter, and select an unused SCSI ID for the tape drive. The factory default SCSI ID for the tabletop tape drive is 3. If the tape drive's factory default SCSI ID is not already in use by another device on the same SCSI bus, you do not need to change the SCSI ID.

Caution: If you reset the SCSI ID, do not use ID 7, as that ID is already in use by the SCSI host adapter.

Note: For specific recommendations for assigning SCSI IDs, refer to the system or SCSI controller documentation.

You can configure the tape drive for SCSI ID addresses that range from 0 to 15 using the SCSI ID selector switch push buttons (see figure 39 for a close-up view of the SCSI ID switch and its location on the rear of the tabletop tape drive).

To change the SCSI ID, use a small screwdriver or ballpoint pen to press the buttons until the desired SCSI ID appears in the display.

To decrease the ID number - Press the button above the number.
To increase the ID number - Press the button below the number.

Figure 39 Tabletop SCSI ID Selector Switch

Connecting the Tape Drive to the Host Computer and Terminating the SCSI Bus

You can connect the DLT-S4 tape drive to the host computer as a single device, or as one of a maximum of two devices connected via SCSI cables in a "daisy chain" configuration.

If you are connecting two devices to the SCSI bus, connect only the tape drive to the host computer at this time. Finish the installation procedure and confirm that the host computer and tape drive are communicating correctly (see Confirming the Installation) before adding an additional device (see Adding an Additional Device).

Follow these steps to connect the tape drive to the host computer (see SCSI Connectors and Pin Assignments on page 51 for more information):

Note: Use care when connecting the cables to avoid bending or damaging the connector pins.

1 Ensure that the tape drive, host computer, and all peripheral devices (such as printers) are turned off.

Caution: Never connect the tape drive while the tape drive, host system, or peripheral devices are turned on. Doing so could result in damage to the tape drive or other peripheral devices.

2 Make sure that the SCSI cables and terminators are Ultra320 and SPI-4 (or SPI-5) compatible.

Note: SPI refers to SCSI Parallel Interface; you can learn more from this standard at the Web site www.t10.org.

3 Terminate the SCSI bus by attaching a SCSI terminator to either of the connectors on the rear of the tape drive (see figure 40).

Note: Regardless of which device terminates the SCSI bus, that device must have power applied and be powered on for proper termination to occur.

4 Carefully connect one end of the SCSI cable into the open SCSI connector on the rear of the tape drive (see figure 40).
5 Carefully connect the other end of the SCSI cable to the SCSI connector on the host computer (see figure 40).
6 Check all the cable and termination connections to ensure that they are attached correctly, seated firmly, and secure.

Figure 40 SCSI Chain — Single Device

Connecting the AC Power Cable

An AC power cable is supplied with each tabletop unit. The tabletop unit power supply has an auto-sensing feature; it requires no adjustment or switch setting changes for different AC sources.

To connect the AC power cable:

1 Carefully inspect the power cable and ensure that the cable is the appropriate cable for your country or region based on the following criteria.

Warning: Do not attempt to modify or use a tabletop 100-115 V AC power cable for 220-240 V AC input power. Modifying the power cable in any way can cause personal injury and severe equipment damage.

The AC power cable used with the tabletop unit must meet the following criteria:

• The power cable should be a minimum of 18/3AWG, 60^ , type SJT or SVT.

• The cable must be UL and CSA certified cordage rated for use at 250 VAC with a current rating that is at least 125% of the current rating of the product.

• You must terminate the AC plug in a grounding-type male plug designed for use in your country or region. It must also have marks showing certification by an agency acceptable in your country or region.
• The tabletop unit cable connector must be an IEC type CEE-22 female connector.
• The cable must be no longer than 4.5 meters (14.5 feet).
• The cable must be FCC compliant with emissions specifications.

See figure 41 for the AC power cable plug-end types for 115 VAC and 220 V/240 VAC usage.

Figure 41 AC Power Cable Connector Types

2 Connect one end of the AC power cable into the power connector on the rear of the tabletop tape drive (see figure 38 on page 100).
3 Connect the other end of the power cable to the AC outlet.

Confirming the Installation

To confirm the installation:

1 Turn on the DLT-S4 tabletop tape drive.
2 Turn on the host computer.

The screens displayed at power-on contain:

BIOS
- Operating system
- SCSI controller information

If the first screen displays host adapter and SCSI ID information indicating the drive is a Quantum product, then the installation was successful.

If the installation was NOT successful, see POST and SCSI Troubleshooting on page 124.

Adding an Additional Device

Once you have successfully confirmed the installation of your tape drive, you may add another device (you may have a maximum of two devices) to the SCSI bus.

Follow these steps to install the tape drive as a daisy-chain connection:

Note: Use care when connecting the cables to avoid bending or damaging the connector pins.

1 Ensure that all SCSI devices have unique SCSI IDs (see Setting the SCSI ID on page 102).

2 Ensure that the tape drive, host computer, and all peripheral devices (such as printers) are turned off.

Caution: Never connect the tape drive while the tape drive, host system, or peripheral devices are turned on. Doing so could result in damage to the tape drive or other peripheral devices.

3 Connect the SCSI cable from the host computer to the lower SCSI connector on the rear of the tape drive (see figure 42).
4 Continue the SCSI chain using the upper SCSI connector (see figure 42).
5 Make sure that all the SCSI cables and terminators are SPI-4 (or SPI-5) compatible.
6 Terminate the last device on the SCSI bus by attaching a SCSI terminator on the upper SCSI connector of the last device (see figure 42).

Note: Regardless of which device terminates the SCSI bus, that device must have power applied and be powered on for proper termination to occur.

7 Check all the cable and termination connections to ensure that they are attached correctly, seated firmly, and secure.

Figure 42 SCSI Chain — Multiple Devices

Configuring the Tape Drive

This model of tape drive is normally configured to meet customer specifications before leaving the factory, so should not require any internal configuration changes on site.

Using TERMPWR

The factory preconfigures the termination (TERMPWR) setting for the tabletop tape drive according to specific customer requirements. You cannot select TERMPWR on site.

This chapter describes how to start using the DLT-S4 tape drive system. This includes making a trial back-up, cleaning the tape mechanism, and various troubleshooting information. This chapter also includes information on the LEDs and buttons on the front panel of the system.

This chapter covers the following topics:

• Front Panel Controls and LEDs
  Power-On Self-Test
  Performing a Trial Backup
• Firmware Update via the Host Interface
• Firmware Update via the Library Tape Drive Interface
• Cleaning the Tape Drive
• Optimizing Tape Drive Performance

Front Panel Controls and LEDs

All controls and LEDs are on the tape drive's front panel (see figure 43). Use these controls and LEDs to operate the tape drive and monitor the DLT-S4 tape drive system's activities. See table 35 for a description of the front panel controls and LED functionality.

Figure 43 Tape Drive Front Panel

Left LED

On the DLT-S4 tape drive, the leftmost LED is dual color (green/orange). This LED is the Density Indicator.

• Green - A DLTtape S4 cartridge is inserted
• Orange - A Backward Read Compatible (BRC) cartridge is inserted.

Note: The DLT-S4 tape drive is backward read compatible with Super DLTtape II cartridges formatted in an SDLT 600 tape drive; and Super DLTtape I cartridges formatted in an SDLT 320 tape drive.

See table 35 for a summary of these combinations.

Front Panel Controls

Table 35 explains the function of the other LEDs and controls in the front panel.

Table 35 Interpreting Front Panel LEDs

LED/Button/Port Title	Color andSymbol	State orAction	Explanation
Left LED	Green/Orange	On(Green)	Blank or formatted DLTtape S4 cartridge inserted
		On(Orange)	·SDLT 600 tape drive formatted Super DLTtape II cartridge inserted ·SDLT 320 tape drive formatted Super DLTtape I cartridge inserted
		Off	No compatible cartridge is inserted
Middle LED	Green	Flashing	The tape drive is in use. This includes functions such as: ·The media is moving ·The tape drive is calibrating, reading, writing, or rewinding the media ·The tape drive is loading, unloading, or rewinding
		On	The tape drive is idle. There may or may not be a cartridge in the tape drive.
		Off	The tape drive has not been turned on or is not connected to a power source.
Right LED	Yellow	On	Cleaning is required. See Cleaning Instructions on page 120 for cleaning instructions.
		Off	Cleaning is not required.

Notes: Whenever the tape drive resets, all LEDs illuminate briefly and then illuminate in sequence until the reset completes (see table 36 on page 114 for a complete description). Whenever the tape drive encounters an error, all LEDs flash together.

LED/Button/Port Title	Color andSymbol	State orAction	Explanation
Eject Button	N/A	Press	Use the Eject button to eject the cartridge from the tape drive. When you press the button, the tape drive completes any active writing, then ejects the cartridge. This button also “parks” the soft-load mechanism for shipping. For instructions, see chapter 15, Preparing the Tape Drive for Shipping. See chapter 3, Cartridges for detailed cartridge handling procedures.

Notes: Whenever the tape drive resets, all LEDs illuminate briefly and then illuminate in sequence until the reset completes (see table 36 on page 114 for a complete description).
Whenever the tape drive encounters an error, all LEDs flash together.

Power-On Self-Test

The DLT-S4 tape drive system performs a self-diagnostic test, called a Power-On Self-Test (POST) each time you turn on the tape drive (see table 36). This test helps in detecting problems with the tape drive.

POST completes in approximately 10 seconds. While POST is running, the tape drive system responds BUSY to SCSI commands, but will respond to various SCSI messages.

During POST, the tape drive responds in the following ways.

If the host tries to negotiate...	The tape drive...
synchronous transfer	negotiates to asynchronous
wide transfer	negotiates to narrow

It may take longer than the duration of POST for the tape drive to become ready.

Table 36 LED Lighting Pattern During POST

Stage	What You Observe
1 (Power cycle)	·All LEDs illuminate for approximately one second.
2	·The left LED turns orange, then all LEDs turn off simultaneously.
3	This stage typically lasts 5 to 10 seconds. ·The left and right LEDs remain off. ·The middle LED flashes until POST completes.
4	When POST is complete: ·The middle LED stops flashing and remains illuminated. ·The left and right LEDs remain off.
POST failure	If POST fails: ·The middle and right LEDs illuminate steadily. ·The left LED flashes.

Note: If a cartridge is loaded when power is applied, all stages remain the same except stage 3. It may take considerably longer for stage 3 to complete because of media rewind and searching operations that occur during this stage.
If the tape drive fails POST, check for the following possible problems:
- The tape drive is not receiving adequate power (try a new power cable or a different outlet).
- The tape drive is not properly connected to the host computer and other SCSI devices.

If any of these problems exist, correct the problem, turn off the tape drive, and turn it back on to restart POST. For additional troubleshooting guidelines, see POST and SCSI Troubleshooting on page 124.

Performing a Trial Backup

Complete the following steps to perform a trial backup and verify correct tape drive installation:

1 Insert a DLTtape S4 cartridge. Push the cartridge partially into the system until the media automatically loads.
2 Choose a sample file set from the host computer.
3 Create a backup file and then restore the file set.

• If the backup file completely restores, without any errors, you installed the system correctly.
• If you experience errors, double-check the tape drive's configuration and setup (see POST and SCSI Troubleshooting on page 124).

After you have exhausted all troubleshooting alternatives, contact your service representative.

4 Press the Eject button to unload the cartridge (see figure 43 on page 111).

Note: For specific instructions on loading cartridges, see chapter 3, Cartridges.

Firmware Update via the Host Interface

When you need to update the firmware in the tape drive, you can do it either of two ways:

• Updating Firmware Using the Host Interface
• Creating a CUP/FUP Cartridge From Which to Update Firmware (used in either a manual firmware update or in a library setting)

The xTalk Management Console tool allows you to update the tape drive's firmware using the host interface, or to create a CUP/FUP cartridge for an DLT-S4 tape drive. See xTalk Management Console on page 135 for information on downloading and using xTalk Management Console.

The following subsections briefly describe both methods of updating the tape drive firmware.

Updating Firmware Using the Host Interface

Use xTalk Management Console to update the firmware:

1. Follow the instructions for downloading xTalk Management Console in xTalk Management Console on page 135.
   2 Follow the instructions in the xTalk Management Console User's Guide to download the firmware.

Creating a CUP/FUP Cartridge From Which to Update Firmware

Use xTalk Management Console to create a CUP/FUP cartridge:

1. Follow the instructions for downloading xTalk Management Console in xTalk Management Console on page 135.
   2 Follow the instructions in the xTalk Management Console User's Guide to create a CUP/FUP cartridge.

Follow these steps to use a CUP/FUP cartridge:

1 Verify that the tape drive is turned on (power is applied), and the middle LED on the front panel of the tape drive is on, but not flashing.
2 Verify that the tape drive's cartridge opening is empty. If a cartridge is in the tape drive, unload and eject it before proceeding.

3 Press and hold the Eject button for six seconds; after six seconds, the left LED begins to flash.
4 Release the Eject button, then quickly press and release the Eject button again.

At this point, the left and middle LEDs start flashing synchronously in a regular, rhythmic pattern. The tape drive is now in Firmware Upgrade mode.

You now have a "window" of 3 minutes to insert the CUP/FUP cartridge. If you do not insert a CUP/FUP cartridge and the 3-minute window expires:

• Both LEDs stop flashing, although the middle LED remains on (steadily illuminated)
• The tape drive is now out of Firmware Update mode and can be used in a normal manner (once you insert a cartridge)

To put the tape drive back in Firmware Update mode, repeat steps 2, 3, and 4.

5 Insert the CUP/FUP cartridge.

After you insert the CUP/FUP cartridge, the left and middle LEDs change their pattern and start flashing in an alternating pattern. The tape drive is now performing the firmware update.

Note: The firmware update fails the update process if the firmware personalities do not match. The history log (accessible via the LOG SENSE Page 07h) records this information, as well as the reason for the failure.

6 Wait several minutes for the update process to complete.

The left and middle LEDs flash the entire time that firmware is being updated.

When the update is complete, the tape drive resets itself and goes through POST. The tape drive rewrites the CUP/FUP cartridge, then

unloads and ejects it. SCSI status indicates that firmware has been updated (06h, 3F, 01).

Note: If the tape drive is mounted in a tape automation library, the CUP/FUP cartridge rewinds to BOT and unbuckles in preparation for unloading, but does not automatically eject. Use the applicable library command to eject the cartridge.

Firmware Update via the Library Tape Drive Interface

The DLT-S4 library tape drive interface enables you to update the firmware with a new version, or image via media update.

Follow these steps.

1 Ensure that the tape drive contains no cartridge.
2 Send the CODE UPDATE REQUEST command.
3 Send the library ATTENTION command, then check the Tape Motion Status field of the returned General Status Packet to verify the tape drive is in the Ready for Code Update (0x09) state.
4 Load the cartridge containing the new firmware into the tape drive.
5 Send the library ATTENTION command, then check the Tape Motion Status field of the returned General Status Packet to verify the cartridge is loading (0x07).
6 Send the library ATTENTION command, then check the Tape Motion Status field of the returned General Status Packet to verify the cartridge is in the CUP in Progress (0x0A) state.

Note: It takes about 1 minute to enter the CUP in Progress (0x0A) state.

7 Send the library ATTENTION command, then check the Policy Firmware Revision field to verify that the update completed successfully.

8 Unload the cartridge and remove it from the tape drive.

Caution: During the firmware update, when reprogramming the new image into the flash EEPROMs is actually in progress, a power failure (but not bus RESET) or power cycling the unit causes the controller module to be unusable. When doing a firmware update, take reasonable precautions to prevent a power failure.

Cleaning the Tape Drive

This section discusses the DLT-S4 tape drive cleaning cartridge, maintenance considerations, and important compatibility issues.

Caution: Clean the tape drive only when the backup software or right (yellow) LED light indicate cleaning is necessary (see When to Clean the Tape Drive). Use only the correct cleaning cartridge for your tape drive (see Which Cleaning Cartridge to Use).

When to Clean the Tape Drive

Quantum tape drives occasionally require preventive cleaning. To a large degree, the amount of ambient pollution and particulates in the environment dictates the cleaning frequency.

Do not clean the tape drive unless the tape drive specifically indicates that cleaning is necessary. When your backup software indicates that you need to clean the tape drive, or the right (yellow) LED on the tape drive comes on, use the cleaning cartridge to clean the unit. (See figure 43 on page 111 for the location of this LED.)

Which Cleaning Cartridge to Use

Use ONLY the SDLT CleaningTape. Other cleaning cartridges, such as CleaningTape III or DLT VS CleaningTape, are incompatible with the DLT-S4 tape drive heads.

The cleaning cartridge is packaged in a plastic case, and is white in color.

Cleaning Cartridge Life Expectancy

Each cleaning cartridge is good for 20 uses. Use one of the labels that is supplied with the cleaning cartridge to track the number of uses and discard the cleaning cartridge after the final use.

Cleaning Cartridge Compatibility

The SDLT Cleaning Tape is compatible with SDLT 220, SDLT 320, SDLT 600, and DLT-S4 tape drives.

Cleaning Instructions

To clean the tape drive, follow these steps:

Note: To use the cleaning cartridge in an autoloader or library tape drive, see the autoloader or library owner's documentation.

1 Insert a cleaning cartridge into the tape drive.

The middle (green) LED flashes and the cleaning cycle begins automatically. Based upon previous cleaning cartridge usage, the cleaning operation may last up to 10 minutes.

When the cleaning cycle completes, the tape drive automatically ejects the cleaning cartridge; turns off the right LED; and steadily illuminates the middle LED.

2 Remove the cleaning cartridge, place it back in its plastic case, and mark the label after each cleaning.

Note: On the last (20th) cleaning, the tape drive does not eject the cleaning cartridge. Press the Eject button on the front of the tape drive to eject the expired cleaning cartridge. Dispose of the expired cleaning cartridge.

Cycle Time for Cleaning Cartridge

Cycle times for cleaning cartridges are as follows.

Cycle Time	Valuea
Shortest cycle time (1st pass of cleaning cartridge)	2 minutes, 55 seconds
Longest cycle time (20th pass of cleaning cartridge)	10 minutes, 20 seconds
“Expired” cycle time (expired cleaning cartridge)	10 minutes

a. These times are accurate to ± 20 seconds.

On the last (20th) pass, the cleaning process completes and the cleaning media is rewound, but the cleaning cartridge is not ejected. You must manually eject the cartridge.

If the cleaning cartridge is loaded again after the 20th pass, it winds all the way to the end of the cartridge and back again without performing the cleaning sequence, and the cleaning cartridge does not eject. You must manually eject the cartridge.

Optimizing Tape Drive Performance

Many factors contribute to tape drive performance. Host system considerations include processor speed, block size, host adapter performance, host bus configurations, and software.

If you are concerned about the performance of the tape drive, check the following:

• Ensure that the tape drive is properly defined for the host system. If the tape drive is not defined within the system, the host adapter does not interact well with the tape drive.

• Ensure that the host bus adapter card and the SCSI bus are operating in Ultra320 mode.

• Check the host block size.

The DLT-S4 tape drive supports block sizes up to 16 MB. In general, the larger the block size, the better the throughput. Many older software applications default to a 512-byte block size, which results in poor performance.

• Ensure that you are using a cartridge that is compatible with the tape drive.

Chapter 14 Troubleshooting

This chapter lists troubleshooting tips and diagnostic tools to use if the tape drive system fails or you experience poor performance. This chapter covers:

General Troubleshooting
POST and SCSI Troubleshooting
Over Temperature Condition

For complete inspection instructions for DLTtape S4, Super DLTtape II, and Super DLTtape I cartridges, see chapter 3, Cartridges.

The Web site wwwquantum.com also includes valuable information on DLT systems.

General Troubleshooting

Follow these steps to troubleshoot problems with the DLT-S4 tape drive:

1 Visually inspect the cartridge for damage, and try a new cartridge if necessary (see chapter 3, Cartridges).
2 Ensure that the cables and connectors are in good working condition. For example, check that they are not worn or broken, and there are no missing or bent pins.

3 Ensure that the connector on each end of the cable is fully seated.
4 Disconnect the tape drive from the host system, turn off the tape drive, and turn it on again to perform a POST (see Power-On Self-Test on page 113).
5 If you have a SCSI tape drive--remove all devices from the SCSI bus. Connect the tape drive directly to the host computer and terminate it (see Connecting the Cables and Terminating the SCSI Bus on page 74 for internal tape drives or Connecting the Tape Drive to the Host Computer and Terminating the SCSI Bus on page 103 for tabletop tape drives).

Confirm that the tape drive and host computer are communicating properly before adding other devices.

6 If you have a Fibre Channel tape drive – look at the rear panel to see if the Fibre Channel cable is correctly attached (see Connecting the Cables on page 86).

If the link light is illuminated, you have a working connection with the Fibre Channel network.

7 If you have a SAS tape drive -- look at the rear panel and make sure the SAS cable is correctly attached (see Connecting the Cables on page 95).
8 Ensure that the operating system (modules, patches, and drivers), backup software, and tape drive are compatible. See www.quantum.com for the most current compatibility information.

If you cannot identify or correct the problem, contact customer support (see Customer Support on page xviii for contact information). Have the model and serial number available when you call. You can find these numbers on the bottom of the tabletop tape drive enclosure and on the top of the internal and library tape drives.

POST and SCSI Troubleshooting

Table 37 provides troubleshooting tips that you will find useful in the event that the tape drive system fails its POST.

If, after attempting the recommended actions listed in the table, the problem still exists or recurs, a hardware failure may be the cause.

Contact your service representative.

Table 37 POST and SCSI
Troubleshooting Guidelines

If...	Then...	You should...
The computer does not recognize the DLT-S4 tape drive system	The computer may not be configured to recognize the interface ID.	Configure the computer to recognize the DLT-S4 tape drive system's ID.
	The SCSI ID may not be unique.	Change the SCSI ID and power cycle the entire system. The new ID becomes effective at the next power cycle or interface bus reset.
	Host bus adapter parameters may be incorrect.	Check host bus adapter documentation for parameter settings. Ensure that the host bus adapter card and the SCSI bus are operating in Ultra320 mode.
	The SCSI cable may be loose.	Ensure the SCSI cable is fully seated at each connector end.
	The SCSI bus may not be terminated correctly. A terminator may not be at the end of bus or more than two terminators may be present.	Ensure that a terminator is installed at each end of the bus (one terminator is usually already installed at the host end of the bus). If the DLT-S4 tape drive is the last or only device on the bus, be certain the terminator is installed on the DLT-S4 tape drive. If the DLT-S4 tape drive is not the last or only device on the bus, check the cable connections and ensure that the bus is properly terminated at each end.
The computer does not recognize the DLT-S4 tape drive system (continued)	The SCSI bus may be too long.	The maximum cable length for one DLT-S4 tape drive is 20 meters. The maximum SCSI cable interconnect length is 10 meters total with a maximum of two DLT-S4 tape drives on the bus.
	There may be too many devices on the SCSI bus.	• Limit the number of tape drives on SCSI bus; Quantum recommends one DLT-S4 tape drive per bus, with a maximum of two DLT-S4 tape drives per bus.
	A device may not have been turned on and a valid SCSI ID may not have been configured for that device before the system powered on and loaded BIOS.	Turn the tape drive on first, and then turn on the computer. This will enable the tape drive to be properly recognized by the system.
The tape drive does not turn on	No power is reaching the tape drive.	Check the tape drive's power cable connection at the rear of the system.
Nonfatal or fatal errors have occurred for which the cause cannot be determined	Interface bus termination or the interface cable connections may be incorrect.	• Ensure the SCSI bus is terminated and that all connections are secure, or • Ensure the Fibre Channel or SAS cables are secured at the host and drive ends.
	The AC power source grounding may be incorrect (tablet top model).	Use an AC outlet for the tabletop tape drive on the same AC line used by the host system.
The tape drive is operating more slowly than indicated in its performance specification	Your host bus adapter may be limiting the speed, or you may be using an incompatible cartridge.	·Check the host bus adapter documentation for parameter settings. ·For the best performance, make sure the SCSI controller card can operate at 320 MB/second. Limit the number of tape drives on SCSI bus; Quantum recommends one DLT-S4 tape drive per bus, with a maximum of two DLT-S4 tape drives per bus. ·Ensure that the tape drive is properly defined for the host system. If the tape drive is not defined within the system, the host adapter does not interact well with the tape drive. ·Ensure that the host bus adapter card and the SCSI bus are operating in Ultra320 mode. ·Check the host block size. The DLT-S4 tape drive supports block sizes up to 16 MB. In general, the larger the block size, the better the throughput. Many older software applications default to a 512-byte block size, which results in poor performance. ·Ensure that you are using a cartridge that is compatible with the tape drive.

Over Temperature Condition

The DLT-S4 tape drive has a thermal sensor located in the tape path. This sensor, which is used to accurately monitor the air temperature in the tape path, reacts in the following ways:

• TapeAlert occurs at 50^
• Shutdown occurs at 53^ C

SCSI status indicates the tape drive is in the over temperature condition.

For more information, see the DLT-S4 Product Specification (81-81279-xx) and the DLT-S4 Interface Reference Guide (81-81281-xx).

This chapter provides instructions on how to properly set the DLT-S4 tape drive for moving or shipping.

The DLT-S4 tape drive is equipped with a soft-load mechanism that is "parked" prior to first power-on. Upon first power-on, the soft-load mechanism becomes "un-parked" and ready for use.

If you intend to move or ship your DLT-S4 tape drive, you must "park" the soft-load mechanism. (The soft-load mechanism will automatically "unpark" upon the next power-on.)

1 Remove the cartridge from the tape drive.

Caution: Do not ship the tape drive with a cartridge loaded in it! This could cause damage to the tape drive or the tape cartridge.

2 Press and hold the Eject button for 15 seconds.

Midway through this 15-second interval, the left LED will flash orange 5 times at a frequency of once per second. After the 15-second interval, the left LED will flash green at a much higher frequency.

3 Release the Eject button.
4 Within 10 seconds, press and release the Eject button once.

The soft-load mechanism will "park" and the Left LED will flash green at a frequency of once per second to verify the "parking" operation is complete.

5 Power off the tape drive.

It is recommended that you retain and re-use the original packaging materials if you plan to ship your DLT-S4 tape drive.

Quantum frequently provides new and updated tools to use with its tape drives. These tools include such items as upgrades for product software and firmware, and diagnostic software that may be newly developed.

These tools either come standard on the DLT-S4 firmware, or can be downloaded from the Quantum Web site (see Accessing the Tools on page 132 for instructions). New tools and utilities get added frequently, so check the site often.

The tools discussed in this chapter are:

Device Drivers

Quantum offers device drivers for:

• Windows® 2000
• Windows XP®
• Windows Server™ 2003 (32-Bit Edition) - Intel x86 Platform

The Device Drivers allow for the use of all DLT tape drives with Windows 2000, Windows XP, and Windows Server 2003 running on Intel x86 (32-bit) platforms.

TapeAlert

DLT-S4 tape drives are delivered with TapeAlert features built in. The tape drive firmware constantly monitors the device's hardware and media, checking for errors and potential difficulties. It flags any problems identified on the SCSI LOG SENSE Page 2Eh.

After a backup, the TapeAlert-compatible backup application automatically reads the device's TapeAlert SCSI LOG SENSE Page 2Eh to check for any problems. If an error is flagged, your backup software displays a warning message on your screen, and adds the TapeAlert messages to its logs. These messages are standard across all applications that support TapeAlert, and give an explanation of the problem and suggested resolution. For example, if you were attempting to back up to an expired cartridge, you would see the following message:

WARNING: The data cartridge has reached the end of its calculated useful life.

Copy any data you need to another cartridge.
Discard the old cartridge.

Medium Auxiliary Memory

Medium Auxiliary Memory (MAM) is a feature in the DLT-S4 tape drive that produces various attributes about the cartridge and records them on the media itself. These attributes provide the underlying information for the DLTsage suite of intelligent data protection tools.

For more information on MAM, see the DLT-S4 Interface Reference Guide (81-81281-xx).

You can view the MAM via xTalk Management Console (see xTalk Management Console on page 135).

DLTSage

DLTSage is a suite of intelligent data protection tools that enables users to more effectively manage and protect tape storage environments. Its diagnostic and monitoring tools enhances manageability by allowing you to manage and prevent problems that can occur during a routine backup.

DLTSage is a standard feature of the DLT-S4 tape drive, integrated as part of the firmware. Some of the features of DLTSage are automatically available to you when you use your backup software application. Others (such as xTalk Management Console and DLTSage Dashboard) you must download to use.

Several DLTSage applications are described in this manual:
