Troubleshooting a SAS Controller Card . . . . . . . . . . . . . . . . . . . 234 ContentsSAS Information Update 5 This document provides information about the optional Serial-Attached SCSI (SAS) hard drives, related features, and procedures not covered in the system Installation and Troubleshooting Guide. The following topics are covered:

• Features and indicators

• Installing SAS hard drives

• SAS 2.5-inch peripheral interposer board

• Troubleshooting Features and Indicators The basic features and indicators are described in the system Installation and Troubleshooting Guide. The key changes incorporated in systems with optional SAS hard drives include the following:

• Systems with SAS drives include a SAS controller expansion card, in place of the integrated SCSI controller. SAS A and SAS B connectors on the backplane are connected to the SAS controller card.

• Systems with SAS drives include a SAS backplane for either the 3.5-inch or 2.5-inch SAS hard drives.

• RAID capability for systems with internal SAS drives is provided by the SAS controller expansion card.

• The RAID battery cable attaches to a connector on the SAS controller card, instead of to the battery connector on the system board. See Figure 1-5.

• Systems with 2.5-inch SAS hard drives have the following additional changes incorporated: – The 2.5-inch SAS backplane (see Figure 1-7) is connected to an additional board, the 2.5-inch SAS peripheral interposer board (see Figure 1-10). The interposer board provides some of the connectors included on the 3.5-inch backplane. – The control-panel cable is routed under the bay for fans 1 and 3 and connected to the back of the 2.5-inch SAS peripheral interposer board. (For 3.5-inch drives the control-panel cable connects to the front of the backplane on top of the hard drive bays.) – The cooling shroud is modified to cover the space behind the hard drive bay, and cables and other components are altered to accommodate the 2.5-inch drive bay and boards. Figure 1-1 illustrates the inside of a 2.5-inch system.6 SAS Information Update Figure 1-1. Inside the 2.5-Inch SAS System SAS Hard-Drive Indicator Codes The hard-drive carriers have two indicators—the drive-activity indicator and the drive-status indicator. See Figure 1-2. The drive-status indicator lights to indicate the status of the drive. 1 control panel 2 cooling shroud 3 memory riser card 4 expansion card slots (7) 5 fans (4) 6 diskette drive (optional) 7 optical drive (optional) 8 2.5-inch SAS hard drives (8)

5SAS Information Update 7 Figure 1-2. Hard-Drive Indicators Table 1-1 lists the drive indicator patterns for RAID hard drives. Different patterns are displayed as drive events occur in the system. For example, if a hard drive fails, the "drive failed" pattern appears. After the drive is selected for removal, the "drive being prepared for removal" pattern appears, followed by the "drive ready for insertion or removal" pattern. After the replacement drive is installed, the "drive being prepared for operation" pattern appears, followed by the "drive online" pattern. 1 drive-status indicator (green and amber) 2 green drive-activity indicator Table 1-1. Hard-Drive Indicator Patterns for RAID Condition Drive-Status Indicator Pattern Identify drive/preparing for removal Blinks green two times per second Drive ready for insertion or removal Off NOTE: The drive status indicator is also off until all hard drives are initialized after system power is applied. Drives are not ready for insertion or removal during this time. Drive predicted failure Blinks green, amber, and off. Drive failed Blinks amber four times per second. Drive rebuilding Blinks green slowly.

28 SAS Information Update Installing SAS Hard Drives This subsection describes how to install and configure SAS hard drives in the system's internal hard-drive bays. Your system features up to five 3.5-inch hard drives, or eight 2.5-inch hard drives. All drives connect to the system board through one of two optional SAS backplane boards. See "SAS Backplane Boards" on page 13 for information on these backplane options. Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays. NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the SAS RAID controller card to ensure that the host adapter is configured correctly to support hot-plug drive removal and insertion. NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS backplane boards. You may need to use different programs than those provided with the operating system to partition and format SAS hard drives. NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure. When you format a high-capacity hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9-GB hard drive, for example, can take up to 2.5 hours to format. Removing a Drive Blank NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank. The process for removing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives. For 3.5-inch hard drive configurations:

Remove the front bezel, if attached. See "Opening the System" in the Installation and Troubleshooting Guide

Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank outward from the bay.

Pry the ends of the blank outward until the blank is free. Drive online Steady green. Rebuild aborted Blinks green three seconds, amber three seconds, and off six seconds. Table 1-1. Hard-Drive Indicator Patterns for RAID (continued) Condition Drive-Status Indicator PatternSAS Information Update 9 For 2.5-inch hard drive configurations, remove the blank as you would the 2.5-inch hard drive carrier: 1 Remove the front bezel, if attached. See "Opening the System" in the Installation and Troubleshooting Guide

2 Open the drive blank release handle to release the blank. See Figure 1-3

Slide the drive blank out until it is free of the drive bay. Installing a Drive Blank The process for installing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives. For 3.5-inch hard drive configurations, the drive blank is keyed to ensure correct insertion into the drive bay. To install a 3.5-inch drive blank, insert and rotate in the keyed side of the blank into the drive bay and press evenly on the other end of the blank until it is fully inserted and latched. For 2.5-inch hard drive configurations, install the hard drive blank the same way as you install a 2.5-inch hard drive carrier: 1 Remove the front bezel, if attached. See "Opening the System" in your Installation and Troubleshooting Guide

Open the handle on the drive blank.

Insert the drive blank into the drive bay until the blank is fully seated.

Close the handle to lock the blank in place. 5 Replace the front bezel, if it was removed in step 1. Removing a Hot-Plug Hard Drive 1 Remove the front bezel, if attached. See "Opening the System" in your Installation and Troubleshooting Guide

From the RAID management software, prepare the drive for removal a nd wait until the hard-drive indicators on the drive carrier signal that the drive can be removed safely. See your SAS RAID controller documentation for information about hot-plug drive removal. If the drive has been online, the green activity/ fault indicator will flash as the drive is powered down. When both drive indicators are off, the drive is ready for removal. 3 Open the drive carrier release handle to release the drive. See Figure 1-3

Slide the hard drive out until it is free of the drive bay.

If you do not replace the hard drive, insert a drive blank in the vacated drive bay. See "Installing a Drive Blank" on page 9. NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed.10 SAS Information Update Figure 1-3. Removing and Installing a Hot-Plug Hard Drive Installing a Hot-Plug Hard Drive NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-drive carrier and attempting to lock its handle next to a partially installed carrier can damage the partially installed carrier's shield spring and make it unusable. NOTICE: Not all operating systems support hot-plug drive installation. See the documentation supplied with your operating system. 1 Remove the front bezel, if attached. See "Opening the System" in your Installation and Troubleshooting Guide

If a drive blank is present in the bay, remove it. See "Removing a Drive Blank" on page 8.
