and ensure that different devices on the same SCSI channel do not attempt to
transfer data simultaneously. The SCSI IDs for the hard disk drives in the expansion
unit are permanent (not configurable). Table 4 lists the SCSI IDs for the hard disk
drives that are installed in the expansion unit. See “Installing a SCSI hot-swap hard
disk drive” for instructions for installing hard disk drives.

Table 4. SCSI IDs for hot-swap hard disk drives in the expansion unit

Device

SCSI ID

Drive bay 1

Drive bay 2

Note:

SCSI ID 7 is usually reserved for the SCSI controller; however, this SCSI ID
is changeable through the ServeRAID configuration program or the LSI
configuration program utility.

Use the Configuration/Setup Utility program in the blade server to enable or disable
the SCSI controller in the storage expansion unit. See the documentation that
comes with the storage expansion unit for information about configuring the storage
expansion unit and SCSI hard disk drives.

Installing a SCSI hot-swap hard disk drive

If you have installed a SCSI storage expansion unit on the blade server, you can
install up to two SCSI hot-swap hard disk drives in the bays in the expansion unit.

If a hot-swap hard disk drive in the expansion unit fails, you can replace it without
turning off the blade server. Therefore, you have the advantage of continuing to
operate the blade server while a hard disk drive in this unit is removed or installed.

Each hot-swap hard disk drive has two indicator LEDs. If the amber hard disk drive
status LED for a hard disk drive is lit continuously, that hard disk drive is faulty and
must be replaced.

Each hot-swap hard disk drive that you plan to install must be mounted in a
hot-swap-drive tray. The hard disk drive must have a Single Connector Attachment
(SCA) connector. Hot-swap-drive trays come with the hot-swap hard disk drives.

For a list of SCSI hard disk drives supported by the blade server, go to the
ServerProven list at http://www.ibm.com/pc/us/compat/.

The following illustration shows how to install a SCSI hot-swap hard disk drive.
