Installation CD that comes with the BladeCenter unit. You can also get the latest version of the drivers from the IBM Support Web site at http://www.ibm.com/pc/support/. With the storage expansion unit installed on your blade server, you can install up to two hot-swap SCSI hard disk drives in the expansion unit and configure them for embedded mirroring (RAID level 1). Each SCSI device must have a unique SCSI ID. This ID enables the SCSI controller in the expansion option to identify the device 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 2 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 2. SCSI IDs for hot-swap hard disk drives in the expansion unit Device Drive bay 1 SCSI ID 0 Drive bay 2 1 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 utility program. 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 your blade server while a hard disk drive in this unit is removed or installed. Each hot-swap drive has two indicator LEDs. If the amber hard disk drive status LED for a drive is lit continuously, that drive is faulty and must be replaced. Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive tray. The drive must have a Single Connector Attachment (SCA) connector. Hot-swap-drive trays come with hot-swap drives. Chapter 4. Installing options 57

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
your
blade
server
while
a
hard
disk
drive
in
this
unit
is
removed
or
installed.
Each
hot-swap
drive
has
two
indicator
LEDs.
If
the
amber
hard
disk
drive
status
LED
for
a
drive
is
lit
continuously,
that
drive
is
faulty
and
must
be
replaced.
Each
hot-swap
drive
that
you
plan
to
install
must
be
mounted
in
a
hot-swap-drive
tray.
The
drive
must
have
a
Single
Connector
Attachment
(SCA)
connector.
Hot-swap-drive
trays
come
with
hot-swap
drives.
