IBM 8647 - Eserver xSeries 225, Maintenance And Troubleshooting Manual

Page: 64 / 182

Note: If your server is configured for RAID operation using the integrated SCSI
controller with RAID capabilities or an optional ServeRAID controller, you
might need to reconfigure your disk arrays after installing hard disk
drives. See the ServeRAID documentation on the
IBM ServeRAID
Support CD for additional information on RAID operation and complete
instructions for using ServeRAID Manager.
6. If you are installing additional hot-swap hard disk drives, do so now; otherwise,
continue with step 7
7. Make sure that the side cover is unlocked; then, insert the hot-swap lock bar
into the slots on the front bezel and rotate it to the locked position.
8. Hold the hot-swap lock bar in the closed position, lock the side cover key lock,
and close the server door.
The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. The SCSI ID for each hot-swap hard disk drive is printed on the hot-swap
lock bar. Table 6 lists the SCSI IDs for the hard disk drives and backplane that are
connected to one channel in hot-swap hard disk drive models. In the typical
configuration, the standard hard disk drives and backplane are connected to
channel A.

Drive bay 8 1

Installing non-hot-swap hard disk drives
Bays 4, 5, and 6 are in the drive cage. The drive cage is behind the front of the
adapter-support bracket. Drives are installed starting at the bottom in bay 7.
Additional drives are then installed in bays 6, 5, and 4.
Notes:
1. You can install up to four non-hot-swap hard disk drives in your server. The
additional space in the drive cage above bay 4 is not designed to accommodate
any additional drives.
2. When installing non-hot-swap hard disk drives, you might find it easier to lay the
server on its side. If you do so, and your server has stabilizing feet that rotate,
move the feet inward toward the server, so that they do not break.
Complete the following steps to install a drive in bay 4, 5, or 6:
1. Review the safety information beginning on page 131 and “Installation
guidelines” on page 37
2. Turn off the server and all attached devices.
3. Disconnect all power cords; then, disconnect all external cables.
4. Remove the side cover (see “Removing the side cover” on page 41).
