Installing Internal Drives
Notes:
Banks C, D, and E support hot-swap drives only.
For non-disk-array models, you might need to install an
additional SCSI-2 adapter. To order this adapter, contact
your IBM reseller or IBM marketing representative.
In a disk-array model, banks C and D or D and E can be
daisy chained or linked together into a single SCSI-2 bus
using the “daisy chain option” cable. However, the SCSI
ID jumper (J12) on one backplane must be set to HI. (See
the table under “Setting Backplane SCSI ID Jumpers
(J12)” on page 252.)
You can install up to three half-high drives or six
slim-high drives in each of banks C, D, and E.
If you have a SCSI drive in bay B, you can have up to
five drives in bank D that are connected to the same SCSI
cable. If there is no SCSI drive in bay B, you can install
up to six drives in bank D.
After the backplane is installed, you do not have to turn
off the server to install hot-swap drives in bank D.
However, you must turn off the server when performing
the steps that involve installing or removing backplanes,
cables, the fan assembly, and adapters.
