The first number represents the channel number and the
second is the SCSI ID. See the following illustration for
bus and SCSI ID values when option switch 1 is set to the
on state and switch 5 is on (for tower orientation). Use the
option switch on the ESM board to change the ID settings.

Notes
For IBM ServeRAID, the view configuration screens
show bay numbers, not SCSI IDs. To calculate the
bay number, add 1 to the SCSI ID.
A label is provided on the front of the drive tray. Use
this label to record the address location information for
each drive before you remove it. If you install a drive
in the wrong bay, data will be lost.
If you are replacing a drive that is part of a RAID level
1 or RAID level 5 logical drive, ensure that you install
the replacement drive in the correct bay. Failure to
replace the drives in their correct bays can result in
loss of data.
