SCSI IDs for hot-swap hard disk drives
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. The following table 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.
