Fitting a Hard Disk Drive
There can be up to five drive modules in the subsystem, each containing
up to four drives. Each drive is fastened onto a removable drive tray. To
fit a drive:
1.
Locate an empty drive tray. It may be wise to keep a written record
of which trays are fitted with drives. You can identify a specific
drive by observing the labelling scheme as shown in the following
illustration:

Figure 3-11 Disk Subsystem Labelling Scheme
In addition to the external labelling scheme, each SCSI drive,
including the appropriate removable media drives, is assigned a
SCSI identification number. The ID scheme for each hard disk drive
module, labelled A-E, is the same. The following table indicates
these numbers:
