SCSI Devices B
B.1 SCSI Tray Target IDs
The default SCSI ID numbers for devices in the SCSI tray are:
B.2 Disk Board Target IDs
Note – Default disk drive ID numbers are chosen so that IDs 4, 5, 6, and 7 are
unlikely to be assigned to disk drives. These IDs are in slots 0 and 1, which are
normally taken by a CPU/Memory board (slot 0) and an I/O board (slot 1).
The default SCSI ID numbers for disk drives located on the disk boards are
based on the board slot number as depicted in Table B-2. You can override the
default IDs by jumpers on each disk board. Each disk has an ID_ENABLE
jumper and four ID jumpers. If the ID_ENABLE jumper is not installed, the
disk drive uses the default SCSI ID. If the ID_ENABLE jumper is installed, the
disk drive uses the ID specified by the four ID jumpers located on the disk
board (an installed jumper indicates a logical 1).
