Table C-2 Disk Board Default Scsi Disk Drive Id Numbers - Sun Microsystems Enterprise 6500 Reference Manual

C.2 Disk Board Target IDs
C.2.1 Default SCSI ID Numbers
The default SCSI ID numbers for disk drives on the Disk boards are listed by server
type in
TABLE C-2
Enterprise 4500 or 5500
Enterprise 6500 only
C.2.2 Overriding A Default Disk Board Target ID
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).
Note – For Enterprise 4500 and 5500 servers, 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).
