The ID of an SCSI adapter, by default, is 7. Since each device on an SCSI
bus must have a unique ID, the ID of at least one of the adapters on a shared
SCSI bus has to be changed.
The procedure to change the ID of an SCSI-2 Differential Controller is:
1. At the command prompt, enter
smit chgscsi
.
2. Select the adapter whose ID you want to change from the list presented to
you.
3. Enter the new ID (any integer from 0 to 7) for this adapter in the Adapter
card SCSI ID field. Since the device with the highest SCSI ID on a bus
gets control of the bus, set the adapter’s ID to the highest available ID. Set
the Apply change to DATABASE only field to yes.
