Configuring Device IDs
The SCSI specification allows up to seven SCSI devices (and a
controller) to be connected to a single 8-bit SCSI bus. A Wide SCSI bus
can support up to 15 devices and the controller.
All SCSI devices, including the controller, must be assigned a unique
SCSI ID. SCSI IDs, which are typically set using jumpers or switches on
peripheral devices, can be assigned any number from 0 to 7 for 8-bit
SCSI devices or 0 to 15 for Wide SCSI devices.
Set the SCSI ID of each SCSI device attached to the controller to a
unique ID number between 0 and 15 (0 – 6 for 8-bit devices).
SCSI RAID controllers are set to ID 7 by default. SCSI IDs can be
duplicated on the same controller if the devices using the same ID are
not attached to the same bus.
If necessary, the SCSI RAID controller ID can be changed to any ID: 0-7.
You can use SMOR or the Configure Host Bus Adapter dialog in
Storage Manager to change the controller SCSI ID.
Note:
Changing the controller ID is not recommended. You
should leave the Adaptec controller at SCSI ID 7 unless your
configuration requires unique controller IDs.
