Configuring Device IDs
The SCSI specification allows up to 7 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.
SCSI
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 6. The SmartRAID VI controller is set
to ID 7 by default (most SCSI controllers use ID 7). Wide SCSI devices
can also use SCSI IDs 8 through 15. 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 SmartRAID controller ID can be changed to any ID
0 – 7. You can use SMOR or the Configure Host Bus Adapter window in
Storage Manager to change the controller SCSI ID.
NOTE
Changing the controller ID is not recommended. You should
leave the SmartRAID VI controller at SCSI ID 7.
Fibre Channel
Fibre Channel controllers and their attached Fibre Channel devices are
configured automatically during boot. Device IDs are assigned within
the range 0 – 126 and cannot be changed manually.
