Understanding SCSI SCSI IDs SCSI IDs identify each device on the SCSI bus and determine priority when two or more devices are trying to use the SCSI bus at the same time.

Understanding SCSI
SCSI IDs
SCSI IDs identify each device on the SCSI bus and determine
priority when two or more devices are trying to use the SCSI bus at
the same time. The SCSI card is also identified by a SCSI ID. For the
SCSI Card 2930CU, SCSI IDs are numbers between 0 and 7.
Adaptec presets the SCSI Card 2930CU to SCSI ID 7. You should
not change this setting. SCSI ID 7 has the highest priority on the
SCSI bus; the remaining SCSI IDs descend in priority from 6 to 0.
Use SCSI ID 0 for the first SCSI hard disk drive. Most internal SCSI
hard disk drives come from the factory set to SCSI ID 0.
Note:
If you are booting your computer from a SCSI hard disk
connected to the SCSI Card 2930CU, the Boot SCSI ID setting
in the SCSI
Select
utility must correspond to the SCSI ID of the
peripheral you are booting from. By default, the Boot SCSI ID
is set to 0. See
Boot Device Options
on page B-4
to change the
Boot SCSI ID.
Here is some general information about SCSI IDs:
■
For internal SCSI devices, you generally set the SCSI ID by
configuring a jumper on the SCSI device.
■
For external SCSI devices, you generally set the SCSI ID with a
switch on the back of the device.
■
For specific instructions on setting the SCSI ID, refer to the SCSI
device’s documentation.
■
In Windows 95/98, you can use the Device Manager to view the
SCSI ID assigned to the SCSI card and each SCSI device.
SCAM Protocol
The SCSI Card 2930CU supports the SCSI Configured
AutoMatically (SCAM) protocol. This protocol assigns SCSI IDs
dynamically and resolves SCSI ID conflicts automatically when
you start the computer. If your computer includes SCSI disk drives
or other SCSI devices that support SCAM, you do not need to
assign SCSI IDs manually to these devices.
