must change the SCSI ID of each of the remaining SCSI host bus
adapter's on the bus from the preset setting (7), to the next highest
priority remaining SCSI IDs (e.g. 6, 5, 4... and so on).
If you plan to boot your system from a hard disk drive on the SCSI
bus, you should assign that drive the next highest priority
unassigned SCSI ID. If there is only one SCSI host bus adapter
(SCSI ID = 7), the hard disk drive would be assigned a SCSI ID of
6. If there are multiple SCSI host bus adapters, the hard disk drive
would be assigned the next highest priority SCSI ID available after
all of the SCSI host bus adapters have been assigned higher
priority SCSI IDs.
The peripheral device SCSI IDs are usually set with jumpers or a
switch on the peripheral. Refer to the peripheral manufacturer's
instructions to determine the ID of each device and how to change
it.
You must have no duplication of SCSI IDs on a SCSI bus-the
system will hang or crash if duplicate SCSI IDs are on the bus.
See the “Checking SCSI Bus Compatibility” section of the Service
and User Guide for details on conforming and changing SCSI IDs.
