2.5 Setting SCSI IDs
SCSI IDs identify each SCSI device on the SCSI bus. Each SCSI ID on
a given bus must be unique. The IDs are 0 through 15 for a 16-bit bus.
The preset host adapter ID setting is 7 which gives the highest priority
to the host adapter.
If you plan to boot your computer from a SCSI hard disk drive, you must
assign SCSI ID 0 to the drive. Normally, you do not change the host
adapter SCSI ID setting from its default value.
Typically, you set the peripheral device SCSI IDs with jumpers or with a
switch on the peripheral. You must not duplicate SCSI IDs on a SCSI
bus. LSI Logic recommends that you record the SCSI IDs of all SCSI
devices.
Table 2.1 provides a place to keep this record.
