Installing the LSIU160
2.2.7
Setting SCSI IDs
You must set each SCSI device and the host adapter to a separate SCSI
ID 0 through 15. SCSI ID 7 is the preset host adapter setting, giving it
the highest priority on the SCSI bus. If you plan to boot your computer
from a SCSI hard disk drive on the SCSI bus, that drive should have the
lowest SCSI ID on the bus. Typically, SCSI ID 0 is used; however, for
system performance optimization, an ID other than 0 (zero) can be used.
Chapter 3, “Configuring the LSIU160,”
explains how to set the host
adapter ID using the LSI Logic SCSI BIOS Configuration Utility.
The peripheral device SCSI IDs are usually set with jumpers or with a
switch on the peripheral. Refer to the peripheral manufacturer’s
instructions and to the user’s manual for your computer to determine the
ID of each device and how to change it.
Note:
You must not have any duplication of SCSI IDs on a SCSI
bus.
Step 1.
Determine the SCSI ID of each device on the SCSI bus. Note
any duplications.
Step 2.
Make any necessary changes to the SCSI IDs to eliminate
duplicates and record the IDs for future reference.
