HP Ultra/Wide SCSI 4 GB and 9 GB Hard Disk Drive

Step 3: Set the SCSI Address
The SCSI address is set using jumpers located on the drive. SCSI addresses range
from 0 to 15.
• Each drive is preset to SCSI address 3.
• Address 7 is reserved for communications with the SCSI host bus adapter.
• Addresses 8 to 15 should NOT be used because the HP NetServer will
time out waiting for the hard disk drive to spin up.
Set the drive to the lowest available SCSI address. Address 0 should be used for
the first drive in the system. Typically, address 1 is assigned to the second hard
disk drive, address 2 is assigned to the third drive, and so forth.
This step assumes the jumpers are accessible. If they are not accessible, it may be
necessary to remove the mounting tray or bracket to adjust the settings.
Each device on the channel needs a different SCSI address. If this is the first hard
drive in the system, complete this step to verify the jumper is set correctly. If this
is one of two or more SCSI devices in the system (and not the first drive), you
must change the SCSI address for the drive.
•
If you are connecting an Ultra/Wide SCSI drive to a narrow SCSI cable
and narrow SCSI controller, set the SCSI address to 0, 1, 2, or 3.
•
If you are connecting an Ultra/Wide SCSI drive to a wide SCSI cable and
wide SCSI controller, set the SCSI address to 0, 1, 2, 3, 4, 5, or 6.
Detailed descriptions of all the jumpers are provided in the "Jumper Settings"
appendix. Figures 1-7, 1-8, 1-9, 1-10 and 1-11 show the default SCSI address
settings for each drive.
