Troubleshooting
A SCSI Controller Does Not Work at Initial Installation
Many SCSI controller problems are caused by an incorrect configuration rather than by faulty
hardware. If the SCSI controller does not work after installation, do the following:
1. Verify the SCSI controller BIOS is bannering (displaying) on POST.
2. If more than one SCSI controller was installed, verify that each adapter is set to a
separate BIOS address or disable the BIOS on all of the other adapters except the boot
controller.
3. Be sure there are no resource conflicts.
4. For each device on the SCSI controller, check:
— Each device has a unique SCSI address.
— Do not set any device to SCSI ID 7. This is usually the controller SCSI ID.
If the SCSI banner still does not banner on POST, check the following:
NOTE: Wear an anti-static wrist guard when working inside the HP server.
1. If the SCSI controller is an adapter board:
a. Power off the HP server. Unplug the power cord from the power source and remove
the covers.
b. Reseat the SCSI controller board in its slot.
c. Replace the covers, plug the power cords back into a power source, and power on the
HP server.
2. If the SCSI controller still does not banner on POST:
a. Do all the previous to power off the HP server then move the SCSI controller board
into another slot.
b. If this still does not resolve the issue:
— Clear CMOS. (Refer to “Clearing the CMOS Configuration” in Chapter 3.)
— Flash the system BIOS. (Refer to the previous instructions in this chapter on System
BIOS Update.)
Contact the HP Customer Support Center for further troubleshooting assistance before
replacing any parts.
