Chapter 6 Troubleshooting
2. Ensure that the SCSI boot controller’s BIOS is enabled. Check this from the SCSI Setup Utility. To
access this utility, enter CTRL C when a Symbios controller banners on POST or CTRL A when an
Adaptec controller banners on POST.
3. Determine what the boot order is for the HP Server. To verify that the SCSI boot controller board is in
the correct position in the boot order, enter F2 on POST to access the system BIOS Setup Utility. The
boot order can be viewed and changed from this utility. If necessary, change the slot (if applicable) that
the SCSI controller is in to change the location in the boot order.
4. If the problem persists:
a. Clear CMOS and flash the system BIOS. See instructions previously in this chapter on the proper
procedure to do this.
b. Repeat step 3.
5. If you installed more than one SCSI controller, try disabling the BIOS on all other SCSI controller
except for the SCSI boot controller. This lets the SCSI BIOS for the boot controller load and prevents
conflicts with other SCSI controllers. If necessary, remove all the other SCSI controller boards except
the SCSI boot controller until the issue is resolved.
Contact the HP Customer Support Center for further troubleshooting assistance.
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. Make sure there are no resource conflicts.
4. For each device on the SCSI controller, check:
o Each device has a unique SCSI address.
o 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:
o Clear CMOS (See the previous instructions in this chapter on Clearing the BIOS Configuration.)
o Flash the system BIOS (See the previous instructions in this chapter on System BIOS Update.)
Contact the HP Customer Support Center for further troubleshooting assistance before replacing any parts.
A SCSI Device Stops Working
If a SCSI device stops working:
1. Verify it banners on POST or is seen in the SCSI Select Utility.
