Maintenance and Troubleshooting

￿￿Airborne contaminants: Sources include dust, smoke, and ashes. Steam from duplication equipment may result in intermittent disk errors.

Server Will Not Boot From a CD-ROM Disk

1.Verify the CD-ROM disk is bootable.

2.Use the BIOS Setup Utility to verify that the CD-ROM Drive is first in the boot order. To do this: o Reboot the server and run the (BIOS) Setup Utility (pressing F2).

o Scroll to the Boot menu.

o If necessary, move the CD-ROM up in the boot order list. This ensures the CD-ROM will boot before any of the hard disk drives (IDE or SCSI).

oSave and exit the Setup Utility.

If the problems persists, contact the HP Customer Support Center for further troubleshooting assistance.

SCSI Problems

The SCSI Boot Controller BIOS Has Trouble Loading The Boot Logical Drive (NOS drive)

1.Verify the SCSI boot controller is bannering (displaying) on POST.

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.
