System Maintenance
•
Check for any recent changes or upgrades to the software.
For example, has anyone moved, removed, or changed the configuration files or drivers?
Refer to the software documentation for more information.

If you suspect hardware failure and there are no system error messages, check each
component associated with the failure. Equipment failure is probably the most unlikely
reason for a SCSI device failure.
A SCSI controller fails to work during initial installation.
Many SCSI controller problems are caused by an incorrect configuration rather than by faulty
hardware. Verify the SCSI controller BIOS is bannering during POST. Do the following:
1. 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 adapters except the boot
controller.
2. Make sure there are no resource conflicts.
3. For each device on the SCSI controller, verify that 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 controller (adapter board) still does not banner during POST:
1. Perform steps 1 through 3 of the pre-installation instructions listed in Chapter 4.
2. Remove the left-side cover as described in Chapter 4.
3. Reseat the SCSI controller board in its slot.
4. Reinstall the left-side cover as described in Chapter 4.
5. Reconnect the power cord.
6. Turn on the server.
If the SCSI controller still does not banner during POST:
1. Repeat steps 1 through 3 above.
2. Do the following one by one, powering up the server after each one until the SCSI
controller is bannered.
a. Move the SCSI controller board into another slot.
b. Clear CMOS. Go to Chapter 5 for detailed instructions.
c. Update the system BIOS. Go to Chapter 5 for detailed instructions.
A SCSI device fails to work after installation.
Verify that the switch settings on the SCSI device(s) are correct.
Make sure that each SCSI device is assigned a unique SCSI ID.
Ensure that no SCSI device is set to SCSI ID 7. This SCSI address is generally used by
the SCSI controller.
Check that all installed SCSI controllers are configured correctly.
