•
Check the SCSI cables for problems that may have resulted from a recent server
maintenance, hardware upgrades, or physical damage.
•
Check the system BIOS version to ensure it is the most recently issued version. The most
recent version is listed on the HP's website.
•
Verify the SCSI BIOS is being executed properly.
The internal SCSI device controllers display a banner during startup. The BIOS then
checks for valid devices on the SCSI bus, and reports which devices are found. If the
SCSI devices are installed and configured correctly, a list confirming the devices will
banner on POST after the controller banners. If the banner is not displayed, the SCSI
controller is not recognized.
NOTE: Some tape drives do not banner on POST but will show up in the BIOS Setup Utility for the
controller and in the operating system.
•
Verify the SCSI bus is terminated at both ends.
The server's SCSI controllers in external enclosures are terminated. When a device is
connected to a connector on the SCSI bus, bus termination for that connector is disabled.
Verify the last device on the bus is terminated.
IDE problem
When an IDE device stops working:
•
Review the items under the "Troubleshooting Checklist" section earlier in this chapter.
If instructions in "Troubleshooting Checklist" section do not work, perform the following:
1. Use the Boot menu of the BIOS Setup Utility to verify that the device is enabled.
2. Use the Diagnostics for Windows utility:
•
•
3. If an accessory board was added recently or if you have changed the options on an
existing board, a resource conflict may have occurred. Resolve the conflict by doing
either of the following:
•
•
4. 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.
5. If you suspect hardware failure and there are no system error messages or beep codes,
check each component associated with the failure. Equipment failure is probably the most
unlikely reason for an IDE devices failure.
HP ProLiant ML110 Server Operations and Maintenance Guide
Verify the IDE IDs and any relevant switch settings are correct.
Verify the problem is the IDE bus by looking for specific information.
Remove the new board and restart the server.
If this corrects the problem, the board is either defective or it is trying to use a system
resource used by the IDE controller board.
Check if any of the accessory board is using memory, I/O addresses, or interrupt lines
that are also used by the IDE controller board.
