Troubleshooting
For general information on HP Server products, refer to:
www.hp.com
and search for the specific product. These instructions do not generally cover third-party components or
devices. Refer to the documentation that comes with the third-party device for diagnostic and troubleshooting
information.
CAUTION
Always wear an antistatic wrist guard when working inside the HP Server.
· Ensure the HP Server is properly configured. Many HP Server problems are the result of incorrect
system and SCSI subsystem configuration settings.
· Check the system BIOS Setup Utility by pressing F2 during the boot process.
· Check the SCSI configuration or the disk array configuration by entering the controller’s setup utility.
· Boot to the Startup CD for access to configuration tools to help setup the HP Server.
· If it is a network-related error, determine if the user has enough memory and hard disk drive capacity.
Run the diagnostics for the NIC. Consult with the network operating system manual.
· If it is a hardware error, follow the instructions to log users off the LAN and power down the HP Server.
Reboot and watch for any POST error messages and listen for any beep codes as the HP Server goes
through POST then look up the error message in Chapter 5 of this Service manual. If the HP Server
passes POST, the HP DiagTools Utility can be used to further test the hardware.
· Use HP DiagTools Utility whenever possible to detect hardware problems. Insert the HP Startup CD-
ROM into the CD-ROM drive and reboot the HP Server. Run HP DiagTools from the Startup CD-ROM
and verify the Server’s hardware integrity.
· Besides HP Server DiagTools, use the standard set of tools recommended for troubleshooting:
· HP Server Assistant (NSA): This is a customizable software toolset that helps monitor and manage HP
Servers over the network from and HP OpenView console. The NSA software has a server part and a
management console, or client part.
· Toptools: HP Instant Toptools provides a set of web-based management tools that can be used to
maintain and control the HP Servers that are running Microsoft Windows 2000, Novell
NetWare/IntranetWare, or SCO UNIX.
Troubleshooting Checklist
1. Verify the error. Make sure it is not an erroneous error message. Is the error repeatable? Is the error
message seen affecting the HP Server’s operation or performance?
2. Always change only one component at a time.
3. Always check the most recently added items added, both hardware and software. Remove any third-
party components.
4. Make sure the HP Server BIOS is updated to the latest version posted to HP’s external website.
Flashing/updating the system BIOS and clearing CMOS will resolve many different issues.
5. Make sure the firmware for the hard drives are kept current. Download and run the Hard Disk Drive
Firmware Utility to verify if hard drive firmwares need to be updated. This utility is available from HP’s
external website.
6. Make sure all firmware/BIOS revisions on any controllers are kept current.
7. Use only HP-provided drivers for any HP devices used in the HP Server. This includes using HP drivers
for the initial installation of any NOS (Network Operating System) that is supported on the specific HP
Server.
8. Check all cable and power connections, including those in the rack. If the HP Server is not powering on,
unplug the AC power cords and wait 20 seconds then plug the AC power cords in again and restart the
HP Server. Check for normal operation.
