Server Stops or Hangs While Starting Up
Typically, if the HP Server hangs before the end of POST completes, the problem is possibly a hardware problem or failure. If the HP Server hangs after POST completes, the problem is possibly due to an incorrectly configured or corrupt driver, operating system, application program, or a media (disk drive) error.
If the HP Server stops working or hangs starting up:
1.Review the Troubleshooting Checklist at the beginning of the chapter before continuing.
2.Try to verify exactly where the HP Server is stopping during POST. For example: is the HP Server stopping at the memory count or on a SCSI controller? Look for any error messages and listen for any beep codes and make note of them for further assistance in troubleshooting the problem.
3.If the failure persists, verify there is not a hardware problem by running HP DiagTools.
If the problem persists, contact the HP Customer Support Center for further troubleshooting assistance.
