Use this information to run diagnostics, locate error codes,
and identify device errors for the blade server.
Before you perform the checkout procedure for diagnosing
hardware problems, review the following information:
- Read Safety and Installation guidelines.
- The diagnostic programs provide the primary methods of testing
the major components of the blade server. If you are not sure whether
a problem is caused by the hardware or by the software, you can use
the diagnostic programs to confirm that the hardware is working correctly.
- When you run the diagnostic programs, a single problem might cause
more than one error message. When this happens, correct the cause
of the first error message. The other error messages usually will
not occur the next time you run the diagnostic programs.
- If the blade server is halted and a POST error code is displayed,
see UEFI/POST error codes. If the blade server
is halted and no error message is displayed, see Troubleshooting tables and Solving undetermined problems.
- For intermittent problems, check the error log; see Event logs and IBM Dynamic System Analysis Preboot diagnostic program.
- If no LEDs are lit on the blade server front panel, verify the
blade server status and errors in the Advanced-Management-Module Web
interface; also see Solving undetermined problems.
- If device errors occur, see Troubleshooting tables.
