5. When the boot prompt appears, press enter, type dsa and press enter again.
Alternatively you can wait for the timeout to expire.
6. The command line interface prompt will then appear on the SOL connection.
The BladeCenter QS21 does not support the graphical user interface.
7. Follow the on screen directions to run preboot DSA. Diagnostics are run from
within preboot DSA.
When you are using the CPU or Memory stress tests, call your IBM service
representative if you experience any system instability.
To determine what action you should take as a result of a diagnostic text message,
see “DSA error messages.”
Open firmware memory diagnostic results are output to the SOL connection. They
are also logged in NVRAM. All NVRAM logs (more than just OF diags) are collected
as part of the DSA merged log.
If the diagnostic programs do not detect any hardware errors but the problem
remains during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with your software.
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 there are multiple error codes or light path diagnostics LEDs that indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See Table 20 on page 90 for further information about diagnosing
microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try
running the diagnostic programs again.
Diagnostic text messages
Diagnostic text messages are displayed while the tests are running. A diagnostic
text message contains one of the following results:
v
Passed : The test was completed without any errors
v Failed : The test detected an error
v
Aborted : The test could not proceed because of the server configuration
Additional information concerning test failures is available in the extended
diagnostic results for each test.
Viewing the test log
To view the test log when the tests are completed, issue the view command from
the DSA command line interface. DSA collections may also be transferred to an
external USB device using the copy command from the DSA command line
interface.
DSA error messages
The tables below describe the messages that the diagnostic programs might
generate and suggested actions to correct the detected problems. Follow the
suggested actions in the order given.
