Running the diagnostic programs
To run the DSA Preboot diagnostic programs, complete the following steps:
1. If the server is running, turn off the server and all attached devices.
2. Turn on all attached devices; then, turn on the server.
3. When the prompt <F2> Diagnostics is displayed, press F2.
Note: The DSA Preboot diagnostic program might appear to be unresponsive
for an unusual length of time when you start the program. This is normal
operation while the program loads.
4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnostic
program.
Note: After you exit from the stand-alone memory diagnostic environment, you
must restart the server to access the stand-alone memory diagnostic
environment again.
5. Select gui to display the graphical user interface, or select cmd to display the
DSA interactive menu.
6. Follow the instructions on the screen to select the diagnostic test to run.
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.
Exception: If multiple error codes or LEDs indicate a microprocessor error, the
error might be in a microprocessor or in a microprocessor socket. See
“Microprocessor problems” on page 62 for information about diagnosing
microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try
to run the diagnostic programs again. If the problem remains, replace the
component that was being tested when the server stopped.
Diagnostic text messages
Diagnostic text messages are displayed while the tests are running. A diagnostic
text message contains one of the following results:
Passed: The test was completed without any errors.
Failed: The test detected an error.
Aborted: The test could not proceed because of the server configuration.
Viewing the test log
To view the test log when the tests are completed, type the view command in the
DSA interactive menu, or select Diagnostic Event Log in the graphical user
interface. To transfer DSA Preboot collections to an external USB device, type the
copy command in the DSA interactive menu.
