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. The loading
process may take up to 10 minutes.
Step 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.
Step 5. Type gui to display the graphical user interface, or type cmd to display the DSA interactive menu.
Step 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
operation, 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 the server stops during testing and you cannot continue, restart the server and try running the DSA Preboot
diagnostic programs again. If the problem remains, replace the component that was being tested when the
server stopped.

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
Additional information concerning test failures is available in the extended diagnostic results for each test.
