If you are able to restart the server or if you need comprehensive diagnostics, use DSA Preboot.

Running the DSA Preboot diagnostic programs
Use this information to run the DSA Preboot diagnostic programs.
Note:
The DSA memory test might take up to 30 minutes to run. If the problem is not a memory problem,
skip the memory test.
To run the DSA Preboot diagnostic programs, complete the following steps:
Step 1.
If the server is running, turn off the server and all attached devices.
Step 2.
Turn on all attached devices; then, turn on the server.
Step 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. 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.
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.
