Diagnostic programs, messages, and error codes
The diagnostic programs are the primary method of testing the major components
of the server. As you run the diagnostic programs, text messages and error codes
are displayed on the screen and are saved in the test log. A diagnostic text
message or error code indicates that a problem has been detected; to determine
what action you should take as a result of a message or error code, see the table in
“Diagnostic error codes” on page 45.
Running the diagnostic programs
To run the diagnostic programs, complete the following steps:
1. If the blade server is running, turn off the blade server.
2. Turn on the blade server.
3. When the prompt F2 for Diagnostics appears, press F2.
4. From the top of the screen, select either Extended or Basic .
5. From the pulldown menu, select the test that you want to run, and follow the
instructions on the screen.
For help with the diagnostic programs, press F1. You also can press F1 from within
a help screen to obtain online documentation from which you can select different
categories. To exit from the help information, press Esc.
To determine what action you should take as a result of a diagnostic text message
or error code, see the table in “Diagnostic error codes” on page 45.
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.
