Running The Diagnostic Programs - IBM 8853L6U Service Manual

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 menu, select the test that you want to run, and follow the instructions
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 100.
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 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 "Microprocessor problems" on page 84 for information
about diagnosing microprocessor problems.
If the blade server stops responding during testing and you cannot continue, restart
the blade server and try running the diagnostic programs again. If the problem
remains, replace the component that was being tested when the blade server
stopped.
The diagnostic programs assume that a keyboard and mouse are attached to the
BladeCenter unit and that the blade server controls them. If you run the diagnostic
programs with either no mouse or a mouse attached to the BladeCenter unit that is
not controlled by the blade server, you cannot use the Next Cat and Prev Cat
buttons to select categories. All other mouse-selectable functions are available
through function keys.
To view server configuration information such as system configuration, memory
contents, interrupt request (IRQ) use, direct memory access (DMA) use, or device
drivers, select Hardware Info from the top of the screen.
