Running the 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 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> Dynamic System Analysis is displayed, press F2.
4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnostic
5. Type gui to display the graphical user interface, or type cmd to display the DSA
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.
Exception: If multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See "Microprocessor problems" on page 92 for information about diagnosing
microprocessor problems.
