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 messages.

Running the diagnostic programs

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 Press F2 for Dynamic System Analysis (DSA) 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.
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.
5. Select gui to display the graphical user interface, or select cmd to display the DSA interactive menu.
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
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 multiple error codes or EasyLED diagnostics LEDs indicate a microprocessor error, the error might be in a
microprocessor or in a microprocessor socket. See "Microprocessor problems" on page 62 for information
about diagnosing microprocessor problems.
