Running the DSA Preboot diagnostic programs
Use this information to run the DSA Preboot diagnostic programs.
About this task
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:
Procedure
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> 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.
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. Type
gui
to display the graphical user interface, or type
cmd
to display the
DSA interactive menu.
6. Follow the instructions on the screen to select the diagnostic test to run.
Results
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.
