5. Perform the following steps:
Note: When possible, run AIX online diagnostics in concurrent mode. AIX online diagnostics perform
more functions than the stand-alone diagnostics.
a. Perform the AIX online diagnostics, see "Starting AIX concurrent diagnostics" on page 444. Record
any diagnostic results and see the "Service request numbers (SRNs)" on page 292 to identify the
failing component.
Note: When replacing a component, perform system verification for the component. See "Using
the diagnostics program" on page 446.
b. If you cannot perform AIX concurrent online diagnostics, continue to Step 6.
6. Perform the following steps:
a. Ensure that the device from which you load the stand-alone diagnostics is set as the first device in
the compute node boot sequence.
b. Turn off the system unit power and wait 45 seconds before proceeding.
c. Turn on the compute node and establish an SOL session.
d. Check for the following responses:
1) Progress codes are recorded in the event log.
2) Record any messages or diagnostic information that might be in the log.
e. Load the stand-alone diagnostics. Go to "Starting stand-alone diagnostics" on page 444 or
"Starting stand-alone diagnostics from a NIM server" on page 445.
f. If you have replaced the failing component, perform system verification for the component. See
"Using the diagnostics program" on page 446.
This ends the AIX procedure.
7. Perform the following steps:
a. Ensure that the device from which you load the stand-alone diagnostics is set as the first device in
the compute node boot sequence.
b. Turn off the compute node and wait 45 seconds before proceeding.
c. Turn on the compute node and establish an SOL session.
d. Check for the following responses:
1) Progress codes are recorded in the event log.
2) Record any messages or diagnostic information that might be in the log.
Continue with step 8.
8. Load the stand-alone diagnostics. Go to "Starting stand-alone diagnostics" on page 444 or "Starting
stand-alone diagnostics from a NIM server" on page 445.
Can you load the stand-alone diagnostics?
No Go to "Solving undetermined problems" on page 484.
Yes Select the resources to be tested and record any SRNs. Then go to "Service request numbers
(SRNs)" on page 292.
This ends the Linux procedure.
