3. If the AIX operating system records a service request number (SRN), see “Service request
numbers (SRNs)” on page 129.
4. Check the BladeCenter management-module event log. If an error was recorded by the
system, see “POST progress codes (checkpoints)” on page 84 or “System reference codes
(SRCs)” on page 16.
5. If no error was recorded, or if the login prompt appears and you still suspect a problem,
continue to Step 003.
Step 003
Is the operating system AIX?
Yes Record any information or messages that may be in the management module event log;
then go to Step 005.
No Go to Step 004.
Step 004
Is the operating system Linux?
Yes Record any information or messages that may be in the management module event log;
then go to Step 007. If you cannot load the stand-alone Diagnostics CD, answer this
question No.
No Go to “Solving undetermined problems” on page 227.
Step 005
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.
1. Perform the AIX online diagnostics, see “Starting AIX concurrent diagnostics” on page 186.
Record any diagnostic results and see the “Service request numbers (SRNs)” on page 129 to
identify the failing component.
Note: When replacing a component, perform system verification for the component. See
“Using the diagnostics program” on page 189.
2. If you cannot perform AIX concurrent online diagnostics, continue to Step 006.
Step 006
Perform the following steps:
1. Use the management-module Web interface to make sure that the device from which you load
the stand-alone diagnostics is set as the first device in the blade server boot sequence.
2. Turn off the system unit power and wait 45 seconds before proceeding.
3. Turn on the blade server and establish an SOL session.
4. Check for the following responses:
a. Progress codes are recorded in the management-module event log.
b. Record any messages or diagnostic information that might be in the log.
5. Load the stand-alone diagnostics. Go to “Starting stand-alone diagnostics from a CD” on page
187 or “Starting stand-alone diagnostics from a NIM server” on page 188.
6. If you have replaced the failing component, perform system verification for the component.
See “Using the diagnostics program” on page 189
This ends the AIX procedure.
Step 007
Perform the following steps:
1. Use the management-module Web interface to make sure that the device from which you load
the stand-alone diagnostics is set as the first device in the blade server boot sequence.
