Methodology
General Troubleshooting Methodology
There are multiple entry points to the troubleshooting process, dependent upon your level of
troubleshooting expertise, the tools, processes, and procedures which you have at your disposal,
and the nature of the system fault or failure.
1. Typically, you select from a set of symptoms, ranging from very simple, system LED is
blinking; to the most difficult, Machine Check Abort (MCA) has occurred. The following is
a list of symptom examples:
• Front Panel system LED blinking
• System Alert present on system console
• Server won’t power-up
• Server won’t boot
• Error/event message received
2. Narrow down the observed problem to the specific troubleshooting procedure required.
Isolate the failure to a specific part of the server to perform more detailed troubleshooting.
For example:
• Problem- Front Panel LED blinking
NOTE: The front panel system LED flashes amber with a warning indication, or flashes
red with a fault indication.
— System alert on system console?
— Use the system event log (SEL) to analyze the alert and identify the last error logged
by the server.
NOTE: To see the SEL, through the iLO MP text interface, use the iLO MP
commands.
3. You should have a good idea about which area of the server requires further analysis. For
example, if the symptom was “server won’t power-on”, the initial troubleshooting procedure
may have indicated a problem with the DC power rail not coming up after the power was
turned on.
