Methodology

General Troubleshooting Methodology

There are multiple entry points to the troubleshooting process, depending on your level of troubleshooting expertise; the tools, processes, and procedures available, and the type of system fault or failure.

Typically, you select from a set of symptoms, ranging from very simple (System LED is blinking) to the most difficult (Machine Check Abort, for example, MCA, has occurred). The following is a list of symptom examples:

•Front Panel LED blinking

•System Alert present on console

•System will not power on

•System will not boot

•Error or event message received

•Machine Check Abort (MCA) occurred

Next, you narrow down the observed problem to isolate the failure to a specific part of the server, so that you can perform more detailed troubleshooting. For example:

•Problem- Front Panel LED blinking
