Chapter 4. Problem determination procedures for AIX and Linux This chapter outlines the procedure to follow if the server suspends operation without notice. Use the following procedure if any of the following is true: v The console displays - an SRN/SRC code - an 8-digit firmware error code - a 3- or 4-digit firmware checkpoint (progress) code v The server does not start up after installation v The server experiences an undetermined error while running, such as if the server stops running with no error code displayed Certain errors listed in the SRN/SRC table, Failing Function Code table, and Symptom-to-FRU index will also direct you to perform the diagnostic procedure based on the operating system and the type of problem. Problem determination Perform the steps in this section to perform the problem determination. Step 001 Check for the following information: 1. If a firmware checkpoint (progress) code (3 or 4 digits) is displayed, see "Firmware checkpoint (progress) codes" on page 94. 2. If a firmware error code (8 digits) is displayed, see "Firmware error codes" on page 102. 3. If you have an SRN or SRC, see "SRN tables" on page 110. 4. Check the BladeCenter management module event log. If an error was recorded by the system, see "SRN tables" on page 110. 5. Check the blade error LED on the information LED panel; if it is lit, see "Light path diagnostics LEDs" on page 145. 6. If the Blade has stalled, with no error codes and no command line or login prompt, continue to Step 002 7. If the login prompt appears and you still suspect a problem, continue to Step 002 . 8. If you have none of the above symptoms, go to "Undetermined problems" on page 156. Step 002 Perform the following steps: 1. Turn off the server, making sure to first turn off all external devices, if attached. 2. Check all cables and power cords. 3. Turn on all external devices; then, turn on the blade server. © Copyright IBM Corp. 2003 21
