NOTE: The Front Panel Health LEDs will be flashing amber with a warning indication, or flashing red with a fault indication.

—System Alert on console?

—Analyze the alert by using the system event log (SEL), to identify the last error logged by the server. Use the iLO 2 MP commands to view the SEL, using either the iLO 2 MP’s serial text interface, telnet, SSH, or web GUI on the iLO 2 MP LAN.

At this point, you will have a good idea about which area of the system requires further analysis. For example, if the symptom was “system will not power on”, the initial troubleshooting procedure may have indicated a problem with the dc power rail not coming up after the power switch was turned on.

You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) has been identified and needs to be replaced. You must now perform the specific removal and replacement procedure, and verification steps. See Chapter 6: “Removing and Replacing Server Components” (page 177) for information.

NOTE: If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed unless all identified failed FRUs are replaced.

There may be specific recovery procedures you must perform to finish the repair. For example, if the core I/O board FRU is replaced, restore customer specific information.

NOTE: Always check the iLO 2 MP system event logs (SEL) in the case of a blinking yellow or red front panel LED, before replacing any hardware.

NOTE: For system level 3-5 alerts, the attention condition on the system LED can be cleared by accessing the logs using the sl command, available in the MP Main Menu. To access the iLO 2 MP from the console serial port, enter Control+B or ESC-( .

Recommended Troubleshooting Methodology

The recommended methodology for troubleshooting a server error or fault is as follows:

1.Consult the system console for any messages, emails, or other information, pertaining to the server error or fault.

2.View the front panel LEDs (Power, External Health, Internal Health, and System Health), either locally, or remotely using the iLO 2 MP vfp command.

3.Compare the state of the server LEDs (off; flashing or steady; Red, Green, or Amber) with the LED states listed in Table 5-2.

4.Go to the step number of Table 5-3, specified in the rightmost column of Table 5-2, located in the row which corresponds to your front panel LED display state.

5.Read the symptom and condition information in the leftmost column of Table 5-3.

6.Perform the action(s) specified in the “Action” column.

7.If more details are required, see the appropriate subsection of this chapter, where this information is provided in the Action column. The action you are directed to perform may be to access and read one or more error logs (such as, Event Log and/or Forward Progress Log).

While we do suggest that all users follow the recommended troubleshooting methodology, and use the Basic and Advanced Troubleshooting Tables in the next subsection, as a more experienced troubleshooter you may elect to go directly to the subsection of this chapter (or section of this manual) which corresponds to your own entry point of choice. Table 5-1provides the corresponding subsection or location title for these different entry points (for example, if you
