HP Integrity rx3600 Server User Service Guide

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
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 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 161) 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 39.
4. Go to the step number of Table 40, specified in the rightmost column of Table 39, 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 40.
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 38 provides the corresponding
