Specifications

If the LEDs and SEL do not give you enough information for you to identify the issue you are
experiencing, HP also provides diagnostic tools with each operating system (see “Troubleshooting
tools” (page 64) for more details).
NOTE: Always check the iLO MP SEL in the case of a blinking yellow or red front panel health
LED, before replacing any hardware.
Executing recommended troubleshooting methodology
The recommended methodology for troubleshooting a server blade error or fault is as follows:
1. Consult the system console for any messages, emails, and so on, pertaining to a server blade
error or fault.
2. View the front panel LEDs (power and health), locally or remotely through the iLO MP vfp
command.
3. Read the symptom/condition information in the left column of Table 5-2 (page 61).
4. Perform the actions specified in the Action column.
For more details, see the appropriate subsection of this chapter, where this information is provided
in the Action column. The Action you are directed to perform might be to access and read one
or more error logs (the event log and/or the FPL).
You can follow the recommended troubleshooting methodology, and use Table 5-2 and Table 5-3
(page 63) or go directly to the subsection of this chapter which corresponds to your own entry
point. Table 5-1 provides the corresponding subsection or location title for these different entry
points (for example, to start by examining the logs, go directly to “Errors and error logs”
(page 65)).
