Should a failure occur, the front panel LEDs and the SEL helps you identify the problem or FRU:
•
The front panel LEDs and LAN LEDs of the server blade change color and blink to help identify
specific problems, and display LAN activity.
•
The SEL provides detailed information about the errors identified by the LEDs.
For server alerts of levels 3-5, the attention condition on the server LED can be cleared by accessing
the logs using the
sl
command, available in the iLO 2 MP command mode. To access the iLO 2
MP from the console serial port, enter
Ctrl-B
or
ESC-(
.
If the LEDs and SEL do not give you enough information for you to identify the problem you are
experiencing, HP also provides diagnostic tools with each operating system (see
“Troubleshooting
Tools” (page 91)
).
NOTE:
Always check the iLO 2 MP SEL in the case of a blinking yellow or red front panel health
LED, before replacing any hardware.
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, etc., pertaining to a server blade error
or fault.
2.
View the front panel LEDs (power and health), locally; or remotely through the iLO 2 MP
vfp
command.
3.
Compare the state of the server blade’s LEDs (off; flashing or steady; red, green, or amber)
with the LED states listed in
Table 12 (page 88)
.
4.
Go to the step number of
Table 13 (page 88)
, as specified in the right column of
Table 12
(page 88)
, located in the row which corresponds to your front panel LED display state.
5.
Read the symptom/condition information in the left column of
Table 13 (page 88)
.
6.
Perform the action(s) specified in the Action column.
7.
If more details are required or desired, 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 (the event log and/or the forward progress
log).
You can follow the recommended troubleshooting methodology, and use
Table 13
and
Table 14
(page 90)
, or go directly to the subsection of this chapter which corresponds to your own entry
point of choice.
Table 11
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 98)
).
