Cannot read System Event
Log from the iLO console.
System event logging has stopped and a iLO MP malfunction is
assumed (system health is steady green, and power is steady
green).
1. Examine console messages for any UEFI errors or warnings
about iLO operation or communications.
2. Test the operation of the iLO MP by toggling the UID locator
switch LED on the front panel -- the blue LED is turned on/off
by the iLO, when this switch is toggled.
3. Reset iLO 3 MP, by using the iLO 3 physical presence
pinhole button on the rear panel of the server.
The preceding issue is fixed when the SEL resumes logging.

OS is non-responsive
(hung).
Front panel LEDs indicate that the server power is turned on,
and it is either booting or running the OS (system health is
steady green, and power is steady green). Nothing might be
logged for this condition.
1. Use the iLO 3 MP Command Menu to initiate a ToC, using
the
tc
command.
2. Reboot the OS and escalate.
3. Obtain the system hardware status dump for root cause
analysis.
4. Examine the iLO 3 MP logs for entries related to processors,
processor power modules (PPMs), shared memory, and core
I/O devices (see
for details).
The preceding issue is fixed when the root cause has been
determined.
