System event logging has stopped and a BMC malfunction is assumed
(System Health is Steady Green, Internal Health is Steady Green, External
Health is Steady Green, and Power is Steady Green).
Cannot read System Event Log
from the system console.

1.
Examine console messages for any EFI errors or warnings about BMC
operation or communications.
2.
Examine the BMC’s Heartbeat LED; if it is not Flashing Green, replace
the core I/O board FRU (see
).
3.
Test the operation of the BMC by toggling the UID locator switch LED
on the front panel -- the Blue LED is turned On/Off by the BMC, when
this switch is toggled.
Preceding problem is fixed when BMC’s Heartbeat LED is Flashing Green,
and the System Event Log resumes logging
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, internal
OS is non-responsive (hung).

health is steady green, external health is steady green, and power is steady
green).
Nothing may be logged for this condition.
1.
Reset the system using one of the following methods:
a.
Use the iLO 2 MP to reset the system:
•
From the command menu of text interface via SSH or Telnet,
use the
TC
command.
•
From the web GUI,
Reset through INIT or TOC signal
from the
Power & Reset
menu on the
Virtual Devices
tab.
For more information see the Integrity iLO 2 Operations Guide.
b.
Use a tool (such as a ACX-10 Torx screwdriver or appropriately size
allen wrench) to depress the INIT button on the front panel to start
system initialization.
2.
Reboot the OS.
3.
Obtain the system hardware status dump for root cause analysis.
4.
Examine the iLO 2 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices. See
“Errors and Reading Error Logs” (page 148)
for information.
The problem is fixed when the root cause has been determined, and the
OS is running normally.
Front panel LEDs indicate the server detected a fatal error that it cannot
recover from using OS recovery routines (for example, System Health is
MCA occurs during server
operation; the server reboots the
OS.
NOTE:
Server reboots OS, if
enabled.

Flashing Red, Internal Health is Steady Green, External Health is Steady
Green, and Power is Steady Green).
1.
Capture the MCA dump with the EFI command,
errdumpmca
. If the
system can boot the OS, you can capture binary MCA dump files online.
2.
Examine the iLO 2 MP logs for entries related to processors, processor
power modules (PPMs), shared memory, and core I/O devices (see
“Errors and Reading Error Logs” (page 148)
).
