Table 26 Advanced low end troubleshooting (continued)
Step Symptom/Condition
8a MCA occurs during server
operation; the server reboots the
OS. (NOTE: Server reboots OS,
if enabled)
8b MCA occurs during server
operation; server reboot of OS
is prevented. NOTE: The
troubleshooting actions for this
step are identical to those in
Step 8a, except that the server
in this step must be hard reset
to begin the booting process
You must hard reset the server
to clear the fatal condition and
boot the OS

Troubleshooting tools

Use the following tools to aid in troubleshooting the server.

LEDs

Front panel

The front panel of the system contains the power button/system power LED, health LED, System
Event Log LED, and locator switch/LED. The server use flashing states (for example, flashing amber
or red) on these LEDs to indicate a warning or an error.
There are a total of three buttons, arranged horizontally, with the UID button and the power button
each having an integrated LED. In addition to the two integrated button/LEDs, there is a health
LEDs

Health LED

The front panel health LED indicates the status of the components that are externally serviceable.
Whenever the external health LED is lit, the corresponding CRU should be lit for the failed
component.
Action
Front panel LEDs indicate that the server detected a fatal error that it
cannot recover from through OS recovery routines (system health is
flashing red, internal health is steady green, external health is steady
green, and power is steady green).
1. Capture the MCA dump with the UEFI command, errdump mca. If
the system can boot the OS, you can capture binary MCA dump files
online.
2. Examine the iLO 3 MP logs for entries related to CPUs, CPU power
modules (PPMs), shared memory, and core I/O devices (See
reading error logs" (page 80)
3. See "Troubleshooting tools" (page 75)
MCA Analysis Tool, in order to use MCAs to determine the most likely
faulty or failed CRU.
The preceding problem is fixed when the MCA does not repeat, or the
source of the MCA has been determined and dealt with.
Front panel LEDs indicate that the server detected a fatal, front side bus
error, caused by DIMMs; or by any parity in the I/O path between SBA,
LBA, or HBA (system health is off, internal health is flashing amber,
external health is steady green, power is steady green). System firmware
is running to gather and log all error data for this MCA event.
