Table 10 Advanced Low End Troubleshooting
Action
Symptom/Condition
Step
SEL logging has stopped (health is steady green and power is steady
green).
Cannot read SEL from the system
console.
6
1. Examine console messages for any UEFI errors or warnings about
operation or communications.
This issue is fixed when the SEL resumes logging.
Front panel LEDs indicate that the server blade power is turned on, and
it is either booting or running the OS (for example, health is steady
green and power is steady green).
OS is non-responsive (hung)
7
Nothing can be logged for this condition.
1. Use the iLO 3 MP Command Menu to initial 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, shared memory, and core I/O devices (see
“Errors and
error logs” (page 101)
for more details).
This issue is fixed when the root cause is determined.
Front panel LEDs indicate that the server blade detected a fatal error
that it cannot recover from through OS recovery routines (for example,
health is flashing red and power is steady green).
MCA occurs during server blade
operation. The server blade
reboots the OS.
8a
1. Capture the MCA dump with the UEFI command,
errdump mca
. If
the server blade can boot the OS, you can capture binary MCA dump
files online.
Note:
The server blade reboots
OS if enabled.
2. Examine the iLO 3 MP logs for entries related to processors, processor
power modules, shared memory, and core I/O devices (See
“Errors
and error logs” (page 101)
for more details).
The issue is fixed when the MCA does not repeat or the source of the
MCA has been eliminated.
Front panel LEDs indicate that the server blade detected a fatal, front
side bus error.
MCA occurs during server blade
operation; server blade reboot of
OS is prevented.
8b
System firmware is running to gather and log all error data for this MCA
event.
Note:
The troubleshooting actions
for this step are identical to those 1. Examine the iLO 3 MP logs for entries related to processors, processor
power modules, shared memory, and core I/O devices (see
“Errors and
error logs” (page 101)
for more details).
in Step 8a, except that the server
blade in this step must be hard
reset to begin the booting
process.
This issue is fixed when the MCA does not repeat.
You must hard reset the server
blade to clear the fatal condition
and boot the OS.
Troubleshooting tools
The HP Integrity BL860c i2 Server Blade uses LEDs and other tools to help troubleshoot problems
that occur in the server blade.
