ActionSymptom/ConditionStep
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).
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.
2. Examine the iLO MP logs for entries related to processors, processor
power modules, shared memory, and core I/O devices (See “Errors
and error logs” (page 65) for more details).
The issue is fixed when the MCA does not repeat or the source of the
MCA has been eliminated.
MCA occurs during server blade
operation. The server blade
reboots the OS.
Note: The server blade reboots
OS if enabled.
8a
Front panel LEDs indicate that the server blade detected a fatal, front
side bus error.
System firmware is running to gather and log all error data for this
MCA event.
1. Examine the iLO MP logs for entries related to processors, processor
power modules, shared memory, and core I/O devices (see “Errors
and error logs” (page 65)for more details).
MCA occurs during server blade
operation; server blade reboot of
OS is prevented.
Note: The troubleshooting
actions for this step are identical
to those in Step 8a, except that
the server blade in this step must
be hard reset to begin the
booting process.
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, see “Front panel LEDs” (page 15) for more information on LED
locations and states.
Diagnostics
A suite of offline and online support tools are available to enable troubleshooting server blade
issues. In general, if the operating system (HP-UX) is already running, HP does not recommend
shutting down the server blade. Use the online support tools.
If the OS cannot be booted, use the offline support tools to resolve the issue. The offline support
tools are available from the UEFI partition. Once you resolve the issue preventing booting, boot
HP-UX, and use the online support tools for any further testing.
If it is not possible to reach the UEFI from either the main disk or from LAN, you must
troubleshoot using the visual fault indicators, console messages, and system error logs that are
available.
Offline Diagnostics Environment
The Offline Diagnostics Environment provides a support tools platform that enables you to
troubleshoot a system that is running without an operating system. With Offline Diagnostics,
you can test systems that cannot be tested using the online tools.
The HP Integrity Servers and Itanium Workstations Offline Diagnostics and Utilities CD-ROM is
shipped with all Integrity systems and Itanium® workstations. This CD is updated quarterly, at
which time new functions and features can be added, new hardware diagnostics can be
incorporated, and performance can be enhanced.
