Chapter 6. Solving problems
Use these instructions to resolve any problems you may encounter while installing the blade server.
If you install the blade server in the BladeCenter unit and the blade server does not start, perform the
following actions:
• Make sure that the BladeCenter unit is correctly connected to a power source.
• Reseat the blade server in the BladeCenter unit (see “Installing the blade server in a BladeCenter unit”
• If the power-on LED is flashing slowly, turn on the blade server (see “Turning on the blade server” on
page 13).
• If you have just added a new optional device or component, make sure that it is correctly installed and
compatible with the blade server and its components. If the device or component is not compatible,
remove it from the blade server, reinstall the blade server in the BladeCenter unit, and then restart the
blade server.
If the blade server does not start after you have performed the preceding actions, see the
Problem
Determination and Service Guide
for your blade server on the IBM
Documentation
CD.
Diagnostic tools overview
Use this overview to locate specific diagnostic tools to diagnose and solve hardware-related problems.
The following tools are available to help you diagnose and solve hardware-related problems:
•
POST codes, error messages, and error logs
The POST error codes indicate the detection of a problem. See the
Problem Determination and Service
Guide
for more information.
•
Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See the
Problem Determination
and Service Guide
for your blade server.
•
Light path diagnostics
Use light path diagnostics LEDs on the system board to diagnose system errors. If the system-error LED
on the system LED panel on the front or rear of the BladeCenter unit is lit, one or more error LEDs on the
BladeCenter unit components also might be lit. These LEDs help identify the cause of the problem. Blade
server error LEDs are described in the
Problem Determination and Service Guide
for your blade server.
•
Dynamic System Analysis (DSA) Installable and Portable Edition diagnostic program
DSA tests the major components of the BladeCenter unit, including the management modules, I/O
modules, removable-media drives, and the blade servers, while the operating system is running. DSA
can be plugged into an existing IBM Director environment or installed without IBM Director present. For
documentation and download information for DSA, see http://www.ibm.com/systems/management/. For
more information about diagnostic programs and error messages, see the
Problem Determination and
Service Guide
for your blade server.
Note:
If you are unable to find the system-error logs in the blade server firmware code, view the
system-event log in the BladeCenter management module.
