Diagnostic tools overview

The following tools are available to help you identify and solve hardware-related problems:

vTroubleshooting charts

These charts list problem symptoms and steps to correct the problems. See the Chapter 6, “Symptom-to-FRU index,” on page 59 for more information.

vDiagnostic programs and error messages

The built-in self-test (BIST) program checks the BladeCenter unit during startup and generates error messages if problems are found.

The system diagnostic program, Real Time Diagnostics Version 1.3, tests the major components of your BladeCenter unit. The Real Time Diagnostics software is available from the IBM Support Web site at http://www.ibm.com/systems/ support. It is run from the IBM Director Management Console window (under the BladeCenter task in the Task panel).

To obtain the Real Time Diagnostics program, go to the following Web site: http://www.ibm.com/systems/support.

1.Select Servers from the list at the left of the window.

2.Select Downloadable files from the list at the left of the window.

3.In the Downloadable files by category list, select Diagnostic.

4.Click the entry for Real Time Diagnostics and follow the instructions on that page.

vLight Path Diagnostics feature

Use the Light Path Diagnostics feature to identify system errors quickly. On the BladeCenter unit, the Light Path Diagnostics feature consists of the LEDs on the front and rear of the BladeCenter unit and on the front of the modules and blade servers.

Identifying problems using the Light Path Diagnostics feature

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 components also might be on. These LEDs help identify the cause of the problem.

This section provides the information to identify problems that might arise during installation using the Light Path Diagnostics feature.
