Diagnostic Tools

The following diagnostic tools are available for the Sun Fire X4640 server.

BIOS/POST

From the point that the host subsystem is powered on and begins executing code, BIOS code is executed. The sequence that BIOS goes through, from the first point where code is executed to the point that the operating system booting begins, is referred to as POST (power-on self-test).

POST works in conjunction with other processes to complete initialization and booting. POST focuses on thoroughly testing devices as well as providing meaningful information to users when errors occur. For more information on BIOS/POST, refer to Sun Fire X4640 Server Service Manual

Service Processor ILOM

You can use the Integrated Lights Out Manager (ILOM) to diagnose system problems by viewing the following:

• View component information to determine component status.

• View the ILOM system event log.

For more information on using the ILOM to diagnose system issues, see Using the ILOM to Monitor the Host.

SunVTS Diagnostics

SunVTS is the Sun Validation Test Suite, which provides a comprehensive diagnostic tool that tests and validates Sun hardware by verifying the connectivity and functionality of most hardware controllers and devices on Sun platforms. SunVTS software can be tailored with modifiable test instances and processor affinity features.
