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
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
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
