The following diagnostic tools are available for the Sun Fire X4800 server.
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 about BIOS POST diagnostics, see BIOS POST .
You can use the Integrated Lights Out Manager (ILOM) to diagnose system problems by viewing the following:
Component information to determine component fault status.
The ILOM system event log.
For more information about using the ILOM to diagnose system issues, see Using the ILOM to Monitor the Host.
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.
For more information about using the Sun VTS to diagnose system issues, see Using SunVTS Diagnostics Software .
The Pc-Check diagnostics can test and detect problems on all motherboard components, drives, ports, and slots. This program can be accessed and executed from ILOM. For more information about using Pc-Check, see Performing Pc-Check Diagnostic Tests.
