Diagnostic Tools

The following diagnostic tools are available for the Sun Server X2-8.

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 about BIOS POST diagnostics, see BIOS POST .

Service Processor (Oracle ILOM)

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

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

SunVTS

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 .

Pc-Check

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 the Oracle ILOM. For more information about using Pc-Check, see Performing Pc-Check Diagnostic Tests.

U-Boot Diagnostics

U-Boot diagnostics run automatically when the server is started or booted. However, to see the output, you must connect a serial terminal to the SER MGT port on the SP. U-Boot tests basic hardware functions to ensure that there is enough functionality to boot the SP. For more information, see U-Boot Diagnostic Start-Up Tests.
