Sun Microsystems service manual Sun Blade T6320 Server Module Diagnostics Overview

2.1Sun Blade T6320 Server Module Diagnostics Overview

There are a variety of diagnostic tools, commands, and indicators you can use to monitor and troubleshoot a Sun Blade T6320 server module.

■LEDs – Provide a quick visual notification of the status of the server module and some of the FRUs.

■ILOM firmware – This system firmware runs on the service processor. In addition to providing the interface between the hardware and the Solaris OS, ILOM tracks and reports the health of key server module components. ILOM works closely with POST and Solaris Predictive Self-Healing technology to keep the system up and running even when there is a faulty component. For more information about ILOM, see these documents:

■Sun Integrated Lights out Manager 2.0 User’s Guide, 820-1188

■Sun Integrated Lights Out Manager 2.0 Supplement for Sun Blade T6320 Server Modules, 820-2546. This document describes ILOM information specific to the UltraSPARC and the Sun Blade T6320 server module. It also provides command comparisons of the ALOM CMT and ILOM CLI command sets.

■Appendix D of this service manual provides some information about using the

ALOM CMT CLI.

■Power-onself-test (POST) – POST performs diagnostics on system components upon system reset to ensure the integrity of those components. POST is configurable and works with ILOM to take faulty components offline if needed.

■Solaris OS Predictive Self-Healing (PSH) – This technology continuously monitors the health of the CPU and memory, and other components. PSH works with ILOM to take a faulty component offline if needed. The Predictive Self- Healing technology enables Sun systems to accurately predict component failures and mitigate many serious problems before they occur.

■Log files and console messages – Provide the standard Solaris OS log files and investigative commands that can be accessed and displayed on the device of your choice.

■SunVTS™ – An application that exercises the system, provides hardware validation, identifies possible faulty components, and provides recommendations for repair.

The LEDs, ILOM, Solaris OS PSH, and many of the log files and console messages are integrated. For example, when the Solaris software detects a fault, it will display the fault, log it, pass information to ILOM where the fault is logged, and depending on the fault, one or more LEDs may be illuminated.
