Chapter 3 System Administration 69
Automated remote event notification of system problemsis configurable through
RSCsoftware. For more information about RSC software, see “Using the Sun Remote
System Control (RSC) Card” on page74.
Control over the system’s ASR firmware functionality is provided by the OpenBoot
PROM commands. These are described in the current version of the document
OpenBoot Command Reference Manual.
Improved System Diagnostics Software
For enhanced serviceability and availability,the system provides different tools for
diagnostic testing and monitoring, namely:
■Power-on self-test (POST)
■OpenBoot Diagnostics
■SunVTS diagnostics
■Sun Management Center diagnostics
■Remote System Control (RSC) software
POST and OpenBoot Diagnostics are firmware-resident diagnosticsthat can run even
if the server is unable to boot the operating system. Application-level diagnostics,
such as SunVTS and Sun Management Center,offer additional troubleshooting
capabilities once the operating environment is running. The RSC software offers
monitoring and remote notification while the operating environment softwareis
running, and in addition providesaccess to the okfirmware prompt if the operating
environment is not running.
POST diagnostics provide a quick but thorough check of the most basic hardware
functions of the system. For more information about POST,see “How to Isolate
Failures Using Power-On Self-Test(POST)” on page 179, “About Isolating Failed
Components” on page 165, and “Isolating Failed Components” on page72.
OpenBoot Diagnostics provide a more comprehensive test of the system, including
external interfaces. OpenBoot Diagnostics is described in “About Using Diagnostic
Toolsto Monitor, Diagnose, and Exercise the System” on page 162, in “How to
Isolate Failures Using OpenBoot Diagnostics” on page181, and in “Isolating Failed
Components” on page 72.
At the operating environment level, you have access to SunVTS diagnostics. Like
OpenBoot Diagnostics, SunVTS provides a comprehensive test of the system,
including its external interfaces. SunVTS also allows you to runtests remotely over a
network connection, for example using RSC. Youcan only use SunVTS software if
the operating system is running. For more information about SunVTS, see “About
Exercising the System Using SunVTS Software” on page173, and “How to Check
Whether SunVTS Software Is Installed” on page198.
