Sun Microsystems 280R manual Firmware OS Software

The SunVTS system exerciser is a graphics-oriented UNIX application that enables the continuous exercising of system resources and internal and external peripheral equipment. For more information about SunVTS software, see “About Exercising the System Using SunVTS Software” on page 173.

UNIX-based Sun Management Center (formerly Sun Enterprise SyMON) software allows you to monitor the system hardware status and operating system performance of your server. For information about Sun Management Center software, see “How to Monitor the System Using Sun Management Center Software” on page 177.

Which method or tool you use to diagnose system problems depends on the nature of those problems. If your machine cannot load the operating environment software, use POST and OpenBoot Diagnostics to isolate failed components. If your machine starts up and loads the operating environment software, use SunVTS software and Sun Management Center software to monitor or exercise the system.

The following chart provides an overview of which tools to use to diagnose hardware problems locally.
