About Diagnostic Tools

The system provides both firmware-based and software-based diagnostic tools to
help you identify and isolate hardware problems. These tools include:
Power-on self-test (POST) diagnostics
OpenBoot Diagnostics (OBDiag)
SunVTS™ software
Solstice SyMON software
Remote System Control (RSC) software
POST diagnostics verify the core functionality of the system, including the main
logic board, system memory, and any on-board I/O devices. You can run POST even
if the system is unable to boot. For more information about POST, see "About
Power-On Self-Test (POST) Diagnostics" on page 218 and "How to Use POST
Diagnostics" on page 219.
OBDiag tests focus on system I/O and peripheral devices. Like POST, you can run
OBDiag even if the system is unable to boot. For more information about OBDiag,
see "About OpenBoot Diagnostics (OBDiag)" on page 223 and "How to Use
OpenBoot Diagnostics (OBDiag)" on page 230.
The SunVTS system exerciser is a graphics-oriented UNIX application that permits
the continuous exercising of system resources and internal and external peripheral
equipment. For more information about SunVTS, see "About SunVTS Software" on
page 235.
Solstice SyMON allows you to monitor system hardware status and operating
system performance of your server. For information about SyMON, see "About
Solstice SyMON Software" on page 240.
Remote System Control (RSC) is a server management tool that provides remote
system administration for geographically distributed or physically inaccessible
systems. The RSC software works with the System Service Processor (SSP) on the
Enterprise 250 main logic board. For more information about RSC and SSP,
see "About Remote System Control (RSC)" on page 241.
