Forth Monitor; System Exercisers - Sun Microsystems SPARCstation 5 Model 110 Service Manual

FORTH Monitor

The FORTH Monitor is a basic diagnostic utility and system interface. If there is any
problem with your operating system, the FORTH Monitor automatically starts, as
indicated by the appearance of the ok prompt (the Monitor also starts if auto-
boot? is set to false).
You can also choose to access the FORTH Monitor by halting the system. For
information on how to access the FORTH Monitor, see Appendix D. For extensive
information about tests you can run from the FORTH Monitor, see OpenBoot
Command Reference.

System Exercisers

Use the SunDiag System Exerciser (Solaris 2.4 and earlier) or SunVTS (Solaris 2.5
and later) to determine real-time use of system resources and peripheral equipment
such as Desktop Storage Modules and External Storage Modules. The System
Exerciser verifies that the system is functioning properly. For information about how
to use the System Exerciser, see the SunDiag User's Guide; for information about
SunVTS see the SunVTS User's Guide.
If SunDiag passes, the system is operating properly. If SunDiag fails, the error
messages should indicate the part of the system that has failed. If the error messages
are not descriptive enough, you may need to run POST.
