Sundiag System Exerciser

Use the Sundiag System Exerciser to determine real-time use of system resources
and peripheral equipment such as Desktop Storage Modules and External Storage
Modules. The Sundiag System Exerciser verifies that the system is functioning
properly. For information about how to use the Sundiag System Exerciser, see the
Sundiag 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 or the SunDiagnostic
Executive.
Note – The Sundiag System Exerciser is not applicable to the SPARCclassic X
terminal.

Forth Toolkit

The Forth Toolkit is a basic diagnostic utility and system interface. If there is any
problem with your operating system, the Forth Toolkit automatically starts, as
indicated by the appearance of the ok prompt.
You can also choose to access the Forth Toolkit by halting the system. For
information on how to access the Forth Toolkit, see Appendix C "On-Board
Diagnostics."
