and External Storage Modules. The SunDiag System Exerciser verifies that the system
is functioning properly.
The exerciser is shipped with SunOS and is preinstalled on a SPARCstation 10
system. If selected during the SunInstall (operating system loading) procedure, the
exerciser can be run at any time. The SunDiag System Exerciser is in the
directory
/usr/diag/sundiag
(for SunOS 4.1.3) or in the directory
/opt/SUNWdiag/bin
(for SunOS 5.1 and later versions). If the SunDiag System
Exerciser is not found on the system hard disk or server, you can load it from CD.
For information on how to use the SunDiag System Exerciser, see the SunDiag User’s
Guide. Appendix A, “Loopback Connectors,” in the SunDiag User’s Guide explains
how to connect the external loopback connectors required for some options.
If SunDiag passes, the system is operating properly. If SunDiag fails, the error
messages should indicate the part of the system which has failed. If the error
messages are not descriptive enough, you may need to run POST or the Sun
Diagnostic Executive.
SunDiagnostic Executive
The SunDiagnostic Executive is an independent operating system. It runs exhaustive
subsystem tests independent of SunOS. Run the SunDiagnostic Executive if all POST
tests pass, in order to determine which field-replaceable unit (FRU) needs to be
replaced. For information on POST, see “Power-On Self Test Detailed Description” on
page 14 earlier in this chapter. The SunDiagnostic Executive, which provides you
with thorough diagnostics, is described in the SunDiagnostic Executive User’s Guide
for the SPARCstations.
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, and is
indicated by the
ok
prompt. You can also choose to enter the Forth ToolKit by
halting the system.
To enter the Forth Toolkit:
1. Save all your work and quit all applications.
The following screen summarizes the steps you need to take to halt the system
and enter the Forth Toolkit.
