When to Use Diagnostics
You should use each type of diagnostic tool in the appropriate circumstances. Table
2–2 summarizes the available diagnostic tools and lists when to use each diagnostic
tool.
TABLE 2–2
Summary of Available Diagnostic Tools
Diagnostic Tool
When or why to use
Power-On Self
Test
Executes at power-on when
Stop(L1)-d
keys are pressed and held or
the
diag-switch?
parameter is set true. The POST code resides in the
boot PROM and is driven by the Pok (Power ok) signal from the power
supply. POST tells you if the main logic board (MLB), the DSIMM in slot
0, or the MBus module in slot 0 fails. Described later in this chapter.
On-Board
Diagnostics
Tests such as the Ethernet test and the diskette drive controller test are
available. You must be at the
ok
prompt to run on-board diagnostics. The
on-board diagnostics reside in the boot PROM. Described later in this
chapter.
SunDiag System
Exerciser
Runs under SunOS. It displays real-time use of the system resources and
peripherals. The SunDiag System Exerciser tells you if your system is
functioning correctly or not. If SunDiag fails, run the Power-On Self-Test.
If all power-on self-tests pass, then run the SunDiagnostic Executive to
identify the problem. See the SunDiag User’s Guide for more information.
SunDiagnostic
Executive
Runs extensive, configurable subsystem tests independent of SunOS. Run
the SunDiagnostic Executive if all tests pass when you run POST.
Running the SunDiagnostic Executive allows you to troubleshoot which
field replaceable unit needs to be replaced. See the latest version of
SunDiagnostic Executive User’s Guide for the SPARCstations for more
information.
Forth Toolkit
Allows input to the system at the boot PROM level. Supports functions
such as changing NVRAM parameters, resetting the system, running
diagnostic tests, displaying system information, and redirecting input and
output. See the Open Boot 2.0 Command Reference for more information.
