Run POST.
POST performs basic tests of the server components
and reports faulty FRUs.
• If POST indicates a faulty FRU, replace the FRU
(Action 9).
• If POST does not indicate a faulty FRU, go to
Action 8
“Running POST” on
page 31

Run SunVTS.
SunVTS provides tests used to exercise and
diagnose FRUs. To run SunVTS, the server must be
running the Solaris OS.
• If SunVTS reports a faulty device replace the
FRU (Action 9).
• If SunVTS does not report a faulty device, go to
Action 11.
“Exercising the System
With SunVTS” on page 48
9.
Replace faulty
FRU.
The fans, blower, power supplies, and hard drives
are hot-swappable.
The other FRUs require that you shut down the
server to perform a cold-swap.
After replacing the faulty FRU, go to Action 10.
“Replacing Hot-
Swappable and Hot-
Pluggable FRUs” on
page 55
“Replacing Cold
Swappable FRUs” on
page 65
10.
Verify the repair.
Various commands and utilities can be used to
verify the functionality of the system components.
Two useful commands are:
• The ALOM
showfaults
command
• The ASR
showcomponents
command
If the FRU is blacklisted, you can manually remove
it from the black list with the
enablecomponent
command.
If the fault is cleared, and the component is not
blacklisted, the repair is verified well enough to
boot the server. For added assurance, you can run
the SunVTS diagnostic software.
“To Run the
showfaults
Command” on page 26

with Automatic System
Recovery (ASR)
Commands” on page 44

Contact Sun for
Support.
The majority of hardware faults are detected by the
server’s diagnostics. In rare cases it is possible that
a problem requires additional troubleshooting. If
you are unable to determine the cause of the
problem, contact Sun for support.
