Type the ILOM
show
/SP/faultmgmt
command to check
for faults.
The faultmgmt command displays the following
types of faults:
• Environmental faults
• Solaris Predictive Self-Healing (PSH) detected
faults
• POST detected faults
Faulty FRUs are identified in fault messages using
the FRU name. For a list of FRU names, see
TABLE 1-3.
Section 2.5.3, “Displaying
System Faults” on
page 2-21

Check the Solaris
log files for fault
information.
The Solaris message buffer and log files record
system events and provide information about faults.
• If system messages indicate a faulty device,
replace the FRU.

Run the SunVTS
software.
SunVTS can exercise and diagnose FRUs. To run
SunVTS, the server module must be running the
Solaris OS.
• If SunVTS reports a faulty device replace the FRU.
• If SunVTS does not report a faulty device, go to
Action

Run POST. POST performs basic tests of the server module
components and reports faulty FRUs.
• If POST indicates a faulty FRU, replace the FRU.
• If POST does not indicate a faulty FRU, go to
Action

Section 2.6, “Running
POST” on page 2-31

Determine if the
fault is an
environmental
fault.
If the fault listed by the show /SP/faultmgmt
command displays a temperature or voltage fault,
then the fault is an environmental fault.
Environmental faults can be caused by faulty FRUs
(chassis power supply, fan, or blower) or by
environmental conditions such as high ambient
temperature, or blocked airflow.
