3.3.2 Running the
showfaults
Command
The ALOM CMT
showfaults
command displays the following kinds of faults:
■
Environmental faults – Temperature or voltage problems that might be caused by
faulty FRUs (power supplies, fans, or blower), or by room temperature or blocked
air flow to the server.
■
POST detected faults – Faults on devices detected by the power-on self-test
diagnostics.
■
PSH detected faults – Faults detected by the Solaris Predictive Self-healing (PSH)
technology
Use the
showfaults
command for the following reasons:
■
To see if any faults have been passed to, or detected by ALOM CMT.

) for PSH detected faults.
■
To verify that the replacement of a FRU has cleared the fault and not generated
any additional faults.
