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 (a power supply or fan tray), 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.
■ To obtain the fault message ID (SUNW-MSG-ID) for PSH detected faults.
■ To verify that the replacement of a FRU has cleared the fault and not generated
any additional faults.
● At the sc> prompt, type the showfaults command.
The following showfaults command examples show the different kinds of output
from the showfaults command:
■ Example of the showfaults command when no faults are present:
■ Example of the showfaults command displaying an environmental fault:
