problems that might be caused by a faulty fan or power input. Environmental
faults can also be caused by room temperature or blocked air flow.
■ POST-detected faults – Faults on devices detected by the POST diagnostics.
■ PSH-detected faults – Faults detected by PSH.
1. At the Oracle ILOM prompt, type the show faulty command.
2. If a fault is displayed, check the output to determine the nature of the fault.
The following examples show the different kinds of output that might be
displayed:
