You can use LEDs and software to identify faulty components, however, it is best to rely on software to determine if a component is faulty.
The fmadm faulty command displays the list of faults detected by PSH. You can run this command from the host or through the Oracle ILOM fault management shell.
This example shows how to check for faults through the Oracle ILOM fault management shell. You can also check for faults by typing show faulty at the Oracle ILOM prompt.

In this example, a fault is displayed that includes these details:
Date and time of the fault (2016-05-03/16:01:02).
UUID (2782ad0c-91cb-c780-9663-807f0bf806df), which is unique to each fault.
Message ID (SPSUN4V-8001-0J), which can be used to obtain additional fault information from Knowledge Base articles.
