Clear POST-Detected Faults
Use this procedure if you suspect that a fault was not automatically cleared. This
procedure describes how to identify a POST-detected fault and, if necessary,
manually clear the fault.
In most cases, when POST detects a faulty component, POST logs the fault and
automatically takes the failed component out of operation by placing the component
in the ASR blacklist. See
“Managing Components (ASR)” on page 45 .
Usually, when a faulty component is replaced, the replacement is detected when the
SP is reset or power cycled. The fault is automatically cleared.
1. Replace the faulty FRU.
2. At the Oracle ILOM prompt, type the
show faulty
command to identify POST
detected faults.
POST-detected faults are distinguished from other kinds of faults by the text:
Forced fail
. No UUID number is reported. For example:
-> show faulty
