Clear Faults Detected During POST
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
“Disabling Faulty Components” on page 50 .
In most cases, the replacement of the faulty FRU is detected when the service
processor is reset or power cycled. In this case, the fault is automatically cleared from
the system. This procedure describes how to identify a POST-detected fault and, if
necessary, manually clear the fault.
1. After replacing a faulty FRU, at the ILOM prompt use the
show faulty
command to identify POST-detected faults.
Faults detected by POST are distinguished from other kinds of faults by the text:
Forced fail
. No UUID number is reported. Refer to CODE EXAMPLE: Fault
Detected by POST on page 48 .
If no fault is reported, you do not need to do anything else. Do not perform the
subsequent steps.
2. Use the
component_state
property of the component to clear the fault and
remove the component from the ASR blacklist.
Use the FRU name that was reported in the fault in Step 1 :
The fault is cleared and should not show up when you run the
show faulty
command. Additionally, the Service Required LED is no longer on.
3. Reset the server.
You must reboot the server for the
component_state
property to take effect.
4. At the ILOM prompt, use the
show faulty
command to verify that no faults
are reported.
