Clearing POST Detected Faults
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
“1.8 Managing Components With Automatic System Recovery Commands” on page 46 ).
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 POST detected faults and, if necessary, manually clear the fault.
1.
After replacing a faulty FRU, at the ALOM CMT CLI prompt use the
showfaults
command to identify POST detected faults.
POST detected faults are distinguished from other kinds of faults by the text:
Forced fail
, and
no UUID number is reported.
See
Example 1-5 .
If no fault is reported, you do not need to do anything else. Do not perform the subsequent
steps.
2.
Use the
enablecomponent
command 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 . See Example 1-6 .
The fault is cleared and should not show up when you run the
showfaults
command.
Additionally, the Service Required LED is no longer on.
3. Power cycle the server.
You must reboot the server for the
enablecomponent
command to take effect.
