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.
Example:
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 .
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.
4. At the ALOM CMT CLI prompt, use the
showfaults
command to verify that
no faults are reported.
