Explanation
12X controller recovered; Do NOT replace any FRUs
Response
The 12X controller recovered from a failure. The location
code of the 12X controller is in the error log with the
procedure FRU as point of reference only.
Check if all I/O Adapters in the loop recovered. The
four leftmost digits of SRC word 7 represent the loop number
in hexadecimal format. Convert the loop number to decimal
format. Using the HMC, locate and record the decimal loop
number's information in the Hardware Topology screen.
Determine what I/O Adapters or 12X switches are connected to
that loop. Determine if any I/O Adapter in the loop are in
a failed state.
If there are I/O Adapters in a failed state, the
partition to which the failed I/O Adapter is connected may
need to be re-IPLed to complete recovery.
If there are no I/O Adapter(s) in a failed state but
there are errors logged against I/O Adapter(s) or I/O
Processor(s) for the same loop, close those errors. The
controller recovered successfully.
Problem determination
No action is required.
