Troubleshooting MCAs
Cause
In general, MCAs are partition-based crashes and are detected and reported by CAE. To obtain a general
overview about an MCA event, run show CAE –L, and then use the command show CAE –E –n <ID>
to obtain more details for the CAE event.
To view problem action statements about the MCA event, use the show cae —L —c 10 command and
note the Sl.No. Then display detailed information about the bad FRU including probable cause and
recommended action by using the show cae -E -n xxxx command, where xxxx is the Sl.No.
