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.
show cae -L -c 10
