Check connection (rsh or nimsh) between NIM server and LPAR.

NIM server needs to be connected with LPARs, either using rsh or nimsh protocol. In case this communcation is lost, mksysb backups or other tasks from NIM to this lpar will fail. So, I have made this simple script to check this connectivity between NIM and LPAR.

# You need to add parameter $1 as the name of the lpar (machine resource) to the script:
#
# Check machine resource exist on NIM:
lsnim -c machines|grep "$1" 1>/dev/null
if [[ $? -eq 0 ]] ; then
   echo
     else
    echo "ERROR: $1 machine resource does not exists on NIM." && exit 1
fi
#
nim -o lslpp $1 |grep bos.rte.odm 1>/dev/null

if [[ $? == 0 ]];then
    echo "Communication NIM-LPAR $1 is OK!!"
else
    echo; echo "ERROR: There's no connection between NIM and LPAR $1. Check configuration."
fi
echo

Just thanks if the post was helpful 🙂
