Some quick notes on removing Oracle Nodeapps in a cluster.

Take a note of current config of node using:  srvctl config nodeapps -n nodename -a

To remove nodeapps:  srvctl remove nodeapps -n o2hp113

To re-create:  srvctl add nodeapps -n nodename -o $ORACLE_HOME -A xxx.xxx.xxx.xxx/255.255.255.0/laninterface .
