Difference between crsctl start/stop crs and crsctl start/stop cluster

crsctl start/stop crs - This command starts/stops the OHASD process along with the complete Clusterware stack on the local node we are logged in.

crsctl start/stop cluster - This command starts/stops the Clusterware stack on a server except the OHASD process.

The following processes will still be running if we stop the cluster using crsctl stop cluster.

Note: The advantage of crsctl stop cluster compared to stop crs command is that it prevent the relocation of 'certain' resources to other servers in the cluster before the Clusterware is stopped on that server.
