Difference between crsctl start crs and crsctl start cluster
We can say that not has the same result.
crsctl start/stop crs - Manage start/stop the entire Oracle Clusterware stack on a node, including the OHASD process, this command is to be used only on the local node..
crsctl start/stop cluster - Manage start/stop the Oracle Clusterware stack on local node if you do not specify either -all or -n and nodes remote if option -n or -all be specified , NOT including the OHASD process. You can't start/stop clusterware stack without OHASD process running.
Despite crsctl start/stop crs manage entire Oracle Clusterware stack on local node crsctl start/stop crs not allow you to manage remote nodes, unlike crsctl start/stop cluster that allows you to manage all the nodes, but if the process OASH is runing.
To manage Oracle Clusterware Stack on remote nodes, the ohasd (Oracle High Availability Services Daemon) must be running on all managed nodes. (i.e using crsctl start cluster -n
Then if you try use crsctl start cluster -n node1,node2 and your local node is node1 and on node1 or node2 OHASD not running this command will fails.
