Difference on using SRVCTL and CRSCTL commands:
Use SRVCTL to manage Oracle-supplied resources such as
Listener,
Instances,
Disk groups,
Networks.
Use CRSCTL for managing Oracle Clusterware and its resources.
Oracle strongly discourages directly manipulating Oracle-supplied resources (resources whose names begin with ora) using CRSCTL. This could adversely impact the cluster configuration.
If resource name begins with ora then use SRVCTL
