Let’s see usage
% crsctl check cluster -all
prod01:
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

crsctl pin css is used to associate node name with node number. i.e if olsnodes shows prod01 as 1, then it should persist. This is helpful if you intend to run pre 11.2 database
crsctl pin css -n prod01
crsctl pin css -n prod02
To check daemon status, following commands need to be used
Check crsd – crsctl check crs
Check cssd – crsctl check crs
check evmd – crsctl check evm
crs_unregister is replaced by crsctl delete resource
