Start Oracle ClusterWare Resources on the Compute Nodes
With your grid disks rebuilt, it's time to get your Oracle cluster operational. Since your Oracle Cluster Registry will not
be available because you've dropped your ASM disk group that stored it, you will need to start CRS in exclusive mode
on one compute node and then manually start an ASM instance in order to recreate your DBFS_DG ASM disk group. We
recommend first disabling the automatic restart of Oracle CRS by issuing the following command:

[root@cm01dbm01 ~]# /u01/app/11.2.0.3/grid/bin/crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.
[root@cm01dbm01 ~]#

■ if you elect not to disable oracle CrS from automatically starting, you can use the crsctl stop res
ora.crsd -init command to stop CrS and prevent it from restarting.
