PROBLEM:

While shutting down crs, got below error.

[root@bin]# ./crsctl stop crs
CRS-4013: This command is not supported in a single-node configuration.
CRS-4000: Command Stop failed, or completed with errors.

SOLUTION:

In case of standalone grid, there will not be any crs . Only has component will be there.
So use the below command to shutdown the service.s

[root@bin]# ./crsctl stop has
