Always

1. Check storageclass in running cluster, thin-csi is present:
$ oc get sc 
NAME             PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
thin (default)   kubernetes.io/vsphere-volume   Delete          Immediate              false                  41m
thin-csi         csi.vsphere.vmware.com         Delete          WaitForFirstConsumer   true                   38m

2. Delete thin-csi storageclass:
$ oc delete sc thin-csi
storageclass.storage.k8s.io "thin-csi" deleted

3. Check storageclass again, thin-csi is not present:
$ oc get sc
NAME             PROVISIONER                    RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
thin (default)   kubernetes.io/vsphere-volume   Delete          Immediate           false                  50m

4. Check vmware-vsphere-csi-driver-operator log:

5. Only first time creating in vmware-vsphere-csi-driver-operator log:
