Oracle Message PROC-00015 - Failed to initialize the cluster registry successfully

ERRORFailed to initialize the cluster registry successfully
CAUSEThere are the following possible causes: The backend is not reachable. This could happen if the permissions are not set correctly for a shared device backend. CSS could not be contacted because of communication failure. This could happen if the cluster registry was never initialized at PROCR_INSTALL_LEVEL and one tried to initialize it at other OCR levels.
ACTIONMake sure that cluster registry was initialized properly. Make sure that the clusterware is working.
