With a successful RAC Cluster, running the Cluster Verification Utility
The "cluvfy stage -post crsinst" command as the Grid Infrastructure user checks the status of all components after the installation and configuration of the Cluster. Note : This does not and cannot check any database (RAC or non-RAC) that is created.
The "ocrcheck" commands by root are to check the integrity of the Cluster Registry and Local Registry. (You would run "ocrcheck -local" on each node of the Cluster).
