VCS WARNING V-16-1-12123 Type RVG defined more than once
VCS WARNING V-16-1-12095 Aborting hacf: errors encountered
The issue is caused by the fact that the RVG resource type exists more than once.
In versions prior to 5.1, there existed a separate types file for VVR related resources.
The file "VVRTypes.cf" is no longer needed as VVR agents are now included in standard "types.cf" file.
To resolve the issue, remove the "include VVRTypes.cf" line entry from main.cf
VCS should now start successfully with "hastart".
