Problem Summary: As of the VxVM 3.1.1 release, the man-page path has changed to /opt/VRTS/man. In previous releases the man-page path was /opt/VRTSvxvm/man. This new path is not documented in the Sun Cluster 3.0 12/01 Software Installation Guide.
Workaround: For VxVM 3.1.1 and later, add /opt/VRTS/man to the MANPATH on each node of the cluster.
