Mount resources in UNKNOWN state after upgrading/modifying the VCS cluster configuration
# hares -display mnt1 -sys blender
mnt1 State blender OFFLINE|STATE UNKNOWN
When upgrading Veritas Cluster Server (VCS) the file types.cf (/etc/VRTSvcs/conf/config/types.cf) used to define bundled resource types was not updated.
This lead to agent binaries/scripts being passed an unexpected number of arguments during resource probe and meant that the cluster high availability daemon (had) was unable to determine the state of cluster resources after start up.
To solve the issue had should be stopped and /etc/VRTSvcs/conf/config/types.cf replaced with the correct copy for the currently running version of VCS. This is normally placed at /etc/VRTSvcs/conf/types.cf during the VCS upgrade/installation.
