Joining and Leaving an Active Cluster
Any TDV Server (Version 7.0.6 or later) with a valid digital certificate can join an Active Cluster. All TDV metadata on the server joining the cluster is overwritten with the TDV metadata from the cluster. Also all TDV servers in an Active Cluster must be at the same version and patch level for both TDV and Active Cluster.
If a member of the cluster leaves the cluster, the remaining members of the cluster are made aware of the member leaving and continue to operate without any need for intervention. If the member rejoins the cluster, its metadata can be merged with the cluster or replaced with the cluster metadata. Manager displays the status of the cluster so that you always know the status of all members of the cluster. A TDV Server can be added or removed at any time.
