Issues with Setting Up a Cluster
Common issues that can arise when setting up a cluster are:
Connectivity—Make sure that all candidate cluster nodes can communicate with each other.
Hostnames—Make sure that the cluster node hostname is mapped to its actual IP address.
Version Compatibility—All cluster nodes must be running the same version and patch level of TDV and Active Cluster.
See TDV Installation and Upgrade Guide for details about the requirements for Active Cluster.
