    Description

      Consider 3 nodes cluster. Non-primary node lost network connection and triggered failover. In this situation agent decided to shutdown the node b/c it assuming there is a network outage. Later when network outage has been resolved primary communicates with shutdown node first and initiated cluster rebuild adding the failed node back. At the same time CMAPI Failover Agent does the same and after cluster has been reformed following requests sent by the primary Agent triggered another sequence of restarts adding one node at time to reform a cluster.
