You can perform an unplanned failover operation for an entire recovery group to make the destination VMs active in an emergency situation. Only VMs that are eligible fail over. After a recovery group failover, replication operations are disabled for the VMs that failed over. You can perform a recovery group failback operation to return replication operations to all source sites in the recovery group.
