Workload hosts failure

In this scenario, the workload hosts become unavailable, but the storage array is still online. The workload ICMP heartbeat links are lost, but the original synchronous and asynchronous RDF links are still available.

At this point, the original synchronous and asynchronous replication links and the original workload array are still available.
