Problem
A failback operation will may not be able to complete if a host in the cluster is offline or faulty.
...
The following scenarios illustrate cases that result in the failure of the failback operation.
...
Faulty Node
In a multi-node cluster, if one node is faulty then failback will not start.
...
IO Filter Unavailable
In a multi-node cluster, all hosts are healthy but one node's IO filter is unavailable. Failback will not start.
Success Scenarios
...
Maintenance Mode
In a multi-node cluster, all hosts are healthy but one host is in maintenance mode. Failback will be able to continue.
...
Faulty Host Corrected
In a multi-node cluster, one host is faulty and that faulty host is replaced with a healthy host. Failback will be able to continue.
...
Faulty Host Removed
In a multi-node cluster, one host is faulty and that faulty host is removed from the cluster (removed from inventory). Failback will be able to continue.
