NFS 4.1 datastores might become inaccessible after failover or failback operations of storage arrays

NFS 4.1 datastores might become inaccessible after failover or failback operations of storage arrays.

When storage array failover or failback operations take place, NFS 4.1 datastores fall into an All-Paths-Down (APD) state. However, after the operations are complete, the datastores might remain in APD state and become inaccessible.


As per the VMware this issue is happening in hosts older than build version 16075168 and it is resolved in the newer version. We tested it in our environment and the newer version works fine without any datastore failure.
