Cause

FIBRE_CHANNEL Datastores changes were made after commissioning the hosts into SDDC Manager.

Changing the name of the Datastore after commissioning the hosts can also cause this issue.

Resolution

From the SDDC Manager UI, Decommission the impacted ESXi hosts and then Commission back into SDDC Manager.

Then create the WLD Cluster.

If Datastore name was changed, change it back to what it was at time of commissioning the host to SDDC
