Environment

VCF 9.0

Cause

This issue can be encountered if the follow scenario has occurred - 

• The NFS Datastore has already been mounted to the all the ESX hosts using the portgroup name specified in the bringup json file, prior to the bringup workflow being initiated.
• The bringup workflow is initiated.
• The NFS Datastore Configuration task failure error outlined above is encountered.
• The NFS Datastore is attempted to be unmounted, but cannot be as the VCF Installer bringup workflow requires it to be mounted.
• The portgroup name is then changed and the NFS Datastore Configuration task succeeds once, and fails again
• Subsequently, ESX Host Configuration task failure error outlined above is encountered.

Resolution

Perform a redeployment with reimaged hosts.

Do not mount the NFS Datastore to all the ESX hosts prior to the bringup workflow being initiated.
