Use the following commands to remove and subsequently mount a NFS datastore. It should be noted that there’s both a NFS and NFS41 storage type – be mindful which one you’re using.

First check to see the current NFS datastores:

esxcli storage nfs list
esxcli storage nfs41 list

Then remove the datastore:

esxcli storage nfs remove -v NFS_Datastore_Name
esxcli storage nfs41 remove -v NFS_Datatore_Name

Now re-add the datastore that was removed:

esxcli storage nfs add -H NFS_IP|NFS_HOSTNAME -s Share_mount_point_on_the_NFS -v DatastoreName
esxcli storage nfs41 add -H NFS_IP|NFS_HOSTNAME -s Share_mount_point_on_the_NFS -v DatastoreName
