We have OnTap 8.3.2P3.
The NFS v4.0 is disabled.
cluster::> nfs show -v4.0 enabled
There are no entries matching your query.
but the -v4.0-write-delegation, v4.0-read-delegation and v4.0-acl are enabled.
cluster::> nfs show -vserver vserver -instance
General NFS Access: true
NFS v3: enabled
NFS v4.0: disabled
NFSv4.0 ACL Support: enabled
NFSv4.0 Read Delegation Support: enabled
NFSv4.0 Write Delegation Support: enabled
So as long as NFS v4.0 is disabled, the other v4.0 options are also disabled eventhrough they were enabled?
