This message triggers when you attempt to mount a backup copy of an NFS datastore on a Storage Virtual Machine (SVM, formerly known as Vserver) with the root volume in a load-sharing mirror relationship.
The mount operation fails with the following message:
You may have reached the maximum number of NFS volumes configured in the vCenter. Check the vSphere Client for any error messages.
To prevent this problem, when you add a storage system running clustered Data ONTAP to Virtual Storage Console, you must use the cluster management IP address instead of the SVM IP address.
