The current NetApp ONTAP (8.2 c-mode) operating system has an NFS related issue with the showmount -e command. This issue prevents Oracle VM from seeing any NFS file systems on a NetApp storage appliance running this operating system.
NetApp has provided a workaround for ONTAP 8.2 on the NetApp support site. Further instructions are provided for resolving this issue on My Oracle Support with Doc ID 1640848.1 available at the following URL:
https://support.oracle.com/epmos/faces/DocumentDisplay?id=1640848.1
You must reapply the workaround after you have upgraded an Oracle VM Server.
