We have Data ONTap 8.1.2P4 loaded on a NetApp 2240 clustered filer. We have Multistore running as well. When you you go to edit the vFiler settings, the Network tab is missing. In the vFiler units screen it shows the assigned networks for that vFiler but it does not when you go to edit the vFiler. I have upgraded System Manager to version 3.x to make sure it was not a bug that was fixed. We had been running version 2.02 prior to the upgrade.
