Where's the Namespace window?

I'm trying to take a volume offline (so I can delete it). I get this message: "Volume xxx is mounted and has an active junction path. Therefore, the volume cannot be taken offline. Unmount the volume from the Namespace window to take the volume offline." I've searched high and low but cannot find the "Namespace windwow". The version is "NetApp Release 9.1P2: Tue Feb 28 18:17:30 UTC 2017"

Re: Where's the Namespace window?

When you are in SVM view (selected the particular SVM owning the volume), then there is the Namespace tab next to Overview and Volumes, before Shares.
