Hi Steve,
The new BIRT report in the OnCommand Console gives what you are looking for. One thing to note is that, it just the filer/vfiler under the column name Storage Server.
The old reporting infrastructure does not allow to report both filer and vfiler volume in one report.
Attached is the sample output for your reference.
Also pls take a look at this course on how to create and customize BIRT reports.
