Hi Brian,
Could you try the following query on your system and see if it helps.
SELECT array.name AS array, volume.name AS root_volume_name, aggregate.name AS aggregate_of_root_volume
FROM
storage.array array,
storage.volume volume,
storage.aggregate AGGREGATE,
storage.vfiler vfiler
WHERE vfiler.array_id = array.id
AND vfiler.name = 'vfiler0' -- Indicates that this is the hosting storage system
AND vfiler.root_volume_id = volume.id
AND aggregate.id = volume.aggregate_id
The result in my system looks something like:

Thanks,
Shailaja
