[b]I need to figure out how to get the amount of capacity that has been "touched" (written data) by servers it has been provisioned to.[/b]
This data is available via command line query from Hitachi Device Manager, which seems to be how Capacity Reporter gets its data on HDS USPv arrays, but I am not sure if CR actually pulls this piece of data. If the aps_v_hds_virtual_volume table contains ALL HDS virtual volume information known to CR, it apparently doesn't know about "touched" capacity.
