AFAIK if you tell Legato to start a single saveset, e.q. 'all', ndmp will
dump this to one tape drive only.
However if you supply more savesets and parallelism is configured for the
tape drives (and the drives belong to the targeted pool) savesets are
'devided' over the available drives.

Dunno any other method of verifying the utilisation than by checking the
MB/s in the Networker admin.
(which, as I recently learned here, can be done by a script as well :)
