Hi,
as Demetrius said, its the migpr-Parameter that you can set with your
migration. The mountlimit is a parameter in the devclasses-table. You can
after setting mountlimit to "drives" just initiate migration by saying "upd
stg <yourstoragepool> hi=0 lo=0 migpr=4" and if there are date from more
than 4 clients that should store their data on different tapes
(collocation=yes) in that pool, 4 processes should start.

Best regards
Chris
