That's right... One nsrstage process uses one drive exclusively.

If you cant stream off one adv_file device fast enough to keep a tape
drive at max speed then there's something amiss with your adv_file
device's io performance.

Subject: [Networker] Query in Staging from adv_file

I have few adv_file device and I have created a staging policy and add
all the adv_file to the same pool because, all the adv_file devices has
the same destination pool. But when I am giving "stage all save sets"
from the staging policy properties. NetWorker is staging from one
adv_file to one physical drive. I have enabled parallelism on physical
drive level set to 4. But networker is not doing multiplexing for staged
data. The physical drive is under utilized. If I do parallelism, I think
I can make the drive to perform at its maximum. 

Is it Networker's behavior of not to multiplex data staged from disk to
tape. So will networker will use one dedicated drive per stage session
from a adv_file.

Plz advice.
