[Networker] write speed tests using bigasm?

I need to use bigasm to do NetWorker write speed tests on four LTO-3drives on a storage node server.

1. I assume that when I run the save command on the snode to test eachdrive that I'll need to havethe other 3 drives disabled so NetWorker will use only the specificdevice I want to test? Is this the only way to force it to

use a given drive for the save test?

2. If I want to test all the drives simultaneously to see how fastNetWorker can write to them concurrently then Iassume I would need to run 4 saves and set the max target sessions to 1for each device?

3. Kind of a last dumb question, I know, but it's been a while sinceI've used bigasm, butI assume I'll need to have a NetWorker labeled tape in the drive justlike with any save, correct?

I will be using hptapeperf tool also to test basic write speed outsideof NetWorker.

Is it worth turning compression on and off on the drives when doingthese tests or just leave it on?


Thanks.

George
