I'm just wondering if anyone has successfully got this working ?
My NAS host is a Bluearc (now HDS) attached to a Scaler i500 with 3 LTO6 drives and I'm running NetBackup 7.5
It seems that no matter how much I try, I can never get a policy to stream to multiple tape drives at once.
A Typical NDMP Policy:

Mill,
Have you set the "Maximum jobs per client" setting under Host Properties > Master Servers > Master Server > Global Attributes to more than "1"?
Another part that you'll need to include is the "NEW_STREAM" directive in your policy. Unless you have that between your two folders, it'll all be backed up in a "row" as one stream which won't be split into multiple jobs. (Which is why you also need to up the "Maximum Jobs per Client") Each stream will be ran with it's own job, with a parent job for both.

Does it only spawn one job or does a second one sit in a Queued state in the Activity Monitor, waiting for the first one to end?
Check Host Properties --> Master Server and bring up the Properties dialog.
In 'Global Attributes', make sure 'Maximum jobs per client' is something greater than 1.
Also check storage unit veritas-ny-hcart-robot-tld-0-bmf-01-ny to make sure number of drives and Max concurrent jobs are greater than 1 also.
You could try using the NEW_STREAM directive, although you should not have to:
NEW_STREAM

Yessir, I've set the Maxiumum Jobs Per Client.
Not entirely sure what you mean by the NEW_STREAM directive. What my backup client selection looks like now is
/__VOLUME__/fs2/ads/DIRECTORY1
NEW_STREAM
UNSET_ALL
UNSET
/__VOLUME__/fs2/ads/DIRECTORY2
Does that sound correct ?

Try it my way once:
NEW_STREAM
/__VOLUME__/fs2/ads/FOLDER1
NEW_STREAM
/__VOLUME__/fs2/ads/FOLDER2

Aha, this is looking promising.
I'm getting 3 jobs running now, one master and two underneath. The only issue now is that the 2nd set of folders is telling me that there are no drives available for the backup.

It works! I can't thank you enough. I've had multiple calls to my storage + backup vendors and come up empty.

Good to hear! The first job is the parent job, to look after the child jobs. It will stay running as long as any of the child jobs are runnng.
