Balancing 2 drives

I have 2 drives setup on my library. When I run a group job the 2 drives are mounted but only one tape at a time is written. Is there any way to get the job to write to both tapes or do I need to break the group up and run 2 separate jobs? Jimbo

On job (save stream) can only go to one device ... but of course you can start multiple streams.

However, most likely this will be done automatically, as long as you have setup the parallelism values correctly. Verify especially the ones for
- the server
- the client

By default, all values are set to 4 which is far to low for the server and one potential problem for your server behavior.

Set your server paralelism to 8 or higher.
With 2 Clients in a group, each with 4 savestreams, you will see both drives will be used.
If your clients dont provide enough savestreams you can lower
the device paralelism (target sessions) to 2.
Be aware if you are using both devices for backup autocloning might yield deadlocks. In addition there is no drive left for restores during backup sessions.
