You have two choices on how to use two (or more) drives in a changer.

One way is to use the RAIT (RAID using tapes) driver to stripe (or
mirror) your data across the drives.  With striping you should be
able to increase your throughput writing to tape.

Another way is to have two configs, each using one drive and each
backing up a subset of your clients.  You will also need separate
holdingdisks and changer configs for each.

It would be nice if you could just have one config and have taper
be able to write images to multiple drives simultaneously, but as far
as I know it isn't possible.
