OK. So, for a more general question, how do people configure and use multiple drives in a tape
library? How does Amanda plan for them and make use of them? How do you tell Amanda that it should
use one tape in one drive and another tape in the other drive as opposed to finishing one tape and
then continuing on to a second tape (the runtapes parameter)?
Any pages in the wiki that discuss the configuration and behavior of multiple tape drives in a
library? And parameters that affect the behavior?

I've just acquired and set up a new Overland T48 with two LTO7 tape drives.
I already have an Overland T24 with one LTO6 tape drive that I've been using
for a few years.
I plan on transitioning our large data to the LTO7 and thought I might keep
the basic administrative backups on the LTO6, using the same instance of
Amanda.
Anyone know how to configure this? I can imagine defining two changers and
specifying which to use in the dumptype, but I don't see quite how that
would be done.
You'll need two different configurations. The planner tries to fill a
certain amount of tapes (of a determined size) so it can't handle mixed
storage like you suggest.
If they were of the same size you could play with the aggregate changer
but that's not the case.
I'd suggest one configuration for the admin data on LTO6 and one
configuration for the other data on LTO7 (externally scheduled as
appropriate)
