This is probably not what you want. Two device entries here are not
useful.

Also, for the autochanger as a whole, you will need at least two
concurrent jobs if you want to use both drives simultaneously.

Use this name as the device for the autochanger in the DIR configuration.

If you fix the autochanger device as mentioned above, yes. But what
you might want to try is
a) adding storage devices for LTO-1 and LTO-2 to the DIR
configuration, and
b) use those as the storage in the pool definitions.

No, but you define the single drives as storae devices in the DIR.
And you should allow job concurrency.
