Here's an interesting situation.  DLT media is upwards compatible.
So is DAT.  I'm sure it applies to other media as well.

I'll use DLT as an example.  You have a DLT 7000 drive and a DLT 4000
drive.  You have two media types: DLT70 and DLT40.

You can put a DLT40 tape into either drive.

A DLT70 tape can only go into the DLT 7000 drive.

How can you specify that media type DLT40 can go into either drive?

I'm guessing: create two Storage resources, with different Media
Types, but both refer to the same device.

David Boyes is trying to talk Kern into ;-) implementing configuration settings that allow for a list of media types and different lists for read/write operations. I guess that, in the end, it wuill be implemented, but it might happen sooner if someone started coding - this seems no to have a high priority for Kern...

I thought about this some time ago and the only real conclusion I came to was that it was easiest to only use higher capacity drives.

It does make upgrading more expensive though.

Indeed, but it creates a nice market for used tape drives :-)
