You VM:Backup System Programmer is correct ... the "higher" density media will always be preferenced in the volser list sent to VM:Tape.
The simplest thing I can think to do is use a VM:Tape COMMAND EXIT that swaps the 2 volsers in the list. Alternatively, I suppose you could "outcode" (CHECKOUT) the 3590 tapes, I think that would prevent them from being selected (but you'd need to remember to check them back in before they can be scratched for reuse).

My question isn't how to make it work. It seems to be doing fine. The only problem and the reason for my question is that I have the virtual tapes defined as 3490C tapes. My quandary is the fact that I have the virtual tapes defined as the VMBackup Primary Resource Pool and and a 3494 robot with 3590 drives, located in a different location, as the VMBackup Copy Resource Pool. It works just fine for backups. Restores, however, result in VMBackup picking a 3590 tape rather than one of the 3490 tapes. I know, or think I know, that I can get around that using VMBackup Job Template files and specifying the input tape volser and/or density. That's a little awkward. I want the restores to be able to be done from the VMBackup screens so our admin. people can do them. The VMBackup System Prog. Ref says that the tapes for a restore are chosen from a density preference list with the higher density tapes, naturally, being chosen first. That's logical, but not what I want. Does anyone have any idea as to how to force VMBackup to use a different list? I have a question open the CA but I was hoping that someone has faced the same question .
