Thanks.

I tried this and it does not seem to give me what I need. I think the key item is that I am sharing tape drives outside of the sysplex, with non-participating systems. (Forced because these are not z/OS systems I am sharing with.)

Still googling for a workable solution.

Autoswitch. In z/OS the commands a v xxx,as,on or v xxx,as,off

I believe there is an IODF option to make the drives switchable.

Subject: tape drive RESERVE/RELEASE

Is there some option in RMM or the IODEF to have z/OS issue RESERVE/RELEASE 
commands to the tape drives?

We share some tape drives between z/OS, z/VM and z/VSE. z/VM and z/VSE 
automatically reserve/release the drives as needed, but z/OS (with RMM) does 
not. I have to issue a VARY OFFLINE/ONLINE to release/reserve the drives.
