Yes. You will have to write an assembler (sorry) program to call the RACROUTE macro. I've been wanting to package up basic RACROUTE into a CSL routine, but haven't had the time.

Shared RACF database with MVS is only possible if the MVS system is not in a sysplex. GRS on the MVS system must be configured to perform RESERVE/RELEASE on the volume in response to an ENQ/DEQ. Some tape managers (e.g. IBM Tape Manager for z/VM) can talk to DFSMSrmm on z/OS if you want to use the z/OS tape catalog. I would guess that VM:Tape has an equivalent function. (JR?)
