Ranga, You ought to be able to define tape drives in the IOCDS as "reconfigurable" between LPARs. That way, you can vary off a drive from the z/OS LPAR and reassign it using the HMC and vary it on to the Linux LPAR. And vice-versa. Very manual process, but it should work.
This is so much simpler if both z/OS and Linux are running as guests of z/VM. then CA:VMTape with STAM handles the whole thing for you. We're doing it now, sharing tapes among six LPARs.
