If you can write a small CMS program which uses this CCW, then you can ATTACH the drive to your CMS user, mount the tape, then run the program. For a 3490E drive, this is a CCW opcode of x'97'. You need to use command chaining to put a NOP command in the CCW string after this one. I don't have such a program. I also don't have access to a z/VM system.
