The version the original poster is asking about isn't old enough to use the 370 I/O instructions. MVS/SP 3.2 was the formal name for an early release of MVS/ESA. I don't know if he'll be successful in running that under z/VM in a machine defined with MACHINE ESA, but that's probably the only way he'll be able to do it on his z/890.
