Equally, it could be argued that the FBA DASD used to emulate ECDKD is in most cases not really 'spinning' DASD at all; but Christopher Blaicher was unassailably right when he said that emulated ECKD devices are what z/OS "DASD" controllers.see.
If one finds it amusing to do so, the reductionist game of describing "underlying reality" can be played over and over again, down to the quantum-electrodynamic level; but what must be programmed for, in a z/OS environment, is a notional.
