I know for multi-volume datasets UNIT=(TAPE,2) handled the mount of volume3 while volume1 rewound and unloaded. I do not remember if you could allocate 2 units and have concatenated input volumes alternate between them. AVR might have helped since it say "Find the device with the Tape Volume and allocate the DD to it" but I do not think it would handle the case where you want to reuse a drive where the tape has unloaded - It was for allocation at step start.
All true, but the thread is about distinct DD cards, beginning with SEP, and drifting into AFF. Joel Ewing complained that the default takes too many drives, but hasn't offered a practical means for IBM to allocate drives, when the user specifies neither SEP nor AFF, that would allow reducing the allocation to less than one drive per DD.
