2311 was a demountable disk that was SOMEWHAT similar in appearance to a 3340 drive; the last shop I was in that used them referred to them as "Maytags" 'cuz they loaded from the top. Also IIRC, IEBCOPY treated them just like any other DASD device.
The 2311, 2314, and both models of 3330 had top loading disks. I wouldn't call either version of the 3340 similar, as it was in a sealed enclosure, with a handle, we (ir)reverently referred to as a chamber pot.
IEBCOPY suffers from a design decision made at the beginning of its life - it has a built-in table of device characteristics and other constants, as I found out when I investigated why the MVS 3.8j version was getting errors processing 3390 PDSs. So the specific DASD supported depends highly on the version of IEBCOPY; there is the additional problem that IBM chose to re-use one of the type values (20.04 is used for the 9345 as well as one of the older units), so no one copy will support all extant devices.
