Does Datacom support DS8860 DASD?
Datacom is not hardware dependent.
We are not aware of any problems with any DASD Hardware as any kind of
restriction with Datacom.
If you asking about EAV device support, then the answer is that r14
supports those devices and does take advantage of the cylinders above the
64k boundary.
R12 will support the devices as a normal 3390 device but will not take
advantage of the cylinders above the 64k boundary. Datacom uses EXCP as the
type of I/O in r12/r14, but I believe z/OS 1.13 has to be the minimal
release to allow that to happen (IBM restriction not Datacom r14).
