Hi Lindy,
Don't know if this will help, but I recall using a product about 10, maybe 15
years ago on our VM systems called: VM Magic , from a company called SDI (
looks like SDISW now ). It allowed the user to emulate any DASD device on
any real DASD device. In our case we needed to run a

We used to have a product under VM called VTAPE, from STK (now SUN) I
believe, that emulated virtual tapes and units on VM disks.
We do z/OS here, not VM, that is done by another department, so I could be

You are right, I know this product, but this is not the one I mean.
I searched some and I think it is this VTAPE product:

The Hercules and Flex emulators can also emulate tape drives using a
couple of different formats, AWS, etc.
How difficult would it be to do something similar on z/VM? And what
ways might someone go about it?
