So two or more libraries?

A stgpool needs a device class. The devc would (i assume) be LTO, and the device
class needs a library name i.e.

def devc devc1 library=lib1  ....etc

The library definition i assume is VTL

def lib lib1 libtype=vtl serial=autodetect/<serial no> ...etc

So if there was a second library, you would need a second device class to point
to it. But you can't provide a second devc on the stgpool definition. So i think
you are correct in saying you don't think it is possible
