I've been digging through the compatibility matrices at e.g.

http://www-01.ibm.com/support/docview.wss?rs=663&context=SSGSG7&uid=swg21053218&loc=en_US&cs=utf-8&lang=en

which I'll parenthetically note were reasonably straightforward to find,
and reasonably simple to parse.  Nice.

But I didn't see a specific mention of virtual volumes.  I ass-u-me that
it's similar to the library manager situation:  i.e. a 6.2 server target
can interact with  sources down to 5.5;  but I don't seem to see
specific confirmation of that.

Anyone have feedback on that?
