A good idea. However, we only have 3390-3 volumes. And, as I said in
another post, if I have a large amount of "unused" space in a SMS pool,
then management becomes unglued. Of course, I could just leave the entire
space allocated to a zFS file. I'll see if I can talk my manager into
that. Thanks for the idea.
I don't know whether to be comforted or irritated to see people still
suffering from the stupidity of ancient volume architectures. I have a bag
full of cheap USB thumb drives that are bigger than a mod 3. Nobody has seen
a real 3390 in at least a decade. Storage volumes are all virtual now. Why
not just make 'em as big as you need and be done with all this nuttiness?
This is not stupidity of ancient volume architecture. The architecture
was quite OK in ancient times. The stupid thing is to conserve the
ancient architecture. I'm aware it's often choice of management, not
technical staff.
When we talk about mainframe A.D. 2009 we simply don't have such
problems! Think about EAV or NFS attached USB.
3390-3 is history, as Bus&Tag, punched cards or other Dodo's. Yes, you
can still use it - that's one of the mainframe strengths, but you don't
have to.
