While TSM V6 does not run on z/OS on zSeries, it certainly still does on
Linux IFLs on zSeries. Let's not give IBM any more incentive to kill TSM
on big iron!

I think you are not considering what a 'tape library manager' does in
the TSM world.  The behavior you discuss is not likely to be useful in
the case the Original Poster was describing.

The key advantage to IRMM is that it presents varying resources in a
seamless manner.  In the dual-data-center configuration the OP
described, I think it would not be useful or desirable to access the
'local' and 'remote' drives interchangably.  In his place, I'd want
that separation clear and clean


Furthermore, I don't anticipate it would be worth learning Z-series
hardware and software in order to get access to multiple tape
libraries from one system.  TSM can do that already.

And TSM V6 doesn't run on Z-series.
