This worked just fine.  I had done something similar on a small box (a
C10?) on ADSM 2.1.  We weren't sure if it would be any different dealing
with LUNs in a SAN with a 200 Gb DB than it was with unplugging adapters on
the portable disc cabinet with a DB of 100Mb.  After draining the storage
pools, an all night affair, it took about a half hour; switch LUNs, make
appropriate Network name change, add new paths to Library Manager, and back
in business.

I agree, this should work fine.  I think the thing that previous posters were
commenting on (saying that the db would become corrupted), that wasn't made
clear in the original question, is that you want to make sure you shut
down the
primary TSM server prior to breaking the mirror.   As long as you do that, I
don't see why it shouldhn't work....
