Two weeks ago, I posted a question about 
VM giving incorrect information about disks.

Since no one here responded (except Kris, but not
with an explanation or solution), I figured I should 
close the story by posting what I got from IBM.

They don't know HOW it happened, but they said
that somehow a bit in the RDEV got klobbered, 
resulting in VM being sure of one thing, when DSF
(which actually asks the CU for the facts) knew 
otherwise.

The solution was fairly simple:
VARY OFF nnn
SET RDEV nnn CLEAR
VARY ON nnn

The CLEAR did exactly that, cleared up 
the confusion. :-) Then I was able to 
ATTACH TO SYSTEM again, and 
all is well.
