I?m 80% sure that the answer to this is "no", but I promised a client that 
I?d get a fresh answer anyway.

If one extends a LUN that is under an NSD, and then does the OS-level 
magic to make that known to everyone that could write to it, can the NSD 
be extended to use the additional space?

I can think of lots of reasons why this would be madness, and the 
implementation would have very little return, but maybe a large customer 
or grant demanded it at some point?

Liberty,
