How to expand a distributed volume
What is the proper way to expand a distributed volume in a metro configuration?
I know that you can not do mobility between two distributed volumes, or between a
distributed volume and a non-distributed volume.
Any thoughts on how to do this?

Will, a collegue of mine was able to migrate the extents of the two legs but the expandable space of the virtual volume did not change. So it seems the best way is to expand the backend lun. I have brought this up to the product management group

Ankur,
I guess I was looking at a way to do this without going through the meta expansion on the VMAX. That's been one of the nice things with the VPLEX and non-distributed volumes, we can do a local mobility rather than the trouble of a meta expansion. I should have stated this in my question.
So, my real question is, other than "physical" device expansion at the VMAX, is there a good way to expand a distributed volume?
Thanks for getting back to me.

Will have you checked out the admin guide? theres a whole section on expanding a volume. Assuming you are doing 1:1 encapsulation you can expand the array volume then have vplex expand the virtual volume

Will the only way ive seen this done is via backend expansion. Im going to have to try to see if one can migrate the extents of the two legs to larger volumes then expand the virtual volume

Ankur, thanks for taking the time to look at this. I opened a RFE as well.

I know this is late, but there are 2 methods, both outlined in the Admin guide (Chapter 6 in the 5.4 guide):
