How to expand a distributed volume

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):

1. Back-End LUN expansion, which is what you discussed above
2. Concatenation of extents from a different storage volume
