It depends on two things:

First, which version of VMS?  If recent enough, there
is something called dynamic volume expansion (IIRC...
I use it, just don't know its official name).

Second, the shadow set (volume) needs to have been
initialized to allow the expansion, typically with the
/LIMIT qualifier (thus the dependence on a recent
enough version of VMS).
