[Veritas-vx] VxVM volume / plex size inconsistency?

[Joe Bloggs]

Tried a google search and a search of the veritas-vx archive for this, 
couldn't find it, although I'm guessing it's a widely known (and obvious) 
one....

Why does the volume size in a striped set (eg 104432, below) become less 
than the total size of the plex (eg  104448, below) ?

Thanks,

Joe.
