When we have done PAGEADD and PAGEDELs for Volume migrations to new
UCBs, what it does is balance by I/O. While the PAGEDELS are going,
as soon as one write is completed, the next write starts, pretty much
round robin. In your case I would hypethosis it tries the first page
dataset on a volume an

I don't know how it works post-PAV.
But, before that you could only have one active PAGE D/S per pack.

Not true:
Pre-PAV, you could(should) have only 1 page dataset per volume.
With PAV, ASM ensured aliases to have access paths to all page datasets

That's what I said.
You'd get a messag
I don't remember a message like the one you mention.
