Yes.

Yes, this worked, if I remove the multipath devices and do a vgscan, I'm back to where I was before deactivating and can once again mount the volumes.

I've included a typescript of the session below this, perhaps you can find steps I'm missing.  But it sounds as though you're surprised by the behavior.
