It doesn't: You know that, because the PRIMARY volume are divided by what node
they correspond to, and the OFFSITE volumes are divided by what day they were
written (and sent offsite).

So, to a good approximation, every offsite tape volume carries a tiny stripe
of data from every node.

I think not.  If P001 is dead for some reason, you'd have to RESTORE VOLUME
first.
