You really should have an onsite and offsite pool for each server. You
need an onsite tape pool to do restores, and you need the offsite pool
to be able to rebuild dead volumes from your onsite pool.

You might consider going back to a locally-created offsite pool for each
server, and get rid of the server-to-server setup. If you don't have
don't have enough library space to leave the onsite and offsite pools in
the library, you'll have to remove the offsite pool volumes from the
library. If you have to do that, you might as well go back to a
traditional pool setup.
