That's probably more of a performance suggestion.  The system won't fall
over if you have connectivity to more than that, just don't try to
stream them all.

If you use the wizard for setup, it will use the serial numbers on the
drive, and will know that the drives attached to the other machine are
in particular positions in the robot.  No problem moving the tapes
there.

The master server doesn't need /dev/sg paths for the drives it's not
using.  It just needs to tell the robot to put a tape in that slot.
