I've actually read through
http://docs.hp.com/en/14982/guidetosuccesswithSCSI-FCRouter.pdf.  I isolated
the router paths from each other, zoning each router to the VA7410 but not
to each other.  And I set up LUN Security on the VA7410 so that each router
only saw the LUNs it was supposed to.

It seemed to work with 4 SCSI routers, but when I powered on a 5th router,
one of the first 4 would disable its LUN map.
