  Two things about your RA81s.  The first might be your problem.
The UDA-50 must be in the last slot (electrically) in your unibus backplane.
If it si not this could be causing your problems and potentially many others
as well.

  Secondly, you really MUST install vms 3.5 or higher.  There is a rather
nasty bug in 3.4 involving optimization for RA devices which could result
in the returning of stale data or even someone else's data.  Check your
vms system reports for more info.
