Meaning of aie / aio / bvpssp in config file?

I'm upgrading a VAX to Ultrix 3.1 (from 1.2, no less) and discover
that the config file format has changed somewhat. Most of it seems
clear enough from the configuration file maintenance guide and the man(4)
pages, but not everything. Specifically, I find these two entries confusing:
For a tu81 tape drive, the entry seems to be something like this:
controller klesib0 at vaxbi0 node 0
controller uq0 at klesib0 vector uqintr
tape tms0 at uq0 drive 0
controller aie0 at vaxbi? node?
controller bvpssp0 at aie0 vector bvpsspintr
tape tms0 at bvpssp0 drive 0
For ra disk drives, the entry seems to be something like this:
controller kdb0 at vaxbi0 node?
controller uq0 at kdb0 vector uqintr
disk ra0 at uq0 drive 0
disk ra1 at uq0 drive 1
controller aio1 at vaxbi? node?
controller bvpssp0 at aio1 vector bvpsspintr
disk ra0 at bvpssp0 drive 0
(Yes, I know that the same uq number can't be used for both.)
What are the aie, aio and bvpssp things? I don't seen any explanation
of these in the documentation. Am I just looking in the wrong place?
Are those parts of the entries >even necessary<?
