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<?

As long as you only have one "drive 0" tape, you can replace "uq0" with "mscp". > controller aie0 at vaxbi? node? > controller bvpssp0 at aie0 vector bvpsspintr > tape tms0 at bvpssp0 drive 0 The AIE is a VAXBI module with the capability of supporting both Ethernet and a TK50. Generally you see it supporting only one. The "aie" is the base module. I don't remember what the "bvp" part stands but there are two. bvpssp - BVP Storage Systems Port - (tape controller) bvpni - BVP Network Interconnect - (Ethernet) The real module names for the AIE varients are: DEBNT DEBNK DEBNA DEBNI As far as I know the the xxxNK was the only one to support the TK50. > > 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 This is the normal entry for a KDB50. As long as you only have one "drive 0" disk in the system you can replace the "uq0" with "mscp". > disk ra1 at uq0 drive 1 > controller aio1 at vaxbi? node? > controller bvpssp0 at aio1 vector bvpsspintr > disk ra0 at bvpssp0 drive 0 > The AIO is a VAXBI controller for the RD54.

I don't seen any explanation > of these in the documentation. Am I just looking in the wrong place? I don't remember what AIE, AIO and BVP stand for. As mentioned earlier SSP is Storage Systems Port. You might find something if go searching through to some of the system include files. I'd suggest the /usr/include/vaxsysap and /usr/include/sys/errlog.h as places to start. They might have buried in them somewhere the true names of those acronyms. > > Are those parts of the entries >even necessary<? If you don't have those devices, then you don't need entries for them in the configuration file. I'm guessing that you have a VAX 82xx or 83xx. > > Paul DuBois > dubois@primate.wisc.edu -- Alan Rollow alan@nabeth.enet.dec.com

If you do something like "man ra", the manual pages break down the entries as appropriate to each architecture. I'd assume the hardcopy for section 4 of the manual is the same, though there's not much to tell you to look there. 2) About 98% of what worked in the 1.2 config file still works, though a few options have been added and one of two things deleted. The only thing I remember getting blown out on was that the "args on xxxx" part of the "config" statement dissapeared. 3) I haven't the faintest idea what most of them wierd things are. Some are imaginary and merely keep things structured the way that config and the auto-config code is set up, some reflect adapters appropriate to the various busses, non-busses and attempts at imcompatibilty... -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@uunet.uu.net Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
