Hi
I probably failed to make my self clear.
1. Yes MOP is part of a whole heap of programs that go to
make up DECNET
2. MOP stands for Maintenance Operations Protocol and that
what is was for.
3 It pre dates DECnet (Well at lest internally in DEC)
4. It can be run on its own.
5. It's a much lower level system than LAT or LAVC that run
at the application (top) level of the OSI Model
6. It runs at the network level (Layer 3) in the seven
layer OSI model
7. Of course there is a physical network and enough of a
driver in the firmware in the target VAX to exchange
frames with the MOP running in the boot server. (I found a list of them)
So in that sense it is running a subset of
Decnet. However let's not confuse a low level maintenance tool with all
the good stuff the full version of Decnet gives
you.
8. Its twenty-five years since I was a product manager in
DEC SWS. No wonder I'm a bit hazy on this stuff!

Your server (the VAX 4000-200) does have to be running DECnet. Er no it
doesn't and isn't. I attended a 1976 DEC

was discussed. It just my personal memory has a long
access time.
Download and run was around long before Decnet was thought of.
I'm not sure why I'm responding to this troll, but I can't resist.
The server must be running a MOP listener. That's the protocol that the
client uses when you boot the ethernet device. MOP is a DECnet protocol.
For many versions of VMS, the way you get a MOP listener is to install
DECnet. For VMS 7.0 and later, there's a separate MOP listener that
provides just that part of DECnet.
There's no Decnet or any other normal network
involved.
Crap. You MUST have a network to run a Local Area VAXcluster. You know,
a *Local Area Network*?
LAVC booting uses DECnet to boot. You can't make any of this work
without a LAN, without DECnet.
I suppose you'll keep flailing around hoping that something will work,
blaming others for your mistakes. Enjoy yourself.
I am also
beginning to suspect that the whole cluster thing is another GRH (Giant
Red Herring)
Huh? Nope, if you followed the very detailed directions you've been
given, you could diskless boot the server. You could then try to get a
disk set up and booted. Not a red herring at all.
Whats actually happening is an old diagnostic tool is
being used to
download and run a program on a remote system to exclude the disk
drives from the test.
LANCP is not an "old diagnostic tool" it's actually fairly recent.
Using CLUSTER_CONFIG as you're supposed to will use it to set up the
client download. Did you try that? Probably not.
