Yeah. Swapping cards out fixed it anyway. MOYA is now semi functional.
Certainly MOP should deal just fine, unless someone implemented it very badly. Ditto any other DEC protocol. After all, DEC invented the spanning tree algorithm, so handling its implications was just elementary network algorithm design for all of us.

Well, I have recent experience of the problem. That's why I mentioned it.
We did do a LAN reconfiguration at the office. We added a dozen Cisco catalyst switches to get rid of the cable spaghetti we had between racks.
After the reconfiguration I was going to boot some of our Alphas and VAXen - which were now connected to the Catalyst switches - from the Infoserver. Earlier there was no problems at all, but now the boot didn't work at all. As there were no other changes made, I suspected the Catalysts. When monitoring what happened during the boot I found out that when the Ethernet adapter resets the link, the Catalyst starts the spanning tree listening period and blocks all traffic to and from the port until the listening period has ended. Unfortunately that seems to be too long a time for the protocol and the boot never continues.
This was verified on other Catalysts as well.
The solution is to disable spanning tree on the port where a booting node is connected. Then the booting problem is gone.
I think it is an overkill from Cisco to implement spanning tree on every possible switch port. I can understand the point, though, because there are too many LAN users nowadays which don't have a clue of what is happening in the LAN.

Kari

Hey Johnny,
Update the extended data for MOYA please. She is a MicroVAX II (KA630)
with 13M RAM in a BA123.
Thanks!

The moment it joins the cluster, it immediately loses connectivity.
There's between 5 and 10 milliseconds of latency between the two...but
that shouldn't matter...should it?
As I don't have a SCSI Qbus adapter, and I didn't get the TK50+TQK50 with
it, I can only MOP boot it. 60M disk is also not a lot.

CHIMPY Retro Tetris Update:
Mark Wickens is in the lead with a score of 7,640, followed by Vilaca with 1,574 (score not verified with screenshot so might not count).
Guys, we're still running until 23:59:00 GMT on 31-DEC-2013 so there's plenty of time to win random Arabic money AND certificates of Tetris awesomeness.
Telnet to CHIMPY.SAMPSA.COM or SET HOST CHIMPY, log in as TETRIS.
REMEMBER TO SCREENSHOT YOUR RESULT IF YOU GET A NEW HIGHSCORE. Or at least write down what date/time/node you came from if SET HOST, so I can verify the score..
