Problem with Terminalserver using MOP download

Markus Waldorf_1 — Tue, 08 Mar 2005 13:24:13 GMT

Hello, maybe someone can help me here trying to figure out what's wrong. I had to replace a Decserver 700 with one that does not have a FlashRAM card, so it will need to download the OS from MOP. The Terminalserver has 08-00-2B-2E-48-AC. The system is runing OVMS 7.3-1, Decnet phase IV. I attached to the console port and the Decserver is trying to get WWENG1.

I receive the following error:

SYSTEM@RFEW02>
%%%%%%%%%%% OPCOM 8-MAR-2005 19:06:41.70 %%%%%%%%%%%

Can you connect to the terminal server
using MCR NCP CONNECT TS012
?

Nope. It's stuck trying to download the OS. I does also not respond to sending a "break" at the console (attached to port_1 of the server). I also disconnected the NIC, tyring to get a Local> prompt. But no luck. Unfortunately the server does not even have a slot for inserting a flashcard, like the other 700-08 modules that I have. There are 7 other Decserver 700 on the same switch, and connecting to them works fine.

Markus,

It seems that you have enabled both (DECnet IV MOP and LAN MOP). Never tested if they can coexist (and now I have no oportunity to do so), but reading the migration procedure from DECnet to LANCP (and back) it is described to disable DECnet MOP when using LANCP and viceversa. See:

http://h71000.www7.hp.com/doc/731FINAL/6017/6017pro_099.html#index_x_5264

So, try to disable mop services on one of them.

Hi, thanks for the reply!

SYS$EXAMPLES:LAN$POPULATE.COM does not find anything, and LANCP> sho dev /mop shows that I have EWA0 enabled. To my knowledge, CLUSTER_CONFIG_[LAN].COM was never done on that machine. But I did the following"

NCP>set circ ewa-0 state off
NCP>set circ ewa-0 service disabled
NCP>define circ ewa-0 service disabled
NCP>set circ ewa-0 state on

SYSTEM@RFEW02>rep/en

SYSTEM@RFEW02>mc ncp
NCP>connect node ts012
Target does not respond

now I have to wait... since I'm not in the office to switch the TS off/on.

When you connect a terminal to the console port of the server (port 1 by default), when server messages do you see on the terminal?

Markus

Are you check to connect with terminal server
using the next command?

NCP>connect node TS12 via EWA-0 physical address 08-00-2B-2E-48-AC

Saludos, Daniel.

as you have now disabled DECnet MOP download then you should define the node in LANCP
(DEFINE NODE)

Where do the logicals MOP$LOAD and MOP$NAMED_LOAD refer to ?

Are you using the same network connection as with the old decserver ? If not, are your network speed and duplex settings 10/half ?
Had about the same problem years ago but didn't keep details.

Thanks to everyone who responded! Meanwhile I found the problem. It was a bad network cable.
