DS200 can't find load image

[Kirsten Knüttel]

I think, that the installation of TSM has something activated at NCL that didn't run before.
Normally we use LANCP (not DECNet) for the MOP-requests. So I think I must find, what TSM has activated at NCL.
Or am I wrong?

Uff, in good time to watch football I've implemented a workaroung. Another machine in the same cluster has now mop enabled and everything is working well.
Only one little problem with lancp:

show dev/mop

Device Listing, volatile database:
--- MOP Downline Load Service Characteristics ---
Device State Access Mode Clients Data Size
------ ----- ----------- ------- ---------
EWA0 Enabled NoExclusive NoKnownClientsOnly 246 bytes
LANCP> show dev ewa0/mop

Device Listing, volatile database:
--- MOP Downline Load Service Characteristics ---
Device State Access Mode Clients Data Size
------ ----- ----------- ------- ---------
EWA0 Enabled NoExclusive NoKnownClientsOnly 246 bytes
%LANCP-E-DEVNFND, Device not found in LAN device database, device EWA0

Even though I must find out why the other 2 machines don't work well (tomorrow).

I forgot something.

a difference between the two machines:

Here the one who works well:
NCL>show mop

Node 0 MOP
at 2006-07-04-20:37:20.854+00:00Iinf

command failed due to:
no such object instance

And here the one where the image can't be found:

mc ncl show mop

Node 0 MOP
at 2006-07-04-20:37:30.806+00:00Iinf

So it seems as if I only must disable mop at NCL. Perhaps somebody can give me the right commands for this?

ncl disable mop
ncl delete mop

and in NET$LOGICALS.COM there is a logical to enable/disable MOP.

[Wim Van den Wyngaert · Accepted solution]

The lancp process is serving the mop requests (just tested it here).

I think TSM disabled MOP download on the node.

mc lancp show mop
will show you if this is the case.
mc lancp set/change dev ewa0/dll=enable will reactivate it.

Note that when decnet and lancp are both enabled, they will fight to get the request. First come, first served.

The logical to disable mop during decnet startup :
def/sys/exec net$startup_mop "false".

Hi,

Ian, thank you for the commands

Wim:
I've tested it now, it is like you said. first, we've used LANCP, with TSM MOP at NCL was automatically enabled. When now a new MOP request arrived, LANCP and NCL fighted (like you said), but there was no winner and the software could not be loaded. I've now disabled the MOP at LANCP so that only the MOP at NCL was enabled and now the load requests were successfull.

So many thanks to all for your ideas, hints and tipps to find a solution for this problem.

I remember that the MOP protocols are not quite the same.

A decserver was connected with full duplex instead of half and lancp mop succeeded but ncl mop failed.
