LANCP Errors

[T. Simpson]

Has anyone seen this LANCP error? This is a DS10 VMS 7.3-2 (update 4), 2-node cluster.

The other node (also a DS10) has problems as well. I get this near the end of the show command:

T.

VMS732_LAN-V0400 provides a new LANCP.EXE. One of the fixes involves displaying counters (but I can't confirm if it's the same problem you're seeing).

LAN-V0400 is incorporated into UPDATE-V0700

I'd recommend installing update 7 to see if it fixes the symptom. If you don't want to take the reboot right now, you might be able to pull the kit apart, extract the new LANCP and try running it (unsupported, and untested...)

[Dave Laurier]

I can confirm John's story. We have had the same issue here, same software versions, same hardware. After the installation of the patch kit the problem has gone.

[T. Simpson]

Thanks for your responses.

I will apply the patch today.

Tom
