Unable to process configuration data model

[Jim Calciano]

I've added some new modules using "netopeer-manager add". I've previously successfully added the turing-machine model to my server, so I was following the same procedure. When I check "netopeer-manager list", the modules I added are listed. However, when I try to start my server using "netopeer-server -v 1", it fails. Google hasn't been any help regarding the line about "Unable to process configuration data model...", so I'm completely at a loss as to where to start debugging this issue

Here's that piece of my log:

netopeer-server[25643]: Adding base model "/home/jcalciano/bbf-fast/yin/bbf-fast-xtu.yin"
netopeer-server[25643]: Unable to process configuration data model /home/jcalciano/bbf-fast/yin/bbf-fast-xtu.yin.

I appreciate any help.

Thank you.

Hi Jim,

it seems that the YIN model you're using is missing some mandatory nodes, that is the problem. Try executing pyang on the model, it should tell you exactly what is wrong with it.

Thanks. That showed me what I needed to do to fix it.
