Error observed during transition of configuration

[gavaselv]

Hi,

I could observe error while pushing config via NSO. Seems like some environment variable issue or Device config is missing.

I have added new device(ASR-9k exr) in exising nso-4.7 setup. Downloaded Yang and installed drned properly as per the wiki.

failure PyTest not installed or DrNED running directory (/root/nso-4.7/nc/xmnr/ASR9K-gavas/test/drned-skeleton) not set up

Please help me in clearing this issue.

Can you provide the show packages package oper-status output?

Only thing I can think of relating to skeleton not being setup is the following:

ncs-make-package --service-skeleton python <package-name>

But I'm not entirely sure if it's related.

Or you are missing a python package called PyTest? Could you check the correlating ncs-java-vm/nso/devel.log files to see if it expands on the error?

Most likely the problem is caused by what the error message says - you need to have pytest installed (can be installed by running pip install pytest in the system shell); and you need to set up the XMNR directories - run drned-xmnr setup setup-xmnr in the device mode. The latter prepares also the drned skeleton mentioned in the message, this has nothing to do with a package skeletons.

Let me know if it does not help.
