Just a word of warning so you don't have any bad surprises later - the DataCore
driver was no longer being maintained so it was deprecated in the Rocky release
and removed in Stein.

If I remember correctly, they actually stopped running third party CI to test
their driver in Queens, but we didn't catch it in time to mark it deprecated in
that release. It could very well be fine for Queens, I just don't have any data
showing that for sure.

Make sure you have it installed in your venv. Try this with:

/openstack/venvs/cinder-17.1.2/lib/python2.7/bin/pip freeze | grep websocket
