[numewre]

Hi I have tried installing theses drivers with Ussri release:
made three changes
import http.cookiejar as cookielib
import urllib.request as urllib2
from cinder.volume import volume_utils as vol_utils
but now i am getting the below error:

This repo is for our legacy product VNXe3200, and it's verified for Ocata and older release.
It's not guaranteed that can be run under Ussuri.

Are you using it to manage VNXe3200 storage? You can use unity driver (https://github.com/openstack/cinder/tree/master/cinder/volume/drivers/dell_emc/unity) if you are managing Unity storage.

Hi Murray,

I am using VNXe3200 only.
Should I try to use unity driver? or these are only compatible with unity.

and also, i have removed the exception in /openstack/venvs/cinder-21.0.1/lib/python3.6/site-packages/cinder/volume/manager.py and now I can initialize driver but when creating LUN

You could try with Unity driver. cannot guarantee it works 100% for VNXe.

The error you paste is caused by different types of string in python2 and python3.
