Yes, you are correct. The ScaleIO MDM credentials will need to be used.  Did you have to change your volume_driver path?
Hi,  I have integrated ScaleIO setup with OpenStack. The ScaleIO Cinder Driver didn't initialized on the OpenStack Controllers after adding the scaleio configurations in cinder.conf and restarting the volume service. Following are the logs from cinder/volume.log.  2017-09-22 12:13:48.803 527018 ERROR cinder.volume.drivers.emc.scaleio [req-232ce3cc-2575-4c77-b72a-0d76687147b1 - - - - -] Error getting domain id from name default: Unauthorized. 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service [req-232ce3cc-2575-4c77-b72a-0d76687147b1 - - - - -] Error starting thread. 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service Traceback (most recent call last): 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/oslo_service/service.py", line 708, in run_service 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     service.start() 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/cinder/service.py", line 234, in start 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     self.manager.init_host(added_to_cluster=self.added_to_cluster) 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/cinder/volume/manager.py", line 425, in init_host 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     self.driver.init_capabilities() 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/cinder/volume/driver.py", line 704, in init_capabilities 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     stats = self.get_volume_stats(True) 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/cinder/volume/drivers/emc/scaleio.py", line 999, in get_volume_stats 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     self._update_volume_stats() 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service   File "/usr/lib/python2.7/site-packages/cinder/volume/drivers/emc/scaleio.py", line 885, in _update_volume_stats 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service     raise exception.VolumeBackendAPIException(data=msg) 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service VolumeBackendAPIException: Bad or unexpected response from the storage volume backend API: Error getting domain id from name default: Unauthorized. 2017-09-22 12:13:48.808 527018 ERROR oslo_service.service 2017-09-22 12:13:48.834 245919 INFO oslo_service.service [req-de6fa29f-6e9e-4d23-8b40-8c56049b1ab8 - - - - -] Child 527018 exited with status 1 2017-09-22 12:13:48.847 527107 INFO cinder.service [-] Starting cinder-volume node (version 9.1.1) 2017-09-22 12:13:48.877 527107 INFO cinder.coordination [-] Coordination backend started successfully. 2017-09-22 12:13:48.878 527107 INFO cinder.volume.manager [req-5c0a7619-898b-44b8-bc47-3879195b2de3 - - - - -] Starting volume driver ScaleIODriver (2.0) 2017-09-22 12:13:48.879 527107 WARNING cinder.volume.drivers.emc.scaleio [req-5c0a7619-898b-44b8-bc47-3879195b2de3 - - - - -] Verify certificate is not set, using default of False. 2017-09-22 12:13:48.880 527107 INFO cinder.volume.drivers.emc.scaleio [req-5c0a7619-898b-44b8-bc47-3879195b2de3 - - - - -] ScaleIO get domain id by name request: [URL] 2017-09-22 12:13:48.881 527107 INFO cinder.volume.drivers.emc.scaleio [req-5c0a7619-898b-44b8-bc47-3879195b2de3 - - - - -] username: admin, verify_cert: False. 2017-09-22 12:13:48.945 527107 WARNING py.warnings [req-5c0a7619-898b-44b8-bc47-3879195b2de3 - - - - -] /usr/lib/python2.7/site-packages/requests/packages/urllib3/connectionpool.py:821: InsecureRequestWarning: Unverified HTTPS request is being made.
