Integration with EMC UNITY Storage

Issue

• We are trying to integrate cinder and glance with EMC UNITY. We successfully connected our enviroment via API (using storops) in order do create volume by cinder but when cinder/glance wants to put some data via FiberChannel we have following error:

  2018-11-06 19:44:21.660 56 ERROR cinder.volume.manager   File "/usr/lib/python2.7/site-packages/cinder/volume/drivers/dell_emc/unity/adapter.py", line 317, in _initialize_connection

• also we run debug to see below output:

  me_type=<?>,volume_type_id=None), 'connector': {u'initiator': u'iqn.1994-05.com.redhat:de0a024fa7a', u'ip': u'controller-0', u'platform': u'x86_64', u'host': u'controller-0', u'do_local_attach': False, u'os_type': u'linux2', u'multipath': False}, 'self': <cinder.volume.drivers.dell_emc.unity.adapter.FCAdapter object at 0x7fd0f98ec390>} trace_logging_wrapper /usr/lib/python2.7/site-packages/cinder/utils.py:898
  

• we are using driver from here and also we tested driver provided in redhat OSP 13

• instalation guide:

• Looks cinder is not able to display information about FC from linux server.
