Title:
volume-detach fails for shelved instance
Status in OpenStack Compute (nova):
In Progress
Status in OpenStack Compute (nova) mitaka series:
Confirmed
Bug description:
nova/compute/api.py::_local_cleanup_bdm_volumes passes a fake
connector to Cinder to ask it to terminate a connection to a volume.
Many Cinder volume drivers need a valid connector that has a real
'host' value in order to terminate the connection on the array.
The connector being passed in is:
'connector': {u'ip': u'127.0.0.1', u'initiator': u'iqn.fake'}
