Public bug reported:

When live migration is performed on instances with volume attached, nova
sends two initiator commands and one terminate connection. This causes
orphan access records in some storage arrays ( tested with Dell
EqualLogic Driver).

Steps to reproduce:
1. Have one controller and two compute node setup. Setup cinder volume on iscsi or a storage array.
2. Create an instance
3. Create a volume and attach it to the instance
4. Check the location of the instance ( computenode1 or 2)
nova instance1 show
4. Perform live migration of the instance and move it to the second compute node
nova live-migration instance1 computenode2
5. Check the cinder api log. c-api
There will be two os-initialize_connection and one os-terminate-connection. There should only be one set of initialize and terminate connection
