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 ** Affects: cinder Importance: Undecided Status: New ** Affects: nova Importance: Undecided Status: New ** Tags: cinder live-migration nova ** Description changed: When live migration is performed on instances with volume attached, nova - sends two initiator commands and one ter5.minate connection.
