Bug Description
When attempting to do a live-migration on an instance with one or more attached volumes, Nova expects that the IQN will be exactly the same as it's attaching the volume(s) to the new host. This conflicts with the Cinder settings such as "hp3par_iscsi_ips" which allows for multiple IPs for the purpose of load balancing.
An instance on Host A has a volume attached at "/dev/disk/
An attempt is made to migrate the instance to Host B.
Cinder sends the request to attach the volume to the new host.
Cinder gives the new host "/dev/disk/
Nova looks for the volume on the new host at the old location "/dev/disk/
The following error appears in n-cpu in this case:
