ISCSI session remains after live migration of volume backed instance

[Hiroyuki Eguchi]

1.nova boot --flavor 1 --block_device_mapping vda=[volume_uuid]:[size]::0 --key_name key1 test_vm_0001

2.nova live-migration [instance_uuuid]

3.(in source host) iscsiadm -m session
tcp: [3] xxx.xxx.xxx.xxx:3260,1 iqn.2010-10.org.openstack:volume-[volume_uuid]

4.(in destination host) iscsiadm -m session
tcp: [3] xxx.xxx.xxx.xxx:3260,1 iqn.2010-10.org.openstack:volume-[volume_uuid]

I'm using cinder.volume.drivers.lvm.LVMISCSIDriver.

It seems that nova-compute try to delete session by using terminate_connection method in _post_live_migration,
but LVMISCSIDriver do nothing in terminate_connection method.

Nova should be nuking the session if it's the last LUN from that host. I've seen this happen when testing live migration with the 3par iscsi driver.

I believe this has been fixed since we added the terminate_connection calls to the detach methods. Closing for now, if somebody sees it still open it back up.

Closing stale bug. If this is still an issue please reopen.
