Async migration is used in the process of creating a volume from a snapshot and an internal temp snapshot is created. Because the temp snapshot isn't deleted, the LUN hosting the temp snapshot cannot be deleted from the VNX storage. For example, a new volume, V2, is created from snapshot S1 of volume V1. An internal temp snapshot S2 is created from copying S1. V1 now has two snapshots, S1 and S2. Although we delete V1, V2 and S1 from Cinder, S2 which is Cinder user-invisible isn't deleted and which causes V1 left on VNX too. The fix makes sure the snapshot S2 is deleted. Then the delay deletion on V1 can be executed successfully. Change-Id: Ib86729488ebfb0aea5d5d4f815a64e00258040e7 Closes-bug: #1794646

Dell EMC VNX Cinder Driver: Fixes `bug 1794646
|
|
<https://bugs.launchpad.net/cinder/+bug/1794646>`__ to delete the LUN from
|
|
the VNX storage. Because a temporary snapshot is created from the LUN
|
|
during creating a volume from a snapshot and isn't deleted, the LUN cannot
|
|
be deleted before its snapshot is deleted. The fix makes sure the temp
|
|
snapshot is deleted.
