    Dell EMC VNX Driver: Fixes `bug 1817385
    <https://bugs.launchpad.net/cinder/+bug/1817385>`__ to make sure the sg can
    be created again after it was destroyed under `destroy_empty_storage_group`
    setting to `True`.
VNX: update sg in cache When `destroy_empty_storage_group` is enabled, the sg will be deleted after the last lun is detached from it. The issue is that the sg cache isn't updated, which caused the failure of subsequent attaching volumes to the same host because the sg in the cache will be used directly which doesn't exist any more. The fix is updating the sg with poll after deleting it. This doesn't delete the sg from cache explicitly but makes sure the sg in cache with latest status `not-exist`. Subsequent attaching will create the sg if it is `not-exist`. Closes-bug: #1817385 Change-Id: Ibb39879a77c97c6a5d885461e93116810d16b265 2019-02-25 17:43:46 +08:00			`---`
