Are there anyone who are using EMC VNX storage?
I'm facing the problem when I did ""nova evacute"" then ""cinder delete""
to delete volume,
I always failed to delete the volume:

203636 2015-11-16 20:44:31.924 26528 ERROR oslo.messaging.rpc.dispatcher
[req-93b20dc9-e91d-47ef-a78b-fcae3fa89576 cd53aa6989f3465b8c252451a378c665
d402f017e8594eb8ac8ee08250ee5289 - - -] Exception during message handling:
Bad or unexpected response from the storage volume backend API:

'-o'] (Return Code: 156) (Output: [u"Cannot unbind LUN because it's
contained in a Storage Group\\n"])

Is that driver issue, or some kind of VNX integration with OpenStack?
Or is there any manual operation necessary?

What do you think?

Thank you,
