Cannot add volumes to consistency group

Mirantis OS9 (Mitaka) environment.
Ubuntu 14.04
One Controller/Cinder Node
Two Compute Nodes

I'm unable to add volumes to a consistency group. I created a consistency group.

cinder consisgroup-list
+--------------------------------------+-----------+------------+
| ID | Status | Name |
+--------------------------------------+-----------+------------+
| 3fa309fe-d652-48d2-a02a-0b2d3833d994 | available | vamx-v3-CG |

I attempted to add a volume to the consistency group.

cinder create --volume-type vmax_1559_fc --name vmax-v3-cg-vol-2 --consisgroup-id 3fa309fe-d652-48d2-a02a-0b2d3833d994 60

The volume add/creation errors almost immediately upon submission every time.

I manually created the volume and attempted to add the volume using the Horizon User interface and received an error message " Unable to edit consistency group"

Cinder logs attached.

Please attach diagnostic snapshot.

[Ganesh (trinadhganesh-veeravalli)]

We have generated the diagnostic snapshot, but the snapshot is 2.8GB in size. Please let us know any location where we can upload the file as its too large to attach it here

[Oleksiy Molchanov (omolchanov)]

Paul, please upload them to google drive.

After applying a patch to the EMC VMAX Cinder driver form emcgit I'm no longer able to reproduce the issue. The patch has resolved the problem.

[Oleksiy Molchanov (omolchanov)]

Paul, can you provide us with url to that patch? Thanks in advance.
