Description of problem:
Note: Customer is using EMCDell VNX as a cinder driver. But we'd like to make sure this issue is not raised from OpenStack side
Volume attachment is failing, on Cinder it shows as available but nova shows it as attached.
I'll post more information and logs on the next comment as private, since it may contain customer sensitive information.
We're expecting a RCA from this issue.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
sosreport are available on supportshell under /cases/02791747
Do we currently have any workaround for this issue? Or maybe just to mitigate, like increasing some timeout?

There's no workaround at present, we have spoken about removing this initial RPC call entirely and creating the bdm record in the DB from within the API for sometime to avoid the fallout we are seeing here from the timeout.
That said the underlying issue here seems to be more of a RPC issue so lets address that and I might spawn a separate bug to track the additional rework/refactor in openstack-nova.
