Description Hervé Beraud 2021-03-17 14:35:12 UTC

This bug was initially created as a copy of Bug #1898578

I am copying this bug because: 

Backporting fixes to 16.2

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.
