os_brick.exception.VolumeDeviceNotFound

[Dave West]

Running OpenStack 2023.2 with Cinder and PureStorage Flash Array as the backend. I am leveraging NVMe/TCP as the protocol. I am able to create a blank volume on the FA through Horizon. If I mark that volume as bootable and create an instance with it, or create a volume with an image, the volumes fail.

The most prevalent error I get is: "raise exception.VolumeDeviceNotFound(device=target.nqn)#0122023-12-24 18:22:36.440 53820 ERROR oslo_messaging.rpc.server os_brick.exception.VolumeDeviceNotFound: Volume device not found at nqn.2010-06.com.purestorage:flasharray"

When the workflow kicks off, I can see the volume mounted on the host.

I tried turning on debugging and verbose loggin to see the commands being sent to help understand where the process is failing, but unable to see that.
