So the volume type error will require a copy of your cinder.conf. Or you can just verify you have a [SATA] section in it.
Also, volume type to my knowledge won’t change how libvirt presents the volume to the instance. I am not sure it can be changed, or at least never had to explore trying to do what you are needing to do.

I'm working on Liberty Openstack environment using ibm.storwize_svc.StorwizeSVCDriver as volume_drivert. When I'm creating a new volume and attaching it to the VM - by default it will be /dev/vdX on the instance using virtio driver. And this way everything is working fine. But I need it to be /dev/sdX for my application needs. I tried to create a new type of the volume by running : cinder type-create SATA cinder type-key SATA set volume_backend_name=sata But when I start a volume create process , it fails - the new volume has error state and the error in cinder-scheduler.log is : ERROR cinder.scheduler.flows.create_volume Failed to run task cinder.scheduler.flows.create_volume.ScheduleCreateVolumeTask;volume:create: No valid host was found. No weighed hosts available Please advise how a volume can be attached as /dev/sdX device and not /dev/vdX. The solution of stop the VM first and only then attach a volume can also be taken in account. Thank you.
