Thank you for the prompt respond. 
How should  [SATA] section look in /etc/cinder/cinder.conf file ?

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.

Subject: [Openstack-operators] Cinder attach volume
Resent-From: Time Warner Cable

Hello. 
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.
