Hello,
From the array, shutting down a controller and failing over the volume owned by the controller to the other controller is not an issue. That will happen smoothly.
More concering will be how the hosts are mapped to the system. As long as the hosts are mapped correctly so that all hosts have access to both controllers you will not have a disruption. My suggestion is to ensure the mapping is correct so the database associated with the volume owned by Controller B is also correctly mapped to the Controller A pathing. I would also confirm the multipathing is correct for the host(s) associated with that database to ensure a smooth failover.
Cheers,
Shawn
