Comment 1 for bug 1175222

We just fixed this in the LHN driver and noticed it's a problem in a number of the drivers. We should just go through and address all of them at this point and submit one fix for all of the remaining drivers that didn't implement:

backend_name = self.configuration.safe_get('volume_backend_name')
data['volume_backend_name'] = backend_name or self.__class__.__name__
