In the OpenStack Havana release, NetApp deprecated a variety of management-integrated drivers that had been available in previous OpenStack releases. The driver names include:
cinder.volume.drivers.netapp.iscsi.NetAppCmodeISCSIDriver cinder.volume.drivers.netapp.nfs.NetAppCmodeNfsDriver cinder.volume.drivers.netapp.iscsi.NetAppISCSIDriver cinder.volume.drivers.netapp.nfs.NetAppNfsDriver
The direct (and now unified) driver available in the Havana release provides equivalent functionality to these drivers for the various OpenStack services, but without the complex configuration and requirements to operate additional management software and infrastructure.
In situations where it is necessary to leverage the management-integrated drivers in a Havana-based OpenStack deployment, NetApp has ported the drivers to the Havana code base and made them available for download from a separate git repository located at https://github.com/NetApp/cinder/tree/stable/havana.
