The NetApp unified driver for clustered Data ONTAP with share server management is a driver interface from OpenStack Manila to NetApp clustered Data ONTAP storage controllers to accomplish provisioning and management of shared file systems across the scope of the entire cluster. This driver will create a new storage virtual machine (SVM) for each share server that is requested by the Manila service. This driver also creates new data logical interfaces (LIFs) that provide access for clients on a specific share network to access shared file systems exported from the share server.
To set up the NetApp clustered Data ONTAP driver with Share Server management, the following stanza should be added to the Manila configuration file (manila.conf
):
[cdotMultipleSVM] share_backend_name=cdotMultipleSVM share_driver=manila.share.drivers.netapp.common.NetAppDriver driver_handles_share_servers=True netapp_storage_family=ontap_cluster netapp_server_hostname=hostname
netapp_server_port=80
netapp_login=admin_username

Table 6.14, “Configuration options for clustered Data ONTAP with Share Server management” lists the configuration options available for the unified driver for a clustered Data ONTAP deployment that manages share servers.
Option | Type | Default Value | Description |
driver_handles_share_servers |
Required | Denotes whether the driver should handle the responsibility of managing share servers. This must be set to true if the driver is to manage share servers. |
|
netapp_server_hostname |
Required | The hostname or IP address for the storage system or proxy server. The value of this option should be the IP address of the cluster management LIF. | |
netapp_server_port |
Optional | The TCP port to use for communication with the storage system or proxy server. If not specified, Data ONTAP drivers will use 80 for HTTP and 443 for HTTPS. | |
netapp_login |
Required | Administrative user account name used to access the storage system. | |
netapp_password |
Required | Password for the administrative user account specified in the netapp_login option. |
|
netapp_transport_type |
Required | http |
Transport protocol for communicating with the storage system or proxy server. Valid options include http and https . |
netapp_storage_family |
Required | ontap_cluster |
The storage family type used on the storage system; valid values are ontap_cluster for clustered Data ONTAP. |
netapp_root_volume_aggregate |
Required | This option specifies name of the aggregate upon which the root volume should be placed when a new SVM is created to correspond to a Manila share server. | |
netapp_root_volume_name |
Optional | root |
This option specifies name of the root volume that will be created when a new SVM is created to correspond to a Manila share server. |
netapp_vserver_name_template |
Optional | os_%s |
This option specifies a string replacement template that is applied when naming SVMs that are created to correspond to a Manila share server. |
netapp_lif_name_template |
Optional | os_%(net_allocation_id)s |
This option specifies a string replacement template that is applied when naming data LIFs that are created as a result of provisioning requests. |
netapp_volume_name_template |
Optional | share_%(share_id)s |
This option specifies a string replacement template that is applied when naming FlexVol volumes that are created as a result of provisioning requests. |
netapp_volume_snapshot_reserve_percent |
Optional | 5 |
This option specifies the percentage of share space set aside as reserve for snapshot usage. Valid values range from 0 to 90. |
netapp_aggregate_name_search_pattern |
Optional | (.*) |
This option specifies a regular expression that is applied against all available aggregates. This filtered list will be reported to the Manila scheduler as valid pools for provisioning new shares. |
netapp_port_name_search_pattern |
Optional | (.*) |
This option allows you to specify a regular expression for overriding the selection of network ports on which to create Vserver LIFs. |
netapp_trace_flags |
Optional | This option is a comma-separated list of options (valid values include method and api ) that controls which trace info is written to the Manila logs when the debug level is set to True . |

When defining Neutron subnets (Liberty or prior) with Clustered Data ONTAP, overlapping IP ranges should not be allowed. Using overlapping IP ranges in Neutron can cause a failure when a new Share Server is created. |
