NetApp Unified Driver for Clustered Data ONTAP without Share Server management

The NetApp unified driver for clustered Data ONTAP without 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 within the scope of a single SVM (Vserver).

Configuration Options

To set up the NetApp clustered Data ONTAP driver without Share Server management, the following stanza should be added to the Manila configuration file (manila.conf):

[cdotSingleSVM] 
share_backend_name=cdotSingleSVM
share_driver = manila.share.drivers.netapp.common.NetAppDriver
driver_handles_share_servers=False 
netapp_storage_family=ontap_cluster
netapp_server_hostname=hostname
netapp_server_port=80
netapp_login=admin_username
netapp_password=admin_password
netapp_vserver=svm_name
netapp_transport_type=https
netapp_aggregate_name_search_pattern=^((?!aggr0).)*$

	Be sure that the value of the `enabled_share_backends` option in the `[DEFAULT]` stanza includes the name of the stanza you chose for the backend.
	The value of `driver_handles_share_servers` MUST be set to `False` if you want the driver to operate without managing share servers.

Table 6.13, “Configuration options for clustered Data ONTAP without Share Server management” lists the configuration options available for the unified driver for a clustered Data ONTAP deployment that does not manage share servers.

Table 6.13. Configuration options for clustered Data ONTAP without Share Server management
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 `false` if the driver is to operate without managing 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 either the cluster management LIF or the SVM 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_vserver`	Required		This option specifies the storage virtual machine (previously called a Vserver) name on the storage cluster on which provisioning of shared file systems should occur. This parameter is required if the driver is to operate without managing share servers (that is, be limited to the scope of a single SVM).
`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_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 related to the SVM specified in the `netapp_vserver` option. This filtered list will be reported to the Manila scheduler as valid pools for provisioning new shares.
`replication_domain`	Optional		This option specifies a string to identify a replication domain. Manila will allow all backends with the same replication domain to replicate to each other. If this is left blank, the backend will not support replication. If provided, all backends within the replication domain should have their configuration stanzas included in the backends configuration file. See the section called “`manila.conf` with Replication” for examples. Ensure all ONTAP clusters and SVMs within the replication domain are peered and have intercluster LIFs configured. See the section called “Data ONTAP Configuration”.
`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`.

Caution

	Caution
If you specify an account in the `netapp_login` option that only has SVM administration privileges (rather than cluster administration privileges), some advanced features of the NetApp unified driver will not work and you may see warnings in the Manila logs. See the section called “Account Permission Considerations” for more details on the required access level permissions for an SVM admin account.
