NetApp Unified Driver for Clustered Data ONTAP with Fibre Channel

The NetApp unified driver for clustered Data ONTAP with Fibre Channel is a driver interface from OpenStack Cinder to NetApp clustered Data ONTAP storage controllers to accomplish provisioning and management of a storage-area network (SAN) block storage entity; that is, a NetApp LUN that uses the Fibre Channel protocol.

Configuration Options

To set up the NetApp clustered Data ONTAP Fibre Channel driver for Cinder, the following stanza should be added to the Cinder configuration file (cinder.conf):

[myFCBackend] 
volume_backend_name=myFCBackend
volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver
netapp_server_hostname=hostname
netapp_server_port=80
netapp_storage_protocol=fc 
netapp_storage_family=ontap_cluster
netapp_login=admin_username
netapp_password=admin_password
netapp_vserver=svm_name

	Be sure that the value of the `enabled_backends` option in the `[DEFAULT]` stanza includes the name of the stanza you chose for the backend.
	The value of `netapp_storage_protocol` MUST be set to `fc`.

Table 4.11, “Configuration options for clustered Data ONTAP with Fibre Channel” lists the configuration options available for the unified driver for a clustered Data ONTAP deployment that uses the Fibre Channel storage protocol.

Table 4.11. Configuration options for clustered Data ONTAP with Fibre Channel
Option	Type	Default Value	Description
`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; E-Series will use 8080 for HTTP and 8443 for HTTPS.
`netapp_login`	Required		Administrative user account name used to access the storage system or proxy server.
`netapp_password`	Required		Password for the administrative user account specified in the `netapp_login` option.
`netapp_storage_protocol`	Required		The storage protocol to be used. Valid options are `nfs`, `iscsi` or `fc`.
`netapp_transport_type`	Required	`http`	Transport protocol for communicating with the storage system or proxy server. Valid options include `http` and `https`.
`netapp_size_multiplier`	Optional	1.2	When creating volumes, the quantity to be multiplied to the requested OpenStack volume size to ensure enough space is available on the SVM (aka Vserver). This value is currently only used when iSCSI has been selected as the storage protocol to be used.
`netapp_vserver`	Required		This option specifies the storage virtual machine (previously called a Vserver) name on the storage cluster on which provisioning of block storage volumes should occur.
`netapp_storage_family`	Optional	`ontap_cluster`	The storage family type used on the storage system; valid values are `ontap_7mode` for Data ONTAP operating in 7-Mode, `ontap_cluster` for clustered Data ONTAP, or `eseries` for E-Series.

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 Cinder logs. See the section called “Account Permission Considerations” for more details on the required access level permissions for an SVM admin account.

	Important
	In order for Fibre Channel to be set up correctly, you also need to set up Fibre Channel zoning for your backends. See the section called “Fibre Channel Switch Fabric With Cinder” for more details on configuring Fibre Channel zoning.
