NetApp Unified Driver for Data ONTAP operating in 7-Mode with iSCSI

The NetApp unified driver for Data ONTAP operating in 7-Mode with iSCSI is a driver interface from OpenStack Cinder to NetApp Data ONTAP operating in 7-Mode storage controllers to accomplish provisioning and management of a storage-area network (SAN) block storage entity; that is, a NetApp LUN that uses the iSCSI protocol.

Configuration Options

To set up the NetApp Data ONTAP operating in 7-Mode iSCSI driver for Cinder, the following stanza should be added to the Cinder configuration file (cinder.conf):

[myIscsiBackend] 
volume_backend_name=myIscsiBackend
volume_driver=cinder.volume.drivers.netapp.common.NetAppDriver
netapp_server_hostname=hostname
netapp_server_port=80
netapp_storage_protocol=iscsi  
netapp_storage_family=ontap_7mode 
netapp_login=admin_username
netapp_password=admin_password

	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 `iscsi`, as the default value for this option is `nfs`.
	The value of `netapp_storage_family` MUST be set to `ontap_7mode`, as the default value for this option is `ontap_cluster`.

Table 4.10, “Configuration options for Data ONTAP operating in 7-Mode with iSCSI” lists the configuration options available for the unified driver for a clustered Data ONTAP deployment that uses the iSCSI storage protocol.

Table 4.10. Configuration options for Data ONTAP operating in 7-Mode with iSCSI
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	`nfs`	The storage protocol to be used. Valid options are `nfs` or `iscsi`. If None is specified or the option is omitted, `nfs` will be used.
`netapp_transport_type`	Optional	`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_volume_list`	Optional		This option is only utilized when the storage protocol is configured to use iSCSI. This option is used to restrict provisioning to the specified controller volumes. Specify the value of this option to be a comma separated list of NetApp controller volume names to be used for provisioning.
`netapp_vfiler`	Optional		The vFiler unit on which provisioning of block storage volumes will be done. This option is only used by the driver when connecting to an instance with a storage family of Data ONTAP operating in 7-Mode. Only use this option when utilizing the MultiStore feature on the NetApp storage system.
`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.
