NetApp iSCSI configuration for Data ONTAP operating in 7-Mode

The NetApp iSCSI configuration for Data ONTAP operating in 7-Mode is an interface from OpenStack to Data ONTAP operating in 7-Mode storage systems for provisioning and managing the SAN block storage entity, that is, a LUN which can be accessed using iSCSI protocol.

The iSCSI configuration for Data ONTAP operating in 7-Mode is a direct interface from OpenStack to Data ONTAP operating in 7-Mode storage system and it does not require additional management software to achieve the desired functionality. It uses NetApp ONTAPI to interact with the Data ONTAP operating in 7-Mode storage system.

 Configuration options for the Data ONTAP operating in 7-Mode storage family with iSCSI protocol

Configure the volume driver, storage family and storage protocol to the NetApp unified driver, Data ONTAP operating in 7-Mode, and iSCSI respectively by setting the volume_driver, netapp_storage_family and netapp_storage_protocol options in cinder.conf as follows:

volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver
netapp_storage_family = ontap_7mode
netapp_storage_protocol = iscsi
netapp_server_hostname = myhostname
netapp_server_port = 80
netapp_login = username
netapp_password = password

	Note
	To use the iSCSI protocol, you must override the default value of netapp_storage_protocol with iscsi.

Table 2.21. Description of NetApp 7-Mode iSCSI driver configuration options

Configuration option = Default value	Description
[DEFAULT]
netapp_login = None	(StrOpt) Administrative user account name used to access the storage system or proxy server.
netapp_partner_backend_name = None	(StrOpt) The name of the config.conf stanza for a Data ONTAP (7-mode) HA partner. This option is only used by the driver when connecting to an instance with a storage family of Data ONTAP operating in 7-Mode, and it is required if the storage protocol selected is FC.
netapp_password = None	(StrOpt) Password for the administrative user account specified in the netapp_login option.
netapp_server_hostname = None	(StrOpt) The hostname (or IP address) for the storage system or proxy server.
netapp_server_port = None	(IntOpt) 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_size_multiplier = 1.2	(FloatOpt) The quantity to be multiplied by the requested volume size to ensure enough space is available on the virtual storage server (Vserver) to fulfill the volume creation request.
netapp_storage_family = ontap_cluster	(StrOpt) The storage family type used on the storage system; valid values are ontap_7mode for using Data ONTAP operating in 7-Mode, ontap_cluster for using clustered Data ONTAP, or eseries for using E-Series.
netapp_storage_protocol = None	(StrOpt) The storage protocol to be used on the data path with the storage system.
netapp_transport_type = http	(StrOpt) The transport protocol used when communicating with the storage system or proxy server.
netapp_vfiler = None	(StrOpt) 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_volume_list = None	(StrOpt) This option is only utilized when the storage protocol is configured to use iSCSI or FC. 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.
