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
	You must override the default value of netapp_storage_protocol with iscsi in order to utilize the iSCSI protocol.

Table 1.17. Description of configuration options for netapp_7mode_iscsi

Configuration option = Default value	Description
[DEFAULT]
netapp_login = None	(StrOpt) Administrative user account name used to access the storage system or proxy server.
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 = 80	(IntOpt) The TCP port to use for communication with the storage system or proxy server. Traditionally, port 80 is used for HTTP and port 443 is used for HTTPS; however, this value should be changed if an alternate port has been configured on the storage system or proxy server.
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; valid values are iscsi or nfs.
netapp_transport_type = http	(StrOpt) The transport protocol used when communicating with the storage system or proxy server. Valid values are http or https.
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 and the storage protocol selected is iSCSI. 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. 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.
