NetApp iSCSI configuration for E-Series

The NetApp iSCSI configuration for E-Series is an interface from OpenStack to E-Series storage systems for provisioning and managing the SAN block storage entity; that is, a NetApp LUN which can be accessed using the iSCSI protocol.

The iSCSI configuration for E-Series is an interface from OpenStack Block Storage to the E-Series proxy instance and as such requires the deployment of the proxy instance in order to achieve the desired functionality. The driver uses REST APIs to interact with the E-Series proxy instance, which in turn interacts directly with the E-Series controllers.

Configuration options for E-Series storage family with iSCSI protocol

Configure the volume driver, storage family and storage protocol to the NetApp unified driver, E-Series, 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=eseries
  netapp_storage_protocol=iscsi
  netapp_server_hostname=myhostname
  netapp_server_port=80
  netapp_login=username
  netapp_password=password
  netapp_controller_ips=1.2.3.4,5.6.7.8
  netapp_sa_password=arrayPassword
  netapp_storage_pools=pool1,pool2

	Note
	You must override the default value of `netapp_storage_family` with `eseries` in order to utilize the E-Series driver.

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

Table 1.19. Description of configuration options for netapp_eseries_iscsi
Configuration option = Default value	Description
[DEFAULT]
netapp_controller_ips = None	(StrOpt) This option is only utilized when the storage family is configured to eseries. This option is used to restrict provisioning to the specified controllers. Specify the value of this option to be a comma separated list of controller hostnames or IP addresses to be used for provisioning.
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_sa_password = None	(StrOpt) Password for the NetApp E-Series storage array.
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_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_pools = None	(StrOpt) This option is used to restrict provisioning to the specified storage pools. Only dynamic disk pools are currently supported. Specify the value of this option to be a comma separated list of disk pool names to be used for provisioning.
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_webservice_path = /devmgr/v2	(StrOpt) This option is used to specify the path to the E-Series proxy application on a proxy server. The value is combined with the value of the netapp_transport_type, netapp_server_hostname, and netapp_server_port options to create the URL used by the driver to connect to the proxy application.
