NetApp iSCSI configuration for clustered Data ONTAP

The NetApp iSCSI configuration for clustered Data ONTAP is an interface from OpenStack to clustered Data ONTAP 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 clustered Data ONTAP is a direct interface from OpenStack Block Storage to the clustered Data ONTAP instance and as such does not require additional management software to achieve the desired functionality. It uses NetApp APIs to interact with the clustered Data ONTAP instance.

 Configuration options for clustered Data ONTAP family with iSCSI protocol

Configure the volume driver, storage family and storage protocol to the NetApp unified driver, clustered Data ONTAP, 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_cluster
  netapp_storage_protocol=iscsi
  netapp_vserver=openstack-vserver
  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 1.14. Description of configuration options for netapp_cdot_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_vserver = None	(StrOpt) This option specifies the virtual storage server (Vserver) name on the storage cluster on which provisioning of block storage volumes should occur. If using the NFS storage protocol, this parameter is mandatory for storage service catalog support (utilized by Cinder volume type extra_specs support). If this option is specified, the exports belonging to the Vserver will only be used for provisioning in the future. Block storage volumes on exports not belonging to the Vserver specified by this option will continue to function normally.

	Note
	If you specify an account in the netapp_login that only has virtual storage server (Vserver) administration privileges (rather than cluster-wide administration privileges), some advanced features of the NetApp unified driver will not work and you may see warnings in the OpenStack Block Storage logs.
