NetApp iSCSI direct driver for 7-Mode storage controller

The NetApp iSCSI direct driver for 7-Mode is a driver interface from OpenStack to the NetApp 7-Mode storage controllers for the provisioning and managing the SAN block storage entity, that is, NetApp LUN using iSCSI protocol.

The NetApp iSCSI direct driver for 7-Mode does not require any additional management software to achieve the desired functionality. It uses NetApp APIs to interact with the 7-Mode storage controller.

Configuration options for the 7-Mode direct driver

Set the volume driver to the NetApp 7-Mode direct driver by setting the volume_driver option in cinder.conf as follows:

  volume_driver=cinder.volume.drivers.netapp.iscsi.NetAppDirect7modeISCSIDriver

Table 11.4. List of configuration flags for NetApp 7-Mode iSCSI direct driver
Flag name	Type	Default	Description
`netapp_server_hostname`	Mandatory		The management IP address for the 7-Mode storage controller.
`netapp_server_port`	Mandatory		The 7-Mode controller port to use for communication. As a custom 80 is used for http and 443 is used for https communication. The default ports can be changed if other ports are used for ONTAPI® on 7-Mode controller.
`netapp_login`	Mandatory		Login user name for 7-Mode controller management.
`netapp_password`	Mandatory		Login password for 7-Mode controller management.
`netapp_transport_type`	Optional	http	Transport protocol to use for communicating with 7-Mode controller. Supported protocols include http and https.
`netapp_size_multiplier`	Optional	1.2	The quantity to be multiplied by the requested OpenStack volume size which then is used to make sure that the final size is available on the 7-Mode controller before creating the OpenStack volume on the same controller.
`netapp_vfiler`	Optional		The vFiler unit to be used for provisioning of OpenStack volumes. Use this only if using MultiStore®.
`netapp_volume_list`	Optional		Comma separated list of NetApp volumes to be used for provisioning on 7-Mode controller. This option is used to restrict provisioning to the specified NetApp controller volumes. In case this option is not specified all NetApp controller volumes except the controller root volume are used for provisioning OpenStack volumes.
