cinder.volume.targets.iscsi module¶
-
class
ISCSITarget
(*args, **kwargs)¶ Bases:
cinder.volume.targets.driver.Target
Target object for block storage devices.
Base class for target object, where target is data transport mechanism (target) specific calls. This includes things like create targets, attach, detach etc.
-
create_export
(context, volume, volume_path)¶ Creates an export for a logical volume.
-
abstract
create_iscsi_target
(name, tid, lun, path, chap_auth, **kwargs)¶
-
ensure_export
(context, volume, volume_path)¶ Recreates an export for a logical volume.
-
extend_target
(volume)¶ Reinitializes a target after the LV has been extended.
Note: This will cause IO disruption in most cases.
-
initialize_connection
(volume, connector)¶ Initializes the connection and returns connection info.
The iscsi driver returns a driver_volume_type of ‘iscsi’. The format of the driver data is defined in _get_iscsi_properties. Example return value:
{ 'driver_volume_type': 'iscsi' 'data': { 'target_discovered': True, 'target_iqn': 'iqn.2010-10.org.openstack:volume-00000001', 'target_portal': '127.0.0.0.1:3260', 'volume_id': '9a0d35d0-175a-11e4-8c21-0800200c9a66', 'discard': False, } }
-
remove_export
(context, volume)¶ Removes an export for a Target/Volume.
-
abstract
remove_iscsi_target
(tid, lun, vol_id, vol_name, **kwargs)¶
-
show_target
(iscsi_target, iqn, **kwargs)¶
-
terminate_connection
(volume, connector, **kwargs)¶ Disallow connection from connector.
-
validate_connector
(connector)¶
-
-
class
SanISCSITarget
(*args, **kwargs)¶ Bases:
cinder.volume.targets.iscsi.ISCSITarget
iSCSI target for san devices.
San devices are slightly different, they don’t need to implement all of the same things that we need to implement locally fro LVM and local block devices when we create and manage our own targets.
