cinder.volume.drivers.nec.volume
Module¶Drivers for M-Series Storage.
MStorageFCDriver
(*args, **kwargs)¶Bases: cinder.volume.drivers.nec.volume_helper.MStorageDSVDriver
, cinder.volume.driver.FibreChannelDriver
M-Series Storage Snapshot FC Driver.
create_export
(context, volume, connector)¶Exports the volume.
Can optionally return a Dictionary of changes to the volume object to be persisted.
create_export_snapshot
(context, snapshot, connector)¶Exports the snapshot.
Can optionally return a Dictionary of changes to the snapshot object to be persisted.
ensure_export
(context, volume)¶Synchronously recreates an export for a volume.
get_volume_stats
(refresh=False)¶Get volume stats.
If ‘refresh’ is True, run update the stats first.
initialize_connection
(*args, **kwargs)¶initialize_connection_snapshot
(snapshot, connector, **kwargs)¶Allow connection from connector for a snapshot.
terminate_connection
(*args, **kwargs)¶terminate_connection_snapshot
(snapshot, connector, **kwargs)¶Disallow connection from connector for a snapshot.
MStorageISCSIDriver
(*args, **kwargs)¶Bases: cinder.volume.drivers.nec.volume_helper.MStorageDSVDriver
, cinder.volume.driver.ISCSIDriver
M-Series Storage Snapshot iSCSI Driver.
create_export
(context, volume, connector)¶Exports the volume.
Can optionally return a Dictionary of changes to the volume object to be persisted.
create_export_snapshot
(context, snapshot, connector)¶Exports the snapshot.
Can optionally return a Dictionary of changes to the snapshot object to be persisted.
ensure_export
(context, volume)¶Synchronously recreates an export for a volume.
get_volume_stats
(refresh=False)¶Get volume stats.
If ‘refresh’ is True, run update the stats first.
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': 1,
'discard': False,
}
}
If the backend driver supports multiple connections for multipath and for single path with failover, “target_portals”, “target_iqns”, “target_luns” are also populated:
{
'driver_volume_type': 'iscsi',
'data': {
'target_discovered': False,
'target_iqn': 'iqn.2010-10.org.openstack:volume1',
'target_iqns': ['iqn.2010-10.org.openstack:volume1',
'iqn.2010-10.org.openstack:volume1-2'],
'target_portal': '10.0.0.1:3260',
'target_portals': ['10.0.0.1:3260', '10.0.1.1:3260'],
'target_lun': 1,
'target_luns': [1, 1],
'volume_id': 1,
'discard': False,
}
}
initialize_connection_snapshot
(snapshot, connector, **kwargs)¶Allow connection from connector for a snapshot.
terminate_connection
(volume, connector, **kwargs)¶Disallow connection from connector

terminate_connection_snapshot
(snapshot, connector, **kwargs)¶Disallow connection from connector for a snapshot.
