The cinder.volume.drivers.emc.emc_smis_iscsi Module

ISCSI Drivers for EMC VNX and VMAX arrays based on SMI-S.

class EMCSMISISCSIDriver(*args, **kwargs)

Bases: cinder.volume.driver.ISCSIDriver

EMC ISCSI Drivers for VMAX and VNX using SMI-S.

check_for_export(context, volume_id)

Make sure volume is exported.

check_for_setup_error()

create_cloned_volume(volume, src_vref)

Creates a cloned volume.

create_export(context, volume)

Driver entry point to get the export info for a new volume.

create_snapshot(snapshot)

Creates a snapshot.

create_volume(volume)

Creates a EMC(VMAX/VNX) volume.

create_volume_from_snapshot(volume, snapshot)

Creates a volume from a snapshot.

delete_snapshot(snapshot)

Deletes a snapshot.

delete_volume(volume)

Deletes an EMC volume.

ensure_export(context, volume)

Driver entry point to get the export info for an existing volume.

get_volume_stats(refresh=False)

Get volume status.

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,
    }
}

remove_export(context, volume)

Driver entry point to remove an export for a volume.

terminate_connection(volume, connector, **kwargs)

Disallow connection from connector.

update_volume_status()

Retrieve status info from volume group.
