The cinder.volume.drivers.nec.volume_helper Module¶

class MStorageDSVDriver¶

Bases: cinder.volume.drivers.nec.volume_helper.MStorageDriver

M-Series Storage Snapshot helper class.

create_snapshot(snapshot)¶

create_volume_from_snapshot(volume, snapshot)¶

delete_snapshot(snapshot)¶

class MStorageDriver¶

Bases: cinder.volume.drivers.nec.volume_common.MStorageVolumeCommon

M-Series Storage helper class.

backup_use_temp_snapshot()¶

check_for_export(context, volume_id)¶

create_cloned_volume(volume, src_vref)¶

create_volume(volume)¶

delete_volume(volume)¶

extend_volume(volume, new_size)¶

fc_do_export(_ctx, volume, connector, ensure=False)¶

fc_do_export_snapshot(context, snapshot, connector, ensure=False)¶

fc_get_volume_stats(refresh=False)¶

Get volume status.

If ‘refresh’ is True, run update the stats first.

fc_initialize_connection(volume, connector)¶

fc_initialize_connection_snapshot(snapshot, connector)¶

fc_terminate_connection(volume, connector)¶

fc_terminate_connection_snapshot(snapshot, connector, **kwargs)¶

get_manageable_snapshots(cinder_snapshots, marker, limit, offset, sort_keys, sort_dirs)¶

List snapshots on the backend available for management by Cinder.

get_manageable_volumes(cinder_volumes, marker, limit, offset, sort_keys, sort_dirs)¶

List volumes on the backend available for management by Cinder.

get_pool(volume)¶

iscsi_do_export(_ctx, volume, connector, ensure=False)¶

iscsi_do_export_snapshot(context, snapshot, connector)¶

Exports the snapshot.

iscsi_get_volume_stats(refresh=False)¶

Get volume status.

If ‘refresh’ is True, run update the stats first.

iscsi_initialize_connection(volume, connector)¶

iscsi_initialize_connection_snapshot(snapshot, connector, **kwargs)¶

Allow connection to connector and return connection info.

Parameters:	snapshot – The snapshot to be attached connector – Dictionary containing information about what is being connected to.
Returns conn_info:
	A dictionary of connection information. This can optionally include a “initiator_updates” field.

iscsi_terminate_connection(volume, connector)¶

iscsi_terminate_connection_snapshot(snapshot, connector, **kwargs)¶

Disallow connection from connector.

manage_existing(volume, existing_ref)¶

Brings an existing backend storage object under Cinder management.

Rename the backend storage object so that it matches the, volume[‘name’] which is how drivers traditionally map between a cinder volume and the associated backend storage object.

manage_existing_get_size(volume, existing_ref)¶

Return size of volume to be managed by manage_existing.

manage_existing_snapshot(snapshot, existing_ref)¶

Brings an existing backend storage object under Cinder management.

Rename the backend storage object so that it matches the snapshot[‘name’] which is how drivers traditionally map between a cinder snapshot and the associated backend storage object.

manage_existing_snapshot_get_size(snapshot, existing_ref)¶

Return size of snapshot to be managed by manage_existing.

migrate_volume(context, volume, host)¶

remove_export(context, volume)¶

remove_export_snapshot(context, snapshot)¶

Removes an export for a snapshot.

unmanage(volume)¶

Removes the specified volume from Cinder management.

unmanage_snapshot(snapshot)¶

Removes the specified snapshot from Cinder management.

update_migrated_volume(ctxt, volume, new_volume, original_volume_status)¶

Updates metadata after host-assisted migration.

This method should rename the back-end volume name(id) on the destination host back to its original name(id) on the source host.

Parameters:	ctxt – The context used to run the method update_migrated_volume volume – The original volume that was migrated to this backend new_volume – The migration volume object that was created on this backend as part of the migration process original_volume_status – The status of the original volume
Returns:	model_update to update DB with any needed changes
