The cinder.volume.drivers.fusionstorage.dsware Module¶

Driver for Huawei FusionStorage.

class DSWAREDriver(*args, **kwargs)¶

Bases: cinder.volume.driver.VolumeDriver

Huawei FusionStorage Driver.

CI_WIKI_NAME = 'Huawei_FusionStorage_CI'¶

DSWARE_VOLUME_CREATE_SUCCESS_STATUS = 0¶

DSWARE_VOLUME_CREATING_STATUS = 7¶

DSWARE_VOLUME_DUPLICATE_VOLUME = 6¶

VERSION = '1.0'¶

check_for_setup_error()¶

copy_image_to_volume(context, volume, image_service, image_id)¶

Fetch image from image_service and write to unencrypted volume.

This does not attach an encryptor layer when connecting to the volume.

copy_volume_to_image(context, volume, image_service, image_meta)¶

Copy the volume to the specified image.

create_cloned_volume(volume, src_volume)¶

Dispatcher to Dsware client to create volume from volume.

Wait volume create finished.

create_export(context, volume, connector)¶

Exports the volume.

Can optionally return a Dictionary of changes to the volume object to be persisted.

create_snapshot(snapshot)¶

Creates a snapshot.

create_volume(volume)¶

Creates a volume.

Can optionally return a Dictionary of changes to the volume object to be persisted.

If volume_type extra specs includes ‘capabilities:replication <is> True’ the driver needs to create a volume replica (secondary), and setup replication between the newly created volume and the secondary volume. Returned dictionary should include:

volume['replication_status'] = 'copying'
volume['replication_extended_status'] = <driver specific value>
volume['driver_data'] = <driver specific value>

create_volume_from_snapshot(volume, snapshot)¶

Creates a volume from a snapshot.

If volume_type extra specs includes ‘replication: <is> True’ the driver needs to create a volume replica (secondary), and setup replication between the newly created volume and the secondary volume.

delete_snapshot(snapshot)¶

Deletes a snapshot.

delete_volume(volume)¶

Deletes a volume.

If volume_type extra specs includes ‘replication: <is> True’ then the driver needs to delete the volume replica too.

do_setup(context)¶

Any initialization the volume driver does while starting.

ensure_export(context, volume)¶

Synchronously recreates an export for a volume.

extend_volume(volume, new_size)¶

get_volume_stats(refresh=False)¶

Return the current state of the volume service.

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

For replication the following state should be reported: replication = True (None or false disables replication)

initialize_connection(volume, connector)¶

Initializes the connection and returns connection info.

remove_export(context, volume)¶

Removes an export for a volume.

terminate_connection(volume, connector, force=False, **kwargs)¶

Disallow connection from connector

Parameters:	volume – The volume to be disconnected. connector – A dictionary describing the connection with details about the initiator. Can be None.
