- Version history:
- 1.0.0 - Initial driver
1.0.1 - Support DS4000
-
check_for_setup_error()
-
create_cloned_volume(volume, src_vref)
Creates a clone of the specified volume.
-
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.
-
create_volume_from_snapshot(volume, snapshot)
Creates a volume from a snapshot.
-
delete_snapshot(snapshot)
Deletes a snapshot.
-
delete_volume(volume)
Deletes a volume.
-
ensure_export(context, volume)
Synchronously recreates an export for a volume.
-
extend_volume(volume, new_size)
Extend a volume.
-
get_volume_stats(refresh=False)
Get volume stats.
If ‘refresh’ is True, run update the stats first.
-
initialize_connection(*args, **kwargs)
-
manage_existing(volume, existing_ref)
Manage an existing lun in the array.
The lun should be in a manageable pool backend, otherwise
error would return.
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.
- existing_ref:{
- ‘id’:lun_id
}
-
manage_existing_get_size(volume, existing_ref)
Return size of volume to be managed by manage_existing.
When calculating the size, round up to the next GB.
-
migrate_volume(ctxt, volume, host)
Migrate the volume to the specified host.
Returns a boolean indicating whether the migration occurred, as well as
model_update.
| Parameters: |
- ctxt – Context
- volume – A dictionary describing the volume to migrate
- host – A dictionary describing the host to migrate to, where
host[‘host’] is its name, and host[‘capabilities’] is a
dictionary of its reported capabilities.

-
remove_export(context, volume)
Removes an export for a volume.
-
retype(ctxt, volume, new_type, diff, host)
Convert the volume to be of the new type.
| Parameters: |
- ctxt – Context
- volume – A dictionary describing the volume to migrate
- new_type – A dictionary describing the volume type to convert to
- diff – A dictionary with the difference between the two types
- host – A dictionary describing the host to migrate to, where
host[‘host’] is its name, and host[‘capabilities’] is a
dictionary of its reported capabilities.

-
terminate_connection(*args, **kwargs)
-
unmanage(volume)
Removes the specified volume from Cinder management.
Does not delete the underlying backend storage object.
| Parameters: | volume – Cinder volume to unmanage |
|---|
-
update_migrated_volume(ctxt, volume, new_volume, original_volume_status)
Return model update for migrated volume.
| Parameters: |
- 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
