create_cloned_volume(volume, src_vref)¶

Creates cloned volume.

1. Take an internal snapshot of source volume, and attach it.
2. Thin clone from the snapshot to a new volume. Note: there are several cases the thin clone will downgrade to dd, 2.1 Source volume is attached (in-use). 2.2 Array OE version doesn’t support thin clone. 2.3 The current LUN family reaches the thin clone limits.
3. Delete the internal snapshot created in step 1.

create_snapshot(snapshot)¶

Creates a snapshot.

Parameters:	snapshot – snapshot information.

create_volume(volume)¶

Creates a volume.

Parameters:	volume – volume information

create_volume_from_snapshot(volume, snapshot)¶

delete_snapshot(snapshot)¶

Deletes a snapshot.

Parameters:	snapshot – the snapshot to delete.

delete_volume(volume)¶

do_setup(driver, conf)¶

driver_name = ‘UnityAbstractDriver’¶

driver_volume_type = ‘unknown’¶

extend_volume(volume, new_size)¶

get_all_ports()¶

get_connection_info(hlu, host, connector)¶

get_connector_uids(connector)¶

get_lun_id(volume)¶

Retrieves id of the volume’s backing LUN.

Parameters:	volume – volume information

get_managed_pools()¶

get_pool_name(volume)¶

get_pools_stats()¶

initialize_connection(*args, **kwargs)¶

initialize_connection_snapshot(*args, **kwargs)¶

makeup_model(lun, is_snap_lun=False)¶

manage_existing(volume, existing_ref)¶

Manages an existing LUN in the array.

The LUN should be in a manageable pool backend, otherwise return error. 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.

LUN ID or name are supported in existing_ref, like:

existing_ref:{

‘source-id’:<LUN id in Unity>

}

or

existing_ref:{

‘source-name’:<LUN name in Unity>

}

manage_existing_get_size(volume, existing_ref)¶

Returns size of volume to be managed by manage_existing.

The driver does some check here: 1. The LUN existing_ref should be managed by the volume.host.
