class HuaweiBaseDriver(*args, **kwargs)

Bases: cinder.volume.driver.VolumeDriver

check_for_setup_error()

create_cloned_volume(volume, src_vref)

Clone a new volume from an existing volume.

create_export(context, volume, connector)

Export a volume.

create_snapshot(snapshot)

create_volume(volume)

Create a volume.

create_volume_from_snapshot(volume, snapshot)

Create a volume from a snapshot.

We use LUNcopy to copy a new volume from snapshot. The time needed increases as volume size does.

delete_snapshot(snapshot)

delete_volume(volume)

Delete a volume.

Three steps: Firstly, remove associate from lungroup. Secondly, remove associate from QoS policy. Thirdly, remove the lun.

determine_changes_when_retype(volume, new_type, host)

do_setup(context)

Instantiate common class and login storage system.

ensure_export(context, volume)

Synchronously recreate an export for a volume.

extend_volume(volume, new_size)

Extend a volume.

failover_host(context, volumes, secondary_id=None)

Failover all volumes to secondary.

get_local_and_remote_client_conf()

get_local_and_remote_dev_conf()

get_lun_specs(lun_id)

get_volume_stats(refresh=False)

Get volume status and reload huawei config file.

manage_existing(volume, external_ref)

Manage an existing volume on the backend storage.

manage_existing_get_size(volume, external_ref)

Get the size of the existing volume.

manage_existing_snapshot(snapshot, existing_ref)

manage_existing_snapshot_get_size(snapshot, existing_ref)

Get the size of the existing snapshot.

migrate_volume(ctxt, volume, host, new_type=None)

Migrate a volume within the same array.

modify_lun(lun_id, change_opts)

remove_export(context, volume)

Remove an export for a volume.

remove_host_with_check(host_id)

retype(ctxt, volume, new_type, diff, host)

Convert the volume to be of the new type.

unmanage(volume)

Export Huawei volume from Cinder.

unmanage_snapshot(snapshot)

Unmanage the specified snapshot from Cinder management.

update_migrated_volume(ctxt, volume, new_volume, original_volume_status=None)
