Multiple pools support SmartX support Volume migration support Volume retype support FC zone enhancement

VERSION = '1.1.1'

get_volume_stats(refresh=False)

Get volume status.

initialize_connection(*args, **kwargs)

terminate_connection(*args, **kwargs)

class Huawei18000ISCSIDriver(*args, **kwargs)

Bases: cinder.volume.drivers.huawei.huawei_driver.HuaweiBaseDriver, cinder.volume.driver.ISCSIDriver

ISCSI driver for Huawei OceanStor 18000 storage arrays.

Version history:

1.0.0 - Initial driver 1.1.0 - Provide Huawei OceanStor 18000 storage volume driver 1.1.1 - Code refactor

CHAP support Multiple pools support ISCSI multipath support SmartX support Volume migration support Volume retype support

VERSION = '1.1.1'

get_volume_stats(refresh=False)

Get volume status.

initialize_connection(*args, **kwargs)

Map a volume to a host and return target iSCSI information.

terminate_connection(*args, **kwargs)

Delete map between a volume and a host.

class HuaweiBaseDriver(*args, **kwargs)

Bases: cinder.volume.driver.VolumeDriver

check_for_setup_error()

Check configuration file.

create_cloned_volume(volume, src_vref)

Clone a new volume from an existing volume.

create_export(context, volume, connector)

Export a volume.

create_snapshot(*args, **kwargs)

create_volume(*args, **kwargs)

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(*args, **kwargs)

delete_volume(*args, **kwargs)

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(*args, **kwargs)

Extend a volume.

get_lun_specs(lun_id)

get_volume_stats(refresh=False)

Get volume status.

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_qos_lun(lun_id, qos_id)

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

Convert the volume to be of the new type.

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