FCTargetData
(volume_id, is_discovered, wwn=None, lun=None, initiator_target_map=None)¶Bases: dict
to_dict
()¶Converts to the dict.
It helps serialize and deserialize the data before returning to nova.
Host
(name, initiators, ip=None, wwpns=None)¶Bases: object
The model of a host which acts as an initiator to access the storage.
ISCSITargetData
(volume_id, is_discovered, iqn=’unknown’, iqns=None, portal=’unknown’, portals=None, lun=’unknown’, luns=None)¶Bases: dict
to_dict
()¶Converts to the dict.
It helps serialize and deserialize the data before returning to nova.
PoolState
¶Bases: object
DELETING
= ‘Deleting’¶INITIALIZING
= ‘Initializing’¶OFFLINE
= ‘Offline’¶VALID_CREATE_LUN_STATE
= (‘Initializing’, ‘Offline’, ‘Deleting’)¶ReplicationDevice
(replication_device)¶Bases: object
backend_id
¶pool_name
¶san_ip
¶san_login
¶san_password
¶storage_vnx_authentication_type
¶storage_vnx_security_file_dir
¶ReplicationDeviceList
(configuration)¶Bases: list
Replication devices configured in cinder.conf
Cinder supports multiple replication_device, while VNX driver only support one replication_device for now.
devices
¶get_backend_ids
(config)¶Returns all configured device_id.
get_device
(backend_id)¶next
()¶parse_configuration
()¶VNXEnablerStatus
(dedup=False, compression=False, fast=False, thin=False, snap=False)¶Bases: object

(mirror_name)¶delete_mirror_group
(group_name)¶delete_secondary_lun
(lun_name)¶destroy_mirror
(mirror_name, secondary_lun_name)¶Destroy the mirror view’s related VNX objects.
NOTE: primary lun will not be deleted here. :param mirror_name: name of mirror to be destroyed :param secondary_lun_name: name of LUN name
fracture_image
(mirror_name)¶fracture_mirror_group
(group_name)¶promote_image
(mirror_name)¶Promote the image on the secondary array.
promote_mirror_group

(group_name)¶Volume
(name, id, vnx_lun_id=None)¶Bases: object
The internal volume which is used to pass in method call.
WaitUtilTimeoutException
