class models.device_tree_details.DeviceTreeDetails(combine_method=None, device_length=None, device_nodes=None, stripe_size=None)[source]

Bases: object

Implementation of the ‘DeviceTreeDetails’ model.

Specifies a logical volume stored as a tree where the leaves are the blocks of partitions and intermediate nodes are assembled by combining nodes using one of the following modes: linear layout, striped, mirrored, RAID etc. A deviceTree is a block device formed by combining one or more Devices using a combining strategy.

combine_method (CombineMethodEnum): Specifies how to combine the

children of this node. The combining strategy for child devices. Some of these strategies imply constraint on the number of child devices. e.g. RAID5 will have 5 children. ‘LINEAR’ indicates children are juxtaposed to form this device. ‘STRIPE’ indicates children are striped. ‘MIRROR’ indicates children are mirrored. ‘RAID5’ ‘RAID6’ ‘ZERO’ ‘THIN’ ‘THINPOOL’ ‘SNAPSHOT’ ‘CACHE’ ‘CACHEPOOL’

device_length (long|int): Specifies the length of this device. This

number should match the length that is calculated from the children and combining method.

device_nodes (list of DeviceNode): Specifies the children of this node

in the device tree.

stripe_size (int): Specifies the size of the striped data if the data

is striped.

classmethod from_dictionary(dictionary)[source]

Creates an instance of this model from a dictionary


dictionary (dictionary): A dictionary representation of the object as obtained from the deserialization of the server’s response. The keys MUST match property names in the API description.


object: An instance of this structure class.
