Managed Object - VirtualDiskManager(vim.VirtualDiskManager)

Property of: ServiceContent
See also: Datacenter, HostDiskDimensionsChs, VirtualDiskSpec, VirtualMachineProfileSpec
Since: VI API 2.5

Managed Object Description

Most VirtualDiskManager APIs will be DEPRECATED as of vSphere 6.5. Please use VStorageObjectManager APIs to manage Virtual disks.

This managed object type provides a way to manage and manipulate virtual disks on datastores. The source and the destination names are in the form of a URL or a datastore path.

A URL has the form

scheme://authority/folder/path?dcPath=dcPath&dsName=dsName

where

scheme is http or https.
authority specifies the hostname or IP address of the VirtualCenter or ESX server and optionally the port.
dcPath is the inventory path to the Datacenter containing the Datastore.
dsName is the name of the Datastore.
path is a slash-delimited path from the root of the datastore.

A datastore path has the form

[datastore] path

where

datastore is the datastore name.
path is a slash-delimited path from the root of the datastore.

An example datastore path is "[storage] path/to/file.extension". A listing of all the files, disks and folders on a datastore can be obtained from the datastore browser.
See HostDatastoreBrowser

ShrinkVirtualDisk_Task(shrinkVirtualDisk)

Deprecated. as of vSphere 6.5, use ShrinkDisk_Task instead.
