Managed Object Description

NOTE: This managed object type and all of its methods are experimental and subject to change in future releases.

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.
