Managed Object Description

Represents a lease on a VirtualMachine or a VirtualApp, which can be used to import or export disks for the entity. While the lease is held, operations that alter the state of the virtual machines covered by the lease are blocked. Examples of blocked operations are PowerOn, Destroy, Migrate, etc.

A lease is in one of four states:

Initializing: This is the initial state. The lease remains in this state while the corresponding import/export task is preparing the objects. In an import session, this involves creating inventory objects.
Ready: The lease changes to this state once the corresponding import/export task is done preparing the lease. The leased objects are now ready, and the client can use the information provided in the info property to determine where to up/download disks. The client must call HttpNfcLeaseProgress periodically to keep the lease alive and report progress to the corresponding import/export task. Failure to do so causes the lease to time out and enter the error state.
Done: When the client is done transferring disks, it calls HttpNfcLeaseComplete to signal the end of the import/export session. This causes the corresponding import/export task to complete successfully.
Error: If an error occurs during initialization or the lease times out, it will change to this state. The client can also abort the lease manually by calling HttpNfcLeaseAbort. In this state, the error property can be read to determine the cause. If the lease belongs to an import session, all objects created during the import are removed when the lease enters this state.

The import/export task corresponding to the lease continues running while the lease is held.

Properties

Name	Type	Description
capabilities	HttpNfcLeaseCapabilities	Current supported capabilities by this lease See Capabilities *Since* vSphere API 6.7
error*	LocalizedMethodFault	If the lease is in the error state, this property contains the error that caused the lease to be aborted.
info*	HttpNfcLeaseInfo	Provides information on the objects contained in this lease. The info property is only valid when the lease is in the ready state.
initializeProgress	xsd:int	Provides progress information (0-100 percent) for the initializing state of the lease. Clients can use this to track overall progress.
mode	xsd:string	Current mode of the lease. See Mode for possible values. *Since* vSphere API 6.7
state	HttpNfcLeaseState	The current state of the lease.
transferProgress	xsd:int	Provides progress information (0-100 percent) for current transfer. Transfer covers download, upload and pull scenario. Can be externally updated by progress method. *Since* vSphere API 6.7

Methods

Methods defined in this Managed Object
HttpNfcLeaseAbort, HttpNfcLeaseComplete, HttpNfcLeaseGetManifest, HttpNfcLeaseProgress, HttpNfcLeasePullFromUrls_Task, HttpNfcLeaseSetManifestChecksumType

HttpNfcLeaseAbort(abort)

Aborts the import/export and releases this lease. Operations on the objects contained in this lease will no longer be blocked. After calling this method, this lease will no longer be valid.

Clients should call this method if an error occurs while accessing the disks, or if the operation is cancelled. The client can report the cause of the abort to other clients listening on the task with the fault parameter.

Required Privileges: None

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the HttpNfcLease used to make the method call.
fault*	MethodFault	[in] The fault that caused the abort, if any.

*Need not be set

Return Value

Type	Description
None

Faults

Type	Description
InvalidState	Thrown if the lease has already been aborted.
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.
Timedout	Thrown if the lease has timed out before this call.

HttpNfcLeaseComplete(complete)

Completes the import/export and releases this lease. Operations on the objects contained in this lease will no longer be blocked. After calling this method, this lease will no longer be valid.

Clients should call this method when they are done accessing the disks for the VirtualMachines in this lease. The status of the corresponding task will be set to success.
