Virtual Infrastructure Http Nfc Lease APIs

• Virtual Infrastructure

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](../../sdk/vim25/release/HttpNfcLease/moId/info/get) property to determine where to up/download disks. The client must call [HttpNfcLeaseProgress](../../sdk/vim25/release/HttpNfcLease/moId/HttpNfcLeaseProgress/post) 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](../../sdk/vim25/release/HttpNfcLease/moId/HttpNfcLeaseComplete/post) 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](../../sdk/vim25/release/HttpNfcLease/moId/HttpNfcLeaseAbort/post). In this state, the [error](../../sdk/vim25/release/HttpNfcLease/moId/error/get) 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.
