Failover Vcha Cluster Async

Initiates failover from the active vCenter node to the passive node. For forced failover, Active node immediately initiates a failover. This may result into a data loss after failover.

For planned failover, Active node flushes all the state to the Passive node, waits for the flush to complete before causing a failover. After the failover, Passive node starts without any data loss.

A failover is allowed only in the following cases:

Cluster's mode is enabled and all cluster members are present.
Cluster's mode is maintenance and all cluster members are present.

    "planned": false
}

boolean

planned

Required

If false, a failover is initiated immediately and may result in data loss. If true, a failover is initated after the Active node flushes its state to Passive and there is no data loss.

An identifier for the task created by this API invocation will be returned. If the non-async version of the operation returns a value, this id can be used with the CIS Get Task operation to fetch that value. The normal description of this operation's return value will follow if one exists.

array of Std_LocalizableMessage

messages

Required

Stack of one or more localizable messages for human error consumers. The message at the top of the stack (first in the list) describes the error from the perspective of the operation the client invoked.

Each subsequent message in the stack describes the "cause" of the prior message.

object

data

Optional

Data to facilitate clients responding to the operation reporting a standard error to indicating that it was unable to complete successfully. Operations may provide data that clients can use when responding to errors. Since the data that clients need may be specific to the context of the operation reporting the error, different operations that report the same error may provide different data in the error. The documentation for each each operation will describe what, if any, data it provides for each error it reports.

The ArgumentLocations, FileLocations, and TransientIndication structures are intended as possible values for this field. DynamicID may also be useful as a value for this field (although that is not its primary purpose). Some services may provide their own specific structures for use as the value of this field when reporting errors from their operations.

Some operations will not set this field when reporting errors.
