Managed Object - FailoverClusterConfigurator(vim.vcha.FailoverClusterConfigurator)

Property of: ServiceContent
See also: NodeDeploymentSpec, PassiveNodeDeploymentSpec, SourceNodeSpec, VchaClusterConfigInfo, VchaClusterConfigSpec, VchaClusterDeploymentSpec, VchaClusterNetworkSpec
Since: vSphere API 6.5

Managed Object Description

FailoverClusterConfigurator provides operations to create and configure a vCenter High Availability Cluster (VCHA Cluster). A VCHA Cluster consists of three VMs. One is the Active vCenter VM that serves client requests. Second is the Passive VM that is identical to the Active vCenter VM in terms of resources and capabilities. Passive VM constantly receives updates from Active VM and takes over the role of Active vCenter VM in the event of failover. Third is the Witness VM that acts as a quorum VM in a VCHA Cluster. Sole purpose of Witness VM is to avoid classic split-brain problem in a VCHA Cluster. A VCHA Cluster can be deployed in two possible ways - 1. Automatic deployment - Configuration (described below) inputs for each node in a VCHA Cluster is provided by the user. A Deployment workflow is used that automatically deploys Passive and Witness VM and configures each node to form a VCHA Cluster. 2. Manual deployment - User provisions and creates Passive and Witness VMs and uses Configuration workflow to configure Active, Passive and Witness VM to form a VCHA Cluster. Passive and Witness VMs must be created using the VM-Clone operation with Active VM as the source.

Methods

Methods defined in this Managed Object
configureVcha_Task, createPassiveNode_Task, createWitnessNode_Task, deployVcha_Task, destroyVcha_Task, getVchaConfig, prepareVcha_Task

configureVcha_Task(configure)

Configure VCHA on the local vCenter Server. This operation configures the VC appliance with VCHA specific inputs and uses already deployed Passive and Witness nodes to set up the VCHA cluster. After configuration, the VCHA Cluster is enabled on a best effort basis, but if this operation does not succeed, setClusterMode_Task must be called to enable it. State replication or failover is not allowed until the VCHA Cluster is enabled. The current vCenter Server continues to serve client requests during and after the configuration.

Required Privileges: Global.VCServer

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.
configSpec	VchaClusterConfigSpec	contains the configuration for the cluster

Return Value

Type	Description
ManagedObjectReference to a Task	This method returns a Task object with which to monitor the progress of the operation.

Faults

Type	Description
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Events

Type
None

createPassiveNode_Task

Creates a Passive node in a degraded VCHA Cluster with node location information and pre-existing VCHA Cluster configuration from the Active node.

Required Privileges: Global.VCServer

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.
passiveDeploymentSpec	PassiveNodeDeploymentSpec	contains deployment specification for the passive node
sourceVcSpec	SourceNodeSpec	contains specification for the source vCenter server that is used to create Passive node

Return Value

Type	Description
ManagedObjectReference to a Task	This method returns a Task object with which to monitor the progress of the operation.

Faults

Type	Description
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Events

Type
None

createWitnessNode_Task

Creates a Witness node in a degraded VCHA Cluster with node location information and pre-existing VCHA Cluster configuration from the Active node.

Required Privileges: Global.VCServer

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.
witnessDeploymentSpec	NodeDeploymentSpec	contains deployment specification for the witness node
sourceVcSpec	SourceNodeSpec	contains specification for the source vCenter server that is used to create Witness node

Return Value

Type	Description
ManagedObjectReference to a Task	This method returns a Task object with which to monitor the progress of the operation.

Faults

Type	Description
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Events

Type
None

deployVcha_Task(deploy)

Deploys and Configures VCHA on the local vCenter as a single API. This deployment operation automatically provisions and creates a Passive and a Witness node followed by configuring each node such that a 3 node VCHA Cluster is formed. After configuration, the VCHA Cluster is enabled on a best effort basis, but if this operation does not succeed, setClusterMode_Task must be called to enable it. State replication or failover is not allowed until the VCHA Cluster is enabled. The current vCenter Server continues to serve client requests during and after the deployment. If the activeVcNetworkConfig spec if filled in, the cluster network will be created and configured. No changes will be made if the cluster network is already configured.

Required Privileges: Global.VCServer

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.
deploymentSpec	VchaClusterDeploymentSpec	contains the information needed to deploy and configure a VCHA Cluster

Return Value

Type	Description
ManagedObjectReference to a Task	This method returns a Task object with which to monitor the progress of the operation.

Faults

Type	Description
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Events

Type
None

destroyVcha_Task(destroy)

Destroys the VCHA cluster setup and removes all VCHA specific configuration from the VCVA appliance. The active node in the cluster continues to run as a standalone VCVA appliance after the destroy operation has been performed. This operation is allowed under the following circumstances: - VCHA cluster is disabled - The node is in an isolated state - VCHA Deploy/Configure has failed

Required Privileges: Global.VCServer

Parameters

Name	Type	Description
_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.

Type	Description
RuntimeFault	Thrown if any type of runtime fault is thrown that is not covered by the other faults; for example, a communication error.

Events

Type
None

getVchaConfig(getConfig)

Returns the configuration information for each node that is part of the VCHA Cluster.

Required Privileges: System.Read

_this	ManagedObjectReference	A reference to the FailoverClusterConfigurator used to make the method call.

Return Value

Type	Description
VchaClusterConfigInfo	Returns a data structure specifying configuration for Active, Passive and Witness node in the Cluster.

prepareVcha_Task(prepare)

Prepares the vCenter appliance for a VCHA cluster deployment. This preparation operation saves the network configuration of the cluster and configures the Active node to be cloned for a VCHA configuration. Prepares the VCHA Active node for ssh keys, vpostgres replication and related configuration file setup needed for a VCHA cluster. If the Active node Cluster network adapter does not exist the prepare operation will fail. No changes will be made if the cluster is already configured.
