## Managed Object Description

The ClusterComputeResource data object aggregates the compute resources of associated HostSystem objects into a single compute resource for use by virtual machines. The cluster services such as HA (High Availability), DRS (Distributed Resource Scheduling), and EVC (Enhanced vMotion Compatibility), enhance the utility of this single compute resource.

Use the Folder.CreateClusterEx method to create an instance of this object.

# AbandonHciWorkflow

Opt out of the HCI workflow. This operation is only allowed on a cluster that was created with the HCI workflow. When the cluster is created, but still unconfigured, the workflowState is "in_progress". The AbandonHciWorkflow method may be called at any time before cluster configuration begins; it is not possible to abandon the workflow during the configuration procedure.

# AddHost_Task(addHost)

Adds a host to the cluster. The hostname must be either an IP address, such as 192.168.0.1, or a DNS resolvable name. DNS names may be fully qualified names, such as host1.domain1.com, or a short name such as host1, providing host1 resolves to host1.domain1.com. The system uses DNS to resolve short names to fully qualified names. If the cluster supports nested resource pools and the user specifies the optional ResourcePool argument, then the host's root resource pool becomes the specified resource pool. The stand-alone host resource hierarchy is imported into the new nested resource pool.

If the cluster does not support nested resource pools, then the stand-alone host resource hierarchy is discarded and all virtual machines on the host are put under the cluster's root resource pool.

In addition to the Host.Inventory.AddHostToCluster and Resource.AssignVMToPool privileges, it requires System.View privilege on the VM folder that the VMs of the host will be placed on.

# ClusterEnterMaintenanceMode(enterMaintenanceMode)

The API takes a list of hosts in the cluster as input, and returns a list of hosts in "ClusterMaintenanceResult" that the server can successfully evacuate given the existing constraints in the cluster, such as HA, FT, Vmotion compatibility, reservations, affinity rules, etc. The client is allowed to pass all hosts in the cluster to the API, even though all of them cannot enter maintenance mode at the same time. The list returned from the API contains the largest number of hosts that the server can evacuate simultaneously. The client can then request to enter each host in the returned list into maintenance mode. The client can specify an integer "DemandCapacityRatioTarget" option in the "option" parameter. The allowed values of the option range from 40 to 200, and the default value is 100. This option controls how much resource overcommitment the server should make in consolidating the VMs onto fewer hosts. A value of 100 means the server will keep the same amount of powered-on capacity as the current VM demands. A value less than 100 means undercommitted resources. A value greater than 100 means overcommitted resources. The hosts are recommended based on the inventory at the time of the API invocation. It is not guaranteed that the actual enter-maintenance tasks on the hosts will succeed, if the inventory changes after the API returns, or if vmotions fail due to unexpected conditions. For possible exceptions thrown by the necessary relocate operations, see MigrateVM_Task.

# MoveHostInto_Task(moveHostInto)

Moves an existing host into a cluster. The host must be part of the same datacenter, and if the host is part of a cluster, the host must be in maintenance mode.

If the host is a stand-alone host, the stand-alone ComputeResource is removed as part of this operation.

All virtual machines associated with the host, regardless of whether or not they are running, are moved with the host into the cluster. If there are virtual machines that should not be moved, then migrate those virtual machines off the host before initiating this operation.

If the host is a stand-alone host, the cluster supports nested resource pools, and the user specifies the optional resourcePool argument, then the stand-alone host's root resource pool becomes the specified resource pool and the stand-alone host resource hierarchy is imported into the new nested resource pool. If the cluster does not support nested resource pools or the resourcePool argument is not specified, then the stand-alone host resource hierarchy is ignored.

# MoveInto_Task(moveInto)

Moves an existing host into a cluster. The host must be part of the same datacenter, and if the host is part of a cluster, the host must be in maintenance mode.

If the host is part of a stand-alone ComputeResource, then the stand-alone ComputeResource is removed as part of this operation.

All virtual machines associated with a host, regardless of whether or not they are running, are moved with the host into the cluster. If there are virtual machines that should not be moved, then migrate those virtual machines off the host before initiating this operation.

For stand-alone hosts, the host resource pool hierarchy is discarded in this call. To preserve a host resource pools from a stand-alone host, call moveHostInt, specifying an optional resource pool. This operation is transactional only with respect to each individual host. Hosts in the set are moved sequentially and are committed, one at a time. If a failure is detected, then the method terminates with an exception. Since hosts are moved one at a time, if this operation fails while in the process of moving multiple hosts, some hosts are left unmoved.

In addition to the privileges mentioned, the user must also hold Host.Inventory.EditCluster on the host's source ComputeResource object.

Required Privileges
  Host.Inventory.EditCluster

# RecommendHostsForVm(recommendHostsForVm)

Deprecated. As of VI API 2.5, use PowerOnMultiVM_Task. RecommendHostsForVm cannot make any recommendations if DRS cannot find the specified host in the cluster. With PowerOnMultiVM_Task, DRS attempts to migrate virtual machines and power on hosts in standby mode, given the same conditions.

Gets a recommendation for where to power on, resume, revert from powered-off state to powered on state, or to migrate a specific virtual machine. If no host is found, an empty list is returned.

The type of operation is implied by the state of the virtual machine. Returned hosts are intended for power-on or resume if the virtual machine is powered-off or suspended. However, if the virtual machine is powered-on, the request is assumed to be for migrating a virtual machine into a DRS enabled cluster. In that case, the ResourcePool argument should be specified and the ResourcePool and the virtual machine cannot be in the same cluster.

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the ClusterComputeResource used to make the method call.
spec P | ClusterConfigSpec | A set of configuration changes to apply to the cluster. The specification can be a complete set of changes or a partial set of changes, applied incrementally. Since 2.0
modify P | xsd:boolean | Flag to specify whether the specification ("spec") should be applied incrementally. If "modify" is false and the operation succeeds, then the configuration of the cluster matches the specification exactly; in this case any unset portions of the specification will result in unset or default portions of the configuration. Since 2.0

# ValidateHCIConfiguration(validateHCIConfiguration)

Validate HCI configuration in pre-configure and post-configure use-cases.

1. pre-configure use-case: Validates the HCI configuration to be applied on the cluster. A successful validation in this case means the HCIConfigSpec can be applied without errors on the cluster using ConfigureHCI_Task or ExtendHCI_Task
   These are the things the API validates:
   1. When providing a set of physical adapters in the dvsProf argument, the API validates that all the adapters should be present on all the hosts to be validated. The adapters should either be unmapped or mapped to the same vSwitch across hosts. In addition to this, if the adapters are connected to a DistributedVirtualSwitch, it should be exactly the same way as specified in the dvsProf or in the dvsSetting.
   2. The API will also validate that the ESXi versions of the hosts are compatible with the version of the DistributedVirtualSwitch being created.
2. post-configure case: Validate the cluster has been configured correctly as per the ClusterComputeResourceHCIConfigInfo for the cluster. In this case, the API should be invoked with both params omitted as the intent is to validate all hosts in the cluster using the existing ClusterComputeResourceHCIConfigInfo
