This cmdlet modifies the configuration of a cluster. HAEnabled is automatically set to $true if some of the HA settings, HAAdmissionControlEnabled, HAFailoverLevel, HARestartPriority, or HAIsolationResponse are specified. DrsEnabled is automatically set to $true if some of the DRS settings, DrsAutomationLevel, or DrsMode are specified.
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| Cluster | Cluster[] | named |
| Specifies the name of the cluster you want to configure. | |
| optional | Name | String | 1 | Specifies a new name for the cluster. | |
| optional | BaseImage | BaseImage | named | Specifies the ESXi base image that the cluster’s hosts should comply with. | |
| optional | Component | Component[] | named | Specifies the ESXi components that the cluster’s hosts should comply with. | |
| optional | CryptoMode | CryptoMode | named | Specifies the cluster encryption mode you want to configure. When set to OnDemand, hosts in the cluster are not required to be in a cryptographically “Safe” state. When set to ForceEnable, all hosts in the cluster are forced to be cryptographically “Safe”, that is, vCenter Server has installed a host key on the host. | |
| optional | DepotOverride | String[] | named | Specifies a depot address from where the cluster can fetch metadata and resources for the vSphere Lifecycle Manager operations. | |
| optional | DrsAutomationLevel | DrsAutomationLevel | named | Specifies a DRS automation level. The valid values are FullyAutomated, Manual, and PartiallyAutomated. | |
| optional | DrsEnabled | Boolean | named | If specified, enables VMware DRS. | |
| optional | DrsMode | DrsMode | named | This parameter is deprecated and scheduled for removal. Use the DrsAutomationLevel parameter instead. Specifies a DRS mode. The valid values are FullyAutomated, Manual, and PartiallyAutomated. | |
| optional | EVCMode | String | named | Specifies the EVC mode of the newly created cluster. If not specified or set to $null, EVC is deactivated. | |
| optional | FirmwareAddon | Package | named | Specifies a package from a hardware support manager that the hosts on a cluster should comply with. This parameter has been renamed from “Package”. A PowerShell alias “Package” for this parameter has been added for backward compatibility of PowerShell scripts. | |
| optional | HAAdmissionControlEnabled | Boolean | named | Indicates that the virtual machines in the cluster will not start if they violate availability constraints. | |
| optional | HAEnabled | Boolean | named | If specified, enables VMware High Availability. | |
| optional | HAFailoverLevel | Int32 | named | Specifies a failover level. This is the number of physical host failures that can be tolerated without impacting the ability to meet minimum thresholds for all running virtual machines. The valid values are in the range of 1 to 4. | |
| optional | HAIsolationResponse | HAIsolationResponse | named | Specifies whether the virtual machine should be powered off if a host determines that it is isolated from the rest of the compute resource. The valid values are PowerOff and DoNothing. Passing values to this parameter through a pipeline is deprecated and will be deactivated in a future release. | |
| optional | HARestartPriority | HARestartPriority | named | Specifies the cluster HA restart priority. The valid values are Disabled, Lowest, Low, Medium, High, and Highest. VMware HA is a feature that detects failed virtual machines and automatically restarts them on alternative ESX/ESXi hosts. Passing values to this parameter through a pipeline is deprecated and will be deactivated in a future release. | |
| optional | Profile | VMHostProfile | named |
| Specifies a host profile you want to associate with the cluster. If the value of this parameter is $null, the current profile association is removed. |
| optional | RunAsync | SwitchParameter | named | Indicates that the command returns immediately without waiting for the task to complete. In this mode, the output of the cmdlet is a Task object. For more information about the RunAsync parameter run “help About_RunAsync” in the VMware PowerCLI console. | |
| optional | Server | VIServer[] | named |
| Specifies the vCenter Server systems on which you want to run the cmdlet. If no value is provided or $null value is passed to this parameter, the command runs on the default servers. For more information about default servers, see the description of the Connect-VIServer cmdlet. |
| optional | VMSwapfilePolicy | VMSwapfilePolicy | named | Specifies the swapfile placement policy. The following values are valid: InHostDataStore – stores the swapfile in the datastore specified by the VMSwapfileDatastoreID property of the virtual machine host. If the VMSwapfileDatastoreID property is not set or indicates a datastore with insufficient free space, the swapfile is stored in the same directory as the virtual machine. This setting might degrade the vMotion performance. WithVM – stores the swapfile in the same directory as the virtual machine. | |
| optional | VendorAddOn | AddOn | named | Specifies the ESXi vendor add-on that the cluster’s hosts should comply with. | |
| optional | VsanDiskClaimMode | VsanDiskClaimMode | named | Specifies the mode by which disks are claimed by vSAN. | |
| optional | VsanEnabled | Boolean | named | Specifies whether the vSAN feature is enabled on this cluster. | |
| optional | VsanEsaEnabled | Boolean | named | Indicates that the vSAN ESA feature is enabled on this cluster. This feature is supported from vSphere 8.0. |
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| Cluster | Cluster[] | named |
| Specifies the name of the cluster you want to configure. | |
| Remediate | SwitchParameter | named | Indicates that you want to remediate the cluster’s hosts to the target state. | ||
| optional | AcceptEULA | SwitchParameter | named | Indicates that the End User License Agreement (EULA) is accepted for the images that you want to install on the cluster’s hosts in order to comply with the target state. | |
| optional | RunAsync | SwitchParameter | named | Indicates that the command returns immediately without waiting for the task to complete. In this mode, the output of the cmdlet is a Task object. For more information about the RunAsync parameter run “help About_RunAsync” in the VMware PowerCLI console. | |
| optional | Server | VIServer[] | named |
| Specifies the vCenter Server systems on which you want to run the cmdlet. If no value is provided or $null value is passed to this parameter, the command runs on the default servers. For more information about default servers, see the description of the Connect-VIServer cmdlet. |
