[CommonParameters]
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| required |
|
VMHost[] | 1 |
|
Specifies the host you want to configure. | optional |
|
SwitchParameter | named |
|
If the value is $true, vCenter Server system automatically reregisters the virtual machines that are compatible for reregistration. If they are not compatible, they remain on the host. If there are powered on virtual machines that cannot be reregistered, the operation waits until they are powered off manually. The Evacuate parameter is valid only when connected to a vCenter Server system and the State parameter is set to Maintenance. Also, the virtual machine host must be in a DRS-enabled cluster. | optional |
|
String | named |
|
Specifies the license key to be used by the host. You can set the host to evaluation mode by passing the 00000-00000-00000-00000-00000 evaluation key. | optional |
|
VMHostProfile | named |
|
Specifies a host profile you want to associate with the host. If the value of this parameter is $null, the current profile association is removed. | optional |
|
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 |
|
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 |
|
VMHostState | named |
|
Specifies the state of the host. The valid values are Connected, Disconnected, and Maintenance. If there are powered on virtual machines on the host, you can set the host into a maintenance mode, only if it is a part of a DRS-enabled cluster. Before entering maintenance mode, if the host is fully automated, the cmdlet relocates all powered on virtual machines. If the host is not automated or partially automated, you must first generate a DRS recommendation and wait until all powered on virtual machines are relocated or powered off. In this case, you must specify the RunAsync parameter. Otherwise, an error appears. | optional |
|
VMHostTimeZone | named |
|
Specifies the time zone for the host by using its name or by providing the corresponding time zone object. Time zone names support wildcards. If the wildcards match more than one time zone, an error appears. Time zone objects can only be applied to the hosts they originate from. | optional |
|
Datastore | named |
|
Specifies a datastore that is visible to the host and can be used for storing swapfiles for the virtual machines that run on this host. Using a host-specific swap location might degrade the vMotion performance. | optional |
|
VMSwapfilePolicy | named |
|
Specifies the swapfile placement policy. The following values are valid: | optional |
|
VsanDataMigrationMode | named |
|
Specifies the special action to take regarding the vSAN data when moving in maintenance mode. The VsanDataMigrationMode parameter is valid only when connected to a vCenter Server system and when the State parameter is set to VMHostState.Maintenance. |
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| required |
|
SwitchParameter | named |
|
If the value is $true and the VMHost's previous CryptoState is Safe, the VMHost enters a PendingIncapable state. Otherwise, the VMHost remains in an Incapable state. For the PendingIncapable state, the vmhost is explicitly crypto disabled and pending reboot is to be applied. When vmhost is in this state, creating encrypted virtual machines is not allowed. You need a reboot to totally clean up and enter an Incapable state. | required |
|
VMHost[] | named |
|
Specifies the host you want to configure. | optional |
|
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. |
Parameters
| Required | Parameter Name | Type | Position | Features | Description |
|---|---|---|---|---|---|
| required |
|
KmsCluster | named |
|
Specifies the key provider you want to use to make the VMHost cryptographically "Safe" or rekey the VMHost's host key. | required |
|
VMHost[] | named |
|
Specifies the host you want to configure. | optional |
|
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. |
Output
VMware.VimAutomation.ViCore.Types.V1.Inventory.VMHost
Examples
Example 1
Set-VMHost -VMHost Host -State "Disconnected"
Resets the state of the Host virtual host to Disconnected.
Example 2

$task = Set-VMHost -VMHost Host -State "Maintenance" -RunAsync
Get-DrsRecommendation -Cluster $cluster | where {$_.Reason -eq "Host is entering maintenance mode"} | Apply-DrsRecommendation
$vmhost = Wait-Task $task
Activates a maintenance mode for a not automated host that is part of a DRS-enabled cluster and has powered on virtual machines on it.
Example 3
$keyprovider = Get-KeyProvider | select -First 1
Set-VMHost -VMHost Host -KeyProvider $keyprovider
Resets the cryptokey of the VMHost named 'Host'.
