Set-VMHost Command | Vmware PowerCLI Reference

Set-VMHost

This cmdlet modifies the configuration of the host.The State parameter is set to Connected. - If the host is currently connected and is not in a maintenance mode, it does nothing.- If the host is in a maintenance mode, it exits the maintenance mode.- If the host is not connected or is not responding, it tries to reconnect.The State parameter is set to Disconnected. - If the host is currently connected, it attempts to disconnect.- If the host is not connected or not responding, it does nothing.The State parameter is set to Maintenance. - If the host is currently connected and not in a maintenance mode, it enters a maintenance mode.- If the host is currently connected and in a maintenance mode, it does nothing.- If the host is not connected or not responding, it attempts to reconnect and enter maintenance mode.The KeyProvider parameter is provided: - If the host is not in a cryptographically "Safe" state, the cmdlet makes the host cryptographically "Safe".- If the host is already in a cryptographically "Safe" state, the cmdlet resets the host key in the host.

Parameters

Required Parameter Name Type Position Features Description
required
 VMHost VMHost[] 1
  • pipeline
  • wildcards
 Specifies the host you want to configure.
optional BaseImage BaseImage named
Specifies the ESXi base image that the host should comply with.
optional Component Component[] named
Specifies the ESXi component(s) that the host should comply with.
optional DepotOverride String[] named
Specifies a depot address from where the host can fetch metadata and resources for the vSphere Lifecycle Manager operations.
optional Evacuate 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 FirmwareAddon Package named
Specifies a package from a hardware support manager that the host should comply with.
optional LicenseKey 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 Profile VMHostProfile named
  • wildcards
 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 Reason String named
Specifies a short message containing the reason for putting the host in maintenance mode. The message cannot be null or empty string. This parameter can only be used when passing "Maintenance" value to the "State" parameter.
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
  • wildcards
 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 State 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 TimeZone VMHostTimeZone named
  • wildcards
 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 VMSwapfileDatastore Datastore named
  • wildcards
 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 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 host should comply with.
optional VsanDataMigrationMode 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
 DisableCryptoSafe 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 deactivated 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.
