## Managed Object Description

The HostSystem managed object type provides access to a virtualization host platform.

Invoking destroy on a HostSystem of standalone type throws a NotSupported fault. A standalone HostSystem can be destroyed only by invoking destroy on its parent ComputeResource. Invoking destroy on a failover host throws a DisallowedOperationOnFailoverHost fault. See ClusterFailoverHostAdmissionControlPolicy.

# ConfigureCryptoKey(configureCryptoKey)

Sets/changes the key to be used for coredump encryption and puts the host in vim.HostSystem.CryptoState#safe state. This function will make the host crypto safe and unlock all encrypted VMs on the host. When the encryption on the host is enabled for the first time after adding it to vCenter Server, this method will start sending asynchronously all the encryption keys for VMs on the host and cluster to unlock encrypted VMs. This API behaves differently on the ESXi host vs. the vCenter server. Before vSphere 7.0, it is not supported on host, and invoking directly on a host will throw NotSupported fault. Since vSphere 7.0, calling the API on host will make the host crypto safe, but the parameter should not be blank and should only be a key id from a trusted key provider.

# EnterLockdownMode(enterLockdownMode)

Deprecated. As of vSphere API 6.0, use ChangeLockdownMode.

Modifies the permissions on the host, so that it will only be accessible through local console or an authorized centralized management application. Any user defined permissions found on the host are lost.

Access via a VI client connected to the host is blocked. Access though other services running on the host is also blocked.

If the operation is successful, adminDisabled will be set to true. This API is not supported on the host, If invoked directly on a host, a NotSupported fault will be thrown.

# EnterMaintenanceMode_Task(enterMaintenanceMode)

Puts the host in maintenance mode. While this task is running and when the host is in maintenance mode, no virtual machines can be powered on and no provisioning operations can be performed on the host. Once the call completes, it is safe to turn off a host without disrupting any virtual machines.

The task completes once there are no powered-on virtual machines on the host and no provisioning operations in progress on the host. The operation does not directly initiate any operations to evacuate or power-down powered-on virtual machines. However, if the host is part of a cluster with VMware DRS enabled, DRS provides migration recommendations to evacuate the powered-on virtual machines. If DRS is in fully-automatic mode, these are automatically scheduled.

If the host is part of a cluster and the task is issued through VirtualCenter with evacuatePoweredOffVms set to true, the task will not succeed unless all the powered-off virtual machines are reregistered to other hosts. If VMware DRS is enabled, vCenter Server will automatically evacuate powered-off virtual machines.

If this API is called directly on the ESXi host, then the user is responsible for powering off, suspending or evacuating all powered-on virtual machines. The task is cancellable.

Required Privileges
  Host.Config.Maintenance

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the HostSystem used to make the method call.
timeout P | xsd:int | The task completes when the host successfully enters maintenance mode or the timeout expires, and in the latter case the task contains a Timeout fault. If the timeout is less than or equal to zero, there is no timeout. The timeout is specified in seconds. Since 2.0
evacuatePoweredOffVms* P | xsd:boolean | This is a parameter only supported by VirtualCenter. If set to true, for a DRS disabled cluster, the task will not succeed unless all powered-off virtual machines have been manually reregistered; for a DRS enabled cluster, VirtualCenter will automatically reregister powered-off virtual machines and a powered-off virtual machine may remain at the host only for two reasons: (a) no compatible host found for reregistration, (b) DRS is disabled for the virtual machine. If set to false, powered-off virtual machines do not need to be moved. Since 2.0
maintenanceSpec* P | HostMaintenanceSpec | Any additional actions to be taken by the host upon entering maintenance mode. If omitted, default actions will be taken as documented in the HostMaintenanceSpec. Since 2.0

*Need not be set P Required privilege - see tooltip for details

# ExitLockdownMode(exitLockdownMode)

Deprecated. As of vSphere API 6.0, use ChangeLockdownMode.

Restores Administrator permission for the local administrative account for the host that was removed by prior call to EnterLockdownMode. If the operation is successful, adminDisabled will be set to false. This API is not supported on the host. If invoked directly on a host, a NotSupported fault will be thrown.

# PowerDownHostToStandBy_Task(enterStandbyMode)

Puts the host in standby mode, a mode in which the host is in a standby state from which it can be powered up remotely. While this task is running, no virtual machines can be powered on and no provisioning operations can be performed on the host.

The task completes only if there are no powered-on virtual machines on the host, no provisioning operations in progress on the host, and the host stopped responding. The operation does not directly initiate any operations to evacuate or power-down powered-on virtual machines. However, if a dynamic recommendation generation module is running, if possible, it will provide, and depending on the automation level, it will execute migrations of powered-on virtual machine. Furthermore, VMware power management module may evacute and put a host in standby mode to save power. If the host is part of a cluster and the task is issued through VirtualCenter with evacuatePoweredOffVms set to true, the task will not succeed unless all the powered-off virtual machines are reregistered to other hosts. If VMware DRS is enabled, vCenter Server will automatically evacuate powered-off virtual machines.

The task is cancellable.

This command is not supported on all hosts. Check the host capability standbySupported.

# PowerUpHostFromStandBy_Task(exitStandbyMode)

Takes the host out of standby mode. If the command is successful, the host wakes up and starts sending heartbeats. This method may be called automatically by a dynamic recommendation generation module to add capacity to a cluster, if the host is not in maintenance mode.

Note that, depending on the implementation of the wakeup method, the client may never receive an indicator of success in the returned task. In some cases, it is not even possible to ensure that the wakeup request has made it to the host.

# RebootHost_Task(reboot)

Reboots a host. If the command is successful, then the host has been rebooted. If connected directly to the host, the client never receives an indicator of success in the returned task but simply loses connection to the host, upon success.

This command is not supported on all hosts. Check the host capability rebootSupported. If QuickBoot is enabled on the host, additional setup steps are performed.

Required Privileges
  Host.Config.Maintenance

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the HostSystem used to make the method call.
force P | xsd:boolean | Flag to specify whether or not the host should be rebooted regardless of whether it is in maintenance mode. If true, the host is rebooted, even if there are virtual machines running or other operations in progress. Since 2.0

# ReconfigureHostForDAS_Task(reconfigureDAS)

Reconfigures the host for vSphere HA.

If the host is part of a HA cluster, this operation reconfigures the host for HA. For example, this operation may be used if a host is added to a HA enabled cluster and the automatic HA configuration system task fails. Automatic HA configuration may fail for a variety of reasons. For example, the host is configured incorrectly.

Required Privileges

# ReconnectHost_Task(reconnect)

Reconnects to a host. This process reinstalls agents and reconfigures the host, if it has gotten out of date with VirtualCenter. The reconnection process goes through many of the same steps as addHost: ensuring the correct set of licenses for the number of CPUs on the host, ensuring the correct set of agents is installed, and ensuring that networks and datastores are discovered and registered with VirtualCenter.

The client can change the IP address and port of the host when doing a reconnect operation. This can be useful if the client wants to preserve existing metadata, even though the host is changing its IP address. For example, clients could preserve existing statistics, alarms, and privileges.

This method can also be used to change the SSL thumbprint of a connected host without disconnecting it.

Any changes made to the resource hierarchy on the host when the host was disconnected are overriden by VirtualCenter settings on reconnect.

This method is only supported through VirtualCenter.

Required Privileges
  Host.Config.Connection

Parameters

Name | Type | Description
--- | --- | ---
_this | ManagedObjectReference | A reference to the HostSystem used to make the method call.
cnxSpec* P | HostConnectSpec | Includes the parameters to use, including user name and password, when reconnecting to the host. If this parameter is not specified, the default connection parameters is used. Since 2.0
reconnectSpec* P | HostSystemReconnectSpec | Includes connection parameters specific to reconnect. This will mainly be used to indicate how to handle divergence between the host settings and vCenter Server settings when the host was disconnected. Since 2.0

*Need not be set P Required privilege - see tooltip for details

Return Value

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

Faults
