Virtual Machine Scale Sets - Power Off

Service:

Compute

API Version:

2024-07-01

Power off (stop) one or more virtual machines in a VM scale set. Note that resources are still attached and you are getting charged for the resources. Instead, use deallocate to release resources and avoid charges. Additionally, this operation is not allowed on virtual machines in a VM scale set that are being deallocated or have already been deallocated.

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/poweroff?api-version=2024-07-01

With optional parameters:

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/poweroff?skipShutdown={skipShutdown}&api-version=2024-07-01

URI Parameters

Name	In	Required	Type	Description
resourceGroupName	path	True	string	The name of the resource group.
subscriptionId	path	True	string	Subscription credentials which uniquely identify Microsoft Azure subscription. The subscription ID forms part of the URI for every service call.
vmScaleSetName	path	True	string	The name of the VM scale set.
api-version	query	True	string	Client Api Version.
skipShutdown	query		boolean	The parameter to request non-graceful VM shutdown. True value for this flag indicates non-graceful shutdown whereas false indicates otherwise. Default value for this flag is false if not specified

Request Body

Name	Type	Description
instanceIds	string[]	The virtual machine scale set instance ids. Omitting the virtual machine scale set instance ids will result in the operation being performed on all virtual machines in the virtual machine scale set.

Responses

Name	Type	Description
200 OK		OK
202 Accepted		Accepted
Other Status Codes	CloudError	Error response describing why the operation failed.
