Service:

Compute

API Version:

2022-08-01

Restarts one or more virtual machines in a VM scale set.

HTTP

POST https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/restart?api-version=2022-08-01

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.

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.
