You can create, attach, detach, and reattach [data disks](/azure/virtual-machines/managed-disks-overview) for lab VMs that you own. This functionality is handy for managing storage or software separately from individual VMs.

 ## Azure PowerShell script
 
 The following PowerShell script starts or stops a VM in a lab by using [Invoke-AzResourceAction](/powershell/module/az.resources/invoke-azresourceaction). The `ResourceId` parameter is the fully qualified ID for the lab VM you want to start or stop. The `Action` parameter determines whether to start or stop the VM, depending on which action you need.
