It takes ResourceGroup or array of VMs are arguments. You can exclude list of VMs from the RG using vmsExcludedFromAction parameter. .PARAMETER Action Specifies the action (Start or Stop) to perform on VM(s). .PARAMETER ResourceGroupName Specifies the name of ResourceGroup. "RG1" or "RG1,RG2,RGn". .PARAMETER VMList Specifies the name of virtual machine(s). "VM1" or "VM1,VM2,VMn". .PARAMETER vmsExcludedFromAction Specifies the name of virtual machine(s) that you want to SKIP from action. "VM1" or "VM1,VM2,VMn". .PARAMETER Simulate Use this switch parameter to perform WhatIf action. .INPUTS None. You cannot pipe objects to command. .OUTPUTS System.String. command returns a string with the status of action performed on workload. .EXAMPLE PS> StartStop-VirtualMachine -Action Stop -ResourceGroupName mytestrg1984 -Simulate # Command simulate the action on the RG mytestrg1984 for all VMs. *** Running in SIMULATE mode.
