Powershell cmdlet 可正常关闭 azure 虚拟机

Question

I am having questions around the "Stop-AzureRmVm" PowerShell cmdlet. Does the cmdlet power crash the virtual machines? I have few SharePoint and SQL servers used in our non-production environment. I have powershell scripts that do a scheduled stop and start of these virtual machines.

I am worried if the "Stop-AzureRmVm" PowerShell cmdlet power crashes the virtual machines, as I need the servers to gracefully shutdown.

OR do we have any PowerShell cmdlet that gracefully shuts down the Azure virtual machine?

Answer 1

As long as you are not sending the -force parameter, Azure will attempt to gracefully shutdown the guest OS before stopping. If that doesn't work, the -force parameter is akin to "pulling the plug".

Answer 2

Dont worry, the command Stop-AzureRmVm will gracefully shut down the VM.

If you catch the request of the Stop-AzureRmVm and the Stop option of the VM in the portal, you will find essentially they all call the Virtual Machines - Deallocate REST API, it means if you use the powershell command, it is no difference with that in the portal.

Answer 3

Sorry to revive an old question, but Ken W's accepted answer here is not accurate. The -Force parameter only prevents a Yes/No prompt when running the cmdlet (this is useful for when running in an automated script which cannot accept user input). Either way, running Stop-AzureRmVm will always attempt a graceful shutdown.

The newer 'Az' version of this cmdlet (Stop-AzVM) does have a -SkipShutdown option which will skip any attempt at a graceful shutdown, and will immediately deallocate the VM. More details can be found in the following link:
