The operation shuts down the gateway service component running in the storage gateway's virtual machine (VM) and not the VM.
If you want to shut down the VM, it is recommended that you first shut down the gateway component in the VM to avoid unpredictable conditions.
After the gateway is shutdown, you cannot call any other API except StartGateway, DescribeGatewayInformation, and ListGateways. For more information, see ActivateGateway. Your applications cannot read from or write to the gateway's storage volumes, and there are no snapshots taken.
When you make a shutdown request, you will get a 200 OK
success response immediately. However, it might take some time for the gateway to shut down. You can call the DescribeGatewayInformation API to check the status. For more information, see ActivateGateway.
If do not intend to use the gateway again, you must delete the gateway (using DeleteGateway) to no longer pay software charges associated with the gateway.
