-- | This operation updates the gateway virtual machine (VM) software. The request
-- immediately triggers the software update.
--
-- When you make this request, you get a '200 OK' success response immediately.
-- However, it might take some time for the update to complete. You can call 'DescribeGatewayInformation' to verify the gateway is in the 'STATE_RUNNING' state. A software update
-- forces a system restart of your gateway. You can minimize the chance of any
-- disruption to your applications by increasing your iSCSI Initiators'
-- timeouts. For more information about increasing iSCSI Initiator timeouts for
-- Windows and Linux, see <http://docs.aws.amazon.com/storagegateway/latest/userguide/ConfiguringiSCSIClientInitiatorWindowsClient.html#CustomizeWindowsiSCSISettings Customizing Your Windows iSCSI Settings> and <http://docs.aws.amazon.com/storagegateway/latest/userguide/ConfiguringiSCSIClientInitiatorRedHatClient.html#CustomizeLinuxiSCSISettings Customizing Your Linux iSCSI Settings>, respectively.
