-- | This operation updates the gateway virtual machine (VM) software. The request
-- immediately triggers the software update.
--
-- 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.
