Managing Gateway Updates Using the AWS Storage Gateway Console

AWS Storage Gateway periodically deploys important updates and patches to your gateway that must be applied. Amazon will notify you via the AWS Storage Gateway console and via email in advance of any updates to your gateway. Software updates force a restart of your gateway which typically takes a few minutes to complete. You do not have to take any action, and in particular, you should not restart the VM manually. After the update, your gateway and its volumes will be in the same states as they were before the update. While the software update is being applied, application reads and writes from initiators to gateway storage volume targets are buffered and when the update is complete, the gateway processes them. 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 Customizing Your Windows iSCSI Settings and Customizing Your Linux iSCSI Settings, respectively.

You can choose to let AWS Storage Gateway apply updates according to the maintenance schedule for your gateway or you can apply the update yourself. When you deploy and activate your gateway, a default weekly maintenance schedule is set. You can modify this schedule at any time by clicking edit next to Maintenance Start Time in the Gateway tab. The following example shows the gateway maintenance tab with a maintenance message and the button in the UI for applying the update.
