Managing Gateway Updates Using the AWS
Storage Gateway Console
AWS Storage Gateway periodically releases important software updates for your gateway. Either you
can manually apply updates on the AWS Storage Gateway Management Console, or the updates are
automatically applied during the configured maintenance schedule. Although Storage Gateway checks
for updates every week or every month, it only goes through maintenance and restart if there are
updates.
Before any update is applied to your gateway, AWS notifies you with a message on the Storage Gateway
console and your AWS Personal Health Dashboard. For more information, see AWS Personal Health
Dashboard. The VM doesn't reboot, but the gateway is unavailable for a short period while it's being
updated and restarted.
When you deploy and activate your gateway, a default weekly maintenance schedule is set. You can
modify the maintenance schedule at any time. When updates are available, the Details tab displays a
maintenance message. You can see the date and time that the last successful update was applied to your
gateway on the Details tab.
Important
You can minimize the chance of any disruption to your applications due to the gateway
restart by increasing the timeouts of your iSCSI initiator. For more information about
increasing iSCSI initiator timeouts for Windows and Linux, see Customizing Your Windows iSCSI
Settings (p. 374) and Customizing Your Linux iSCSI Settings (p. 376).
To modify the maintenance schedule
1. Open the AWS Storage Gateway console at https://console.amazonaws.cn/storagegateway/home.
2. On the navigation pane, choose Gateways, and choose the gateway that you want to modify the
update schedule for.
3. On the Actions menu, choose Edit maintenance window.
