AWS Elemental MediaConnect routinely performs maintenance on underlying systems for security, reliability, and operational performance. The maintenance activities include actions such as patching the operating system, updating drivers, or installing software and patches.
Note
As part of the maintenance process, your flow must be restarted.
You can select the day and time that maintenance events occur. This is called a maintenance window and is used every time a maintenance event is required. If you need to change the day and time, you can edit the maintenance window.
When maintenance is required for your flow, AWS will assign your flow a Required by date. If you do not have a maintenance window configured for the flow, visit Setting maintenance windows. You can view the flows that require maintenance on the MediaConnect console or by using the AWS CLI, visit Viewing flows that require maintenance. When a Required by date has been assigned to your flow, you can select a specific date for that maintenance to occur. The selected Maintenance date will only apply to the next maintenance event.
If you do not configure a maintenance window, AWS selects a maintenance window for you—automatically. We recommend that you set a maintenance window for each flow and allow MediaConnect to perform the restart automatically during that window. Allowing MediaConnect to perform the restart results in less downtime for your flow. If a flow requires maintenance and you choose to manually restart the flow, the status of that flow's maintenance will change to Canceled. The manually restarted flow will still apply the required updates, but you will not receive the Completed successfully status. Since you performed the restart manually, the maintenance is considered Canceled because MediaConnect no longer requires updates for that flow.
The duration of the maintenance window is two hours.
Important
The two hour window duration does not mean the flow will be affected for two hours. The flow will perform a normal stop and start at some point within the two hour window.
Example: If you configure a flow's maintenance window Start hour to be 02:00, the flow will restart at some point between 02:00 and 04:00.
In the event that maintenance does not occur at the scheduled date and time, MediaConnect will reschedule it to occur in the following week’s maintenance window, or automatically set a new window if you don't have one configured.
