The Aviatrix PaaS console provides the ability to create a maintenance window that allows you to determine when updates to Aviatrix gateways should occur. You can modify the maintenance window options from the Maintenance card in Settings.

​
Maintenance Window Overview

Maintenance updates are required and are scheduled on a regular basis for Aviatrix updates. Any available update not completed within a week might be forced. When selecting the schedule for a maintenance window, the day and time are configured according to the time zone set in your user preferences. The default is the time zone of your browser.
Urgent unscheduled updates might occasionally be required, such as addressing CVEs. In these circumstances, Aviatrix might need to perform updates outside the scheduled maintenance window.
Approximately 10 minutes before the start of a maintenance, information displays in the Upcoming Maintenance field on the Maintenance card, letting users know a maintenance is about to begin.
Aviatrix PaaS is not available while maintenance is being performed, so users will not be able to access the Aviatrix PaaS console during maintenance.
A minimum of 4 hours each week should be scheduled for the length of a maintenance window. A maintenance event can begin at any time after the selected time and within the maintenance window length. However, the Aviatrix PaaS console is not available only during the actual time it takes for the update to complete. If a maintenance is not finished within the scheduled window, the update will continue until it completes.

​
Example

Assume the following settings for a maintenance window: Fridays at 4:00 AM for a length of 4 hours. Given those settings, a maintenance update can occur according to the following schedule:
  • A maintenance can be performed on Friday of each week.
  • The selected start time is 4:00 AM, with a window length of 4 hours.
  • Maintenance can start at or after 4:00 AM and any time up to 8:00 AM.
  • A maintenance will not start after 8:00 AM, which is the end of the 4-hour window.
  • When a maintenance event starts, it will continue until it completes. Best effort will be made to complete the maintenance before the end of the window. maintenance window dialog

Configure a Maintenance Window

You can set the date, time, and length of the maintenance window for updates to Aviatrix PaaS. This allows you to choose days and times that are convenient, such as off-peak hours for your business. For more information about maintenance windows for updates, see Maintenance Window Overview. To configure a maintenance window, do the following:
  1. Go to Settings > Maintenance and click Manage. Note that an uneditable default cycle of once every week is set for the maintenance window.
  2. Select one or more days of the week when you prefer updates to occur.
  3. Select the time for updates to occur.
    You can type the time in the field, or click the clock icon for a drop-down list.
  4. Enter a length of time within which an update should be performed. The maintenance window must be at least 4 hours.
  5. Click Save.
A banner displays in the console 15 minutes before a maintenance begins.
