When it's needed to upgrade your Exinda device to the latest firmware version, the specific procedure needs to be followed. During the upgrade process, the Exinda will reboot with an approx downtime of 15-30 minutes, depending on how busy the device is.
This article provides the steps required for you to perform an upgrade on your Exinda system.
- Access to the Exinda WebUI
- Users should make sure they refer to the release notes to follow the correct upgrade path
- Users should keep a copy of the current config safe for disaster recovery
- Exinda's management port should have access to the internet and has a valid DNS server configured
- Log in to your Exinda WebUI
- Navigate to Configuration > System > Maintenance
- Click on the Firmware Update tab and then click on the Check For Latest Update button
- Click on the Release Notes link, which will take you to the Release Notes article
- In the Release Notes article, right-click on the installer, and click on the Copy link address option
- Go back to the Firmware Update window (step 3), make sure the Install From URL is checked, and paste the image URL you just copied, right next to it
- Read the Exinda End User License Agreement and if you agree, check the Accept checkbox and then click on the Install Image button
- Wait for the installation to complete (you can refer to the progress bar that comes up)
Note: Additionally, you can also download the img and instead of selecting the Install From URL you can select the Install From Local File and then upload the img file.
- Once it has finished installing it, it will come up with a yellow box letting you know that a reboot is required
- Click on that button, and it will take you to the Reboot / Shutdown page
- Make sure the System Watchdog is enabled, and then click on the Reboot button
- The WebUI will show a System Temporarily Unavailable page while is getting rebooted
You can validate the version which is installed on the main menu of the Exinda WebUI
Additional DB Information
When the system is first rebooted, the database portion of the upgrade happens if required (i.e., moving from v6 to v7 or between two versions that have database changes). It can take anywhere from 5 minutes to a handful of hours. During this time, while the database is being upgraded, traffic passes through the Exinda, and the optimizer remains on, but there might be a few moments where historical data is not entirely captured due to the upgrade state. Once the update to the database is done, it immediately starts up again, and the operation continues as intended.
Exinda has two partitions. When upgrading, the new version is done on the other partition and switches a flag that points to which partition to boot to point to the newly installed image. Then you have to reboot, if not the upgrade will not be completed. If you reboot and on the new image when it comes up there are some issues, you can go to the same tab for upgrading. Click on switch partition to boot, so it points to the previous partition, reboot the appliance and it will boot into the previous version.
