Agent Recovery
Once the Controller is up and running, you can use it to perform recoveries on Agents. For example, if one of your computers crashed that is running Ignition, you can do a fresh install from a previous backup collection that was performed on your Agent. When the recovery is complete, the Agent will immediately pick up where it left off like nothing ever happened.
Backup Required to Perform Agent Recovery
Agent recovery requires that a backup collection was performed, otherwise, you will not be able to use this procedure to recover your Agent’s instance of Ignition.
In this example, let’s assume that the Agent computer crashed. To check the status, go to your Controller, navigate to Enterprise Administration > Agent Management and check the status of the Gateway Agent. You can see that Agent133 is disconnected.
First: on your Agent computer, install Ignition and make sure the EAM Module is also installed (it is not added by default if you use the 'Typical' selection during installation).
On your Agent, go to the Configure tab and select the Enterprise Administration Setup. The EAM wizard will walk you through each step of the Agent recovery process.
Select Agent to configure. Press Next.
In order to continue with the Agent Recovery procedure, you must have a backup collection of the Agent. When you initially setup your Agent on the Controller, you created an Archive Path where the backup files are stored. EAM will automatically know where to retrieve the backup files.
Click on Agent Recovery and press Next.
Since Agent133 existed previously, the EAM remembered the Agent’s prior settings. Choose from the list of names in the dropdown lists for the Controller and Agent.
In this example, select your controller from the dropdown list, and select this Agent from the System Name dropdown list (or you can type it in). Press Finish.
The Agent will go through a series of steps: check the Agent status on the Controller, retrieve the Ignition license file, and download Ignition modules and the latest Gateway backup to the Agent.
When you get a message that this step is complete, press Apply Files.
Once you press the Apply Files button, you will see two consecutive progress bars; one for stopping the Gateway and one for starting. It will take about a minute to bring the Gateway up. The screen will refresh once the Gateway is up and running.
Click on the Configure tab. You will be prompted to log into the Designer.
After logging in, you will see the System Status window. Click on Configure > Projects and you will notice that all your projects are restored.
It's also a good idea to verify that all your modules are activated by going to the Configure tab and selecting Modules.
