The Advanced → Redundancy menu contains a single parameter that can be used to add the app server to a Redundancy Group (for app failover). 

This feature is described fully in HOME Apps - Redundancy (App Failover). Here we explain the server's Redundancy Group Tag control.

Redundancy Group Tag 

  • If an existing Redundancy Group Tag is entered, then the App Server is added to the redundancy group specified.
  • If a new Redundancy Group Tag is entered, then this defines a new redundancy group. 
  • If the field is left blank, then the App Server is not part of a redundancy group.

Click on the pencil icon to edit the field. The Reset button can be used to reset to the default value (no redundancy group specified).
