Putting a JBoss ON server in maintenance mode temporarily removes it from the high availability cloud so it no longer processes agent operations. This is useful when the server is offline for upgrades or because of a service interruption.
Procedure 5.2. Set Maintenance Mode on a Server
Click the Administration tab in the top menu.
Click the row to select the JBoss ON server to put into maintenance mode.
Click the Set Maintenance button.
The JBoss ON server can be added back to the high availability cloud by clicking SET NORMAL button. Agents migrate back to the server incrementally.
