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.
Click the Administration tab in the top menu.
In the menu table, select the item.
Select the check box next to the name of the JBoss ON server to put into maintenance mode.
Click the button.
The JBoss ON server can be added back to the high availability cloud by clicking
button. Agents migrate back to the server incrementally.
