Stopping iControl Services on the Intended Backup Application Server
To stop iControl services on the intended Backup Application Server
1. On the iControl Webmin page of the Application Server you intend to configure as Backup,
click Miranda iControl Management Tool.
IMPORTANT: System behavior
Immediately following a Manual Takeover or an Auto-failover event, there is
no longer any redundancy as the configured Backup is currently in the active
role of a Main Application Server. In order to restore your system to full
redundancy, you must do one of the following:
•
[Recommended option]: Fix any issues with the configured Main
Application Server that failed over or upon which you performed a
Manual Takeover. Then perform a Reverse Takeover to revert Application
Servers to their configured roles.
•
Fix any issues with the configured Main. Then reconfigure this Application
Server in the role of Backup and the configured Backup in the role of Main.
•
Replace the defective Application Server. Then perform a Replace
Takeover to revert the Backup Application Server to its Backup role and to
use the Application Server to take over the role of the defective Main
Application Server.

• You have opened iControl on the Application Server you intend to configure in the role
