Engaging a Failover of an External Device
498
The system prompts you for the IP address of the Application Server (not currently in the
Redundancy Group) that you would like to assign as a replacement.
4. Click OK once you have typed the IP address.
The following behaviors occur:
• The iControl—Redundancy configuration page refreshes displaying the new
Application Server as the replacement.
• The Backup Application Server will rsync the new Application Server with the
configuration of the Main it is supposed to replace.
• The network setting of the new Application Server will be modified.
• A Reverse Takeover will be initiated.
• The new Application Server will become the online Main.
• The Backup Application Server will go back to standby status.
5. If, in step 2 , you selected the Take over the main IP address after failover check box,
perform the following steps:
a) Change the IP addresses of eth0 and eth1 on the new Application Server to the old
Main’s eth0 and eth1 IP addresses (see "Configuring and Managing Autofailovers of
Application Servers" , on page 495).
b) Restart iControl services on the new Application Server (see "Starting & Stopping
iControl Services" , on page 552).
c) If you are using iC Web, refresh the interface.
Engaging a Failover of an External Device
iControl detects an error on a main device and when Engage Failover is active the router
changes crosspoints for the backup device to feed both the main and the backup outputs.
Engaging Failover
To engage failover
• Select Engage Failover from the Remote Control Monitoring and Pilot Control area
(lower right area of the Web page).
The button becomes grayed out to indicate that it is active.
IMPORTANT: The following failover procedure is applicable only if your iC Web site offers
failover functionality.
