Backup and Redundancy

Replacing an Application Server in a Redundancy Group

616

When the current IP is unknown and the operation state is Offline, operators may choose to
replace the Application Server. The Replace function switches the online, Main Application
Server with another Application Server outside the Redundancy Group.

To replace an Application Server in a Redundancy Group

1. On the Redundancy Configuration Form, in the Main area, identify the row associated

with the Application Server you would like to replace.

Figure 10-42

2. You may select or clear the Take over the main IP address after failover check box as

required.

REQUIREMENTS

Make sure you meet the following conditions before beginning this procedure:

• An Auto-failover or Manual Takeover has occurred and the Replace button is visible in

the Redundancy Configuration Form for the server you would like to replace.

• You have opened iControl for the Backup Application Server (see

page 696

).

• You have navigated to the Redundancy Configuration Form for the Application Server

mentioned in the requirement before this one (see

• Cabling for eth0 and eth1 interfaces on the replacing Application Server is properly
