Testing Active/Passive Datapower Cluster
Testing an Active/Passive Datapower Cluster is very easy. Just create exactly the same XML Firewall service on both Datapower A and Datapower B appliances. Specify the front End-Handler IP address as the VIP address created.
Execute the curl command to run the policy where the VIP is the Front Side Handler. Enable the probes on both devices to make sure that the request and response is successful. Switch the active appliance (Datapower A) off or reboot and continue to execute the command. You will see that the passive appliance will take over from Datapower A. When Datapower A is rebooted or switched on again it will take over again.
