Failback
When the issues on the server that host the primary Cisco Prime Infrastructure server have been resolved, failback
can be manually initiated. Once this is done, the screen is displayed on the secondary Cisco Prime Infrastructure
server. When you initiate failback, the Cisco Prime Infrastructure database on the secondary Cisco Prime
Infrastructure server and any other files that have changed since the secondary Cisco Prime Infrastructure server
took over Cisco Prime Infrastructure operation are synchronized between the secondary and the primary Cisco
Prime Infrastructure servers.

Manual/Automatic Options
Automatic Failover
Automatic failover is a much simpler process. The configuration steps are the same except that automatic failover
is selected. Once automatic failover is configured, the network administrator does not need to interact with the
secondary HM for the failover operation to take place. Only during failback is human intervention required.
Manual Failover
This is the recommended mode of Failover in Cisco Prime Infrastructure High Availability deployment. When the
secondary Cisco Prime Infrastructure server is configured with manual failover mode, the network administrator is
notified through an email that the primary Cisco Prime Infrastructure server has experienced a down condition. The
Health Monitor (HM) on the secondary Cisco Prime Infrastructure server detects the failure condition of the primary
Cisco Prime Infrastructure server. Because manual failover has been configured, the network administrator needs
to manually trigger the secondary Cisco Prime Infrastructure server to take over Cisco Prime Infrastructure
functionality from the primary Cisco Prime Infrastructure server. This is done if you log in to the secondary HM.
Even though the secondary Cisco Prime Infrastructure server is not running,
you can connect to the secondary HM
using the following syntax:
https://<Secondary_PI_IP_Address>:8082/
.
The secondary HM displays messages in regard to events that are seen. Because manual failover has been
configured, the secondary HM waits for the network administrator to invoke the failover process. Once manual
failover has been chosen, the message is displayed as The Secondary Cisco Prime Infrastructure Server
Starts. Once the failover process has been completed, which means that the Cisco Prime Infrastructure database
replication process is completed and the secondary Cisco Prime Infrastructure JVM process has started, then the
secondary Cisco Prime Infrastructure server is the active Cisco Prime Infrastructure server.
