Upgrading an Existing Failover Pair For instructions on how to upgrade an existing failover pair to a new Cisco NAC Appliance release, see "Upgrading High Availability Pairs" in the Release Notes for Cisco NAC Appliance corresponding to your latest Cisco NAC Appliance release version. Failing Over an HA-CAM Pair Warning To prevent any possible data loss during database synchronization, always make sure the standby CAM is up and running before failing over the active CAM. To failover an HA-CAM pair, SSH to the active machine in the pair and perform one of the following commands: • shutdown, or • reboot, or • service perfigo stop This stops all services on the active machine. When heartbeat fails, the standby machine will assume the active role. Perform service perfigo start to restart services on the stopped machine. This should cause the stopped machine to assume the standby role. 4-16 Cisco NAC Appliance Hardware Installation Guide OL-20326-01

Failing Over an HA-CAM Pair
Warning
To prevent any possible data loss during database synchronization, always make sure the standby
CAM is up and running before failing over the active CAM.
To failover an HA-CAM pair, SSH to the active machine in the pair and perform one of the following
commands:
shutdown
, or
reboot
, or
service perfigo stop
This stops all services on the active machine. When heartbeat fails, the standby machine will assume the
active role. Perform
service perfigo start
to restart services on the stopped machine. This should
cause the stopped machine to assume the standby role.
