Configuring High Availability
Managing the Cluster
On the master of an HA cluster, the Sync Configuration Now button is active.
Figure 8-3. System > Settings > High Availability on the Cluster Master
■ Click Sync Configuration Now to propagate HA changes that you made to
the master to the other cluster members. If the members of the cluster
have different configurations when you synchronize the configuration,
the participant will be rebooted with the new startup-config.
To avoid unnecessary delays due to rebooting time, ensure that you have
saved the configuration to the master’s startup-config by clicking Save
before you click Sync Configuration Now.
When you save configuration changes to the master, you will be prompted to
synchronize the configuration to the participant. Because the participant must
reboot each time the configuration is synchronized, you should consider
making several configuration changes before synchronizing the cluster.
Depending on your situation, you might want to limit synchronizing the
participant with the master to 4 or 5 times per day.
Note The Rebalance Now button will be available in a future version.
