Rebalancing can be done either manually or automatically. By default the policy is Automatic Failback.
With the rebalance policy set to Automatic Failback, the only times that a rebalance operation is triggered is when there is a change to :
- The cluster membership
- The cluster's external network configuration
- A member network interface
When set to Manual Failback, the policy does not redistribute IP addresses until a rebalance command is issued via the command line or Administrative Web Interface.
