Choose the server you want to be active

If you want a server in your HA pool to be the active server as much as possible, for example, if one server has better hardware specifications, you can choose it as your preferred active server. When a preferred active server fails over, manually or automatically, to the standby server, it will failback to the preferred server when the preferred active server's status is UP.

By default, no preferred server is selected and automatic failback is not enabled.

You cannot select a passive pool member when you create your pool.

  1. Select your pool.
  2. In the Commands menu, click Edit Pool.
  3. Expand Preferred Server Settings.
  4. Select the server you want to failback to in the case of a failover.

When a failover occurs, the active server fails back to the preferred server when the preferred server is healthy again.

If the standby server is selected, the server fails over to the preferred server as soon as you save your changes.
