About a high availability active-active cluster
You can ensure that you always have access to managed BIG-IP devices by installing two or more BIG-IQ systems in an active-active, high availability (HA) configuration. Any configuration change that occurs on one BIG-IQ system is immediately synchronized with its peer devices. If a BIG-IQ system in an active-active HA configuration fails, a peer BIG-IQ system takes over the device management.
Configuring BIG-IQ System in an active-active high availability cluster
You must activate a license on two or more BIG-IQ systems
before you can configure a high availability cluster.
Configuring a high availability cluster ensures that if one BIG-IQ system
goes offline, another BIG-IQ system can continue managing your devices without
interruption.
If discovery of the newly configured BIG-IQ system fails, a Delete button displays. Verify the correct self IP address and credentials. Then click the Delete button to remove the incorrect information, and re-type the self IP address, user name, and password.
