About a high availability active-active configuration

You can ensure that you always have access to managed BIG-IP devices by installing two BIG-IQ systems with an active-active, high availability (HA) configuration. Any configuration change that occurs on one BIG-IQ system is immediately synchronized with its peer device. If a BIG-IQ system in an active-active HA configuration fails, the peer BIG-IQ system takes over the BIG-IQ device management that was previously done by the original device.

Configuring BIG-IQ system in an active-active high availability configuration

You must install and license two BIG-IQ systems before you can configure them in a active-active high availability pair.

Configuring BIG-IQ Cloud in a high availability pair means you always have access to all of the BIG-IP devices in your network. (Configuring a high availability pair is optional.)

Important: To synchronize properly, both BIG-IQ systems must be running the same version of software. The exact configuration in terms of hardware is not required; however, the systems should have comparable resources. This is required because, in the event of a fail over, the peer must be able to maintain the process requirements for both systems. This is especially important in terms of disk space and data collection.
  1. In the Peer IP Address field, type the self IP address (on the internal VLAN) of the peer system. Do not use the management IP address of the peer.
  2. Click the Add button to add this device to this high availability configuration.
  3. In the User Name and Password fields, type the administrative user name and password for the system.

If discovery 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.
