FortiManager high availability (HA)

A FortiManager HA cluster consists of an active master unit, and up to four standby slave units. If the master unit becomes unavailable, one of the standby slaves will become the new master.

In most situations, the FortiPortal provides access to the master FortiManager in the HA cluster. Configuration changes in the master will be synchronized to the slave units. If no master exists, the FortiPortal provides read-only access to the slave units.

When a FortiManager unit with an HA configuration is added to FortiPortal, FortiPortal must be able to reach all the IP addresses that are part of the FortiManager HA cluster (including the slave). If FortiPortal cannot reach the slave IP address, FortiPortal cannot detect the HA switchover.

In the FortiManager table, the Mode includes the following values:

• Standalone—the FortiManager is independent of a high-availability cluster
• Master—the FortiManager is the master in a high-availability cluster
• Slave—the FortiManager is a slave in a high-availability cluster
