Technical Tip: How to trigger HA failover with Override enabled

[ldsouza]

Description	This article describes how to trigger the HA failover when the HA 'Override' option is enabled.
Scope	FortiWeb.
Solution	One of the ways to trigger HA failover is by changing the device priority on the unit when the HA 'Override' option is enabled. When the HA 'Override' option is enabled, the device with the lower 'Device priority' is considered as the 'Primary' HA Role. Example: The devices FWEB-A and FWEB-B are part of an HA cluster. FWEB-A is the primary device, and FWEB-B is the secondary device in the HA cluster. To trigger the HA failover, the HA device priority of device FWEB-A has been increased from '5' to '9', where the HA device priority of FWEB-A is greater than that of FWEB-B. These changes resulted in HA failover, with the device FWEB-B taking over the 'Primary' HA Role.   Note: The FortiWeb node with the highest number of available monitored ports will be chosen as the active HA member, even if the set priority value favors the other member when override is enabled.  For more information regarding FortiWeb High Availability active member election, refer to this document: FortiWeb Administration guide
