Technical Tip: Additional GUI support for HA operation

Description

This article describes the additional GUI support for HA operation that is introduced in FortiOS 8.0.

Scope

FortiOS 8.0.

Solution

To access the additional GUI support:

1. Go to System -> HA.

2. Select HA cluster member.

3. Select 'Diagnostics and Tools'.

Additional GUI support includes:

1. Force resync:
   This forces synchronization of all secondary devices to primary FortiGate devices. Force resync is greyed out when HA is in-sync.
   
   

2. HA status:
   HA status tab shows Disk Status, Storage information and size, cluster member checksum, session status, system memory usage, and heartbeat interface status.
   
   

3. Config diff:
   Displayed differences in the configuration of HA cluster members make it easier to monitor status and identify configuration mismatches directly from the GUI.
   
   

4. Actions:
   Under the Action dropdown option, there are 'Show matching logs' and 'Force HA Failover/Undo HA failover'.
   'Force HA failover' is equivalent to 'execute ha failover set <virtual cluster id>' command while 'Undo HA failover' is equivalent to 'execute ha failover unset <virtual cluster id>'. For more information refer to Technical Tip: How to use failover flag to change Active unit.
