Configuring system settings : Using high availability (HA) : Example: Failover scenarios
Example: Failover scenarios
This section describes basic FortiMail active-passive HA failover scenarios. For each scenario, refer to the HA group shown in Figure 15. To simplify the descriptions of these scenarios, the following abbreviations are used:
• P1 is the configured primary unit.
• S2 is the configured secondary unit.
Figure 15: Example active-passive HA group
This section contains the following HA failover scenarios:
• Failover scenario 1: Temporary failure of the primary unit
• Failover scenario 2: System reboot or reload of the primary unit
• Failover scenario 3: System reboot or reload of the secondary unit
• Failover scenario 4: System shutdown of the secondary unit
• Failover scenario 5: Primary heartbeat link fails
• Failover scenario 6: Network connection between primary and secondary units fails (remote service monitoring detects a failure)
