Configuring the HA mode and group
The Configuration tab in the System > High Availability submenu lets you configure the high
availability (HA) options, including:
• enabling HA
• whether this individual FortiVoice unit will act as a primary unit or a secondary unit in the
group
• network interfaces that will be used for heartbeat and synchronization and virtual IP
• service monitor
HA settings, with the exception of Virtual IP Address settings, are not synchronized and must be
configured separately on each primary and secondary unit.

Description
master master Normal for the primary unit of an active-passive HA group.
slave slave Normal for the secondary unit of an active-passive HA group.
master off The primary unit has experienced a failure, or the FortiVoice unit is in
the process of switching to operating in HA mode.
HA processes and call processing are stopped.
slave off The secondary unit has detected a failure, or the FortiVoice unit is in
the process of switching to operating in HA mode.
After the secondary unit starts up and connects with the primary unit
to form an HA group, the first configuration synchronization may fail
in special circumstances. To prevent both the secondary and
primary units from simultaneously acting as primary units, the
effective HA mode of operation becomes off.
If subsequent synchronization fails, the secondary unit’s effective
HA mode of operation becomes master.
master failed The remote service monitoring or local network interface monitoring
on the primary unit has detected a failure, and will attempt to
connect to the other FortiVoice unit. If the problem that caused the
failure has been corrected, the effective HA mode of operation
switches from failed to slave, or to match the configured HA mode of
operation, depending on the On failure setting.
master slave The primary unit has experienced a failure but then returned to
operation. When the failure occurred, the unit configured to be the
secondary unit became the primary unit. When the unit configured
to be the primary unit restarted, it detected the new primary unit and
so switched to operating as the secondary unit.
slave master The secondary unit has detected that the FortiVoice unit configured
to be the primary unit failed. When the failure occurred, the unit
configured to be the secondary unit became the primary unit.
