Failing Back
Once failover has occurred and the primary firewall is alive in standby mode
and the accessory firewall is alive as the active, a failback does not automatically
occur.This is because there is no acumen to about-face the alive and standby
firewalls (especially if you are not application stateful failover).When the primary firewall
is repaired and the bootless action has been fixed, it does not automatically
become the alive firewall (unless the accessory firewall now fails!).You can force
the primary firewall to become alive in one of two ways:
Use the failover alive command on the primary firewall.
Use the no failover alive command on the accessory firewall.
After you use one of these commands, the primary firewall will become
active. If stateful failover is enabled, all access will be maintained and no
sessions will be dropped. If, however, stateful failover was not enabled, connections
will be alone and applications will accept to re-establish sessions through
the firewall.
