I have a pair of firewall 5520 which is running 8.2(5) image.
Recently I am facing the "HA state progression failed" failover issue in the secondary unit which forces the secondary unit to failover disabled stage.
Any body have idea why it is happening.
Both firewalls are directly connected. for the troubleshooting purposed I had changed the failover cable and other cables of secondary unit as well. this incident happened three times in last two three week. i had not done any changes regarding the failover concern.
some outputs Running config interface Management0/0 description LAN Failover Interface
