I have experiensed failover failure on the new instalation of pair of ASA 5510 7.2(2). I use multi context mode but actualy in Active/Standby mode. Only the reason fro multi context is the preemtion option only supported in multiple mode.
The problem is that after restart of the primary/activ box it fall in to state "failover off" or "could standby".
Only recovery procedure to get the failover up and running is switch off the secondary box, restart the primary and finaly switch on the secondary again.
This behavior was seen only when restarting the active. If I simulate other failure e.g. interface disconnect it works fine.
Can someone advise if:
1. Configuration with single failover group is valid ?
2. If someone experienced similar behavior. Or have any idea.
See the failover configuration:
failover lan unit primary
failover lan interface failover Ethernet0/3
failover polltime unit 2 holdtime 10
failover key *****
failover link failover Ethernet0/3
failover interface ip failover 192.168.254.1 255.255.255.252 standby 192.168.254.2
failover group 1
polltime interface 2 holdtime 10
Thanks for any ideas.
