Two ASA 5520 (ASA SSM-10) configured as active/standby failover, they can sync configuration no problem. The only issue is that one box will show Failed after a while -- whateve I configured it as primary or secondary, always the same box. I used debug fo ifc, it shows HW failed (mate=0) in this box. I suspect it is hardware issue, any idea?
AND Another big issue:
PRIMAY box won't get ACTIVE back once rebooted, stay STANDBY as if it were SECONDARY.
