ASA failover did not work

Hi,

I am having ASA 5520 with active/standby configured. Around 2 days ago, the ASA stopped responding & all of my websites stopped working. when i checked the failover status it said that failover is off. I had to manually turn the failover to start my traffic flow.During this time my secondary ASA was not responding. After some time, the primary stopped responding & secondary became active......to solve this i had to make the secondary unit as failover unit primary & the primary unit as failover unit secondary.

i did get a log on ASA :-

“(Primary) Disabling Failover” with error message no.105001 which states the below:-

Error Message %PIX|ASA-1-105001: (Primary) Disabling failover.

Explanation In version 7.x and later, this message may indicate the following: failover has been automatically disabled because of a mode mismatch (single or multiple), a license mismatch (encryption or context), or a hardware difference (one unit has an IPS SSM installed, and its peer has a CSC SSM installed).(Primary) can also be listed as (Secondary) for the secondary unit.

Also i am attaching the logs captured during the incident.

I just want to know that why did the failover turned OFF.

Thanks

Pratik

Please share the output of the following from both ASA:

- show version

- show int ip brief

Also check that the failover interface is up on both ASA.
