Cisco ASA standby failed - pls help

[secureIT]

Hi Friends,

In my ASA 8.4(7)30 HA setup, i do see standby failed when i run show failover in Primary FW (Active) as given below.

Primary - Active FW

# show failover

This host: Primary - Active
Other host: Secondary - Failed

Secondary - Standby FW

# show failover

This host: Secondary - Standby Ready
Other host: Primary - Active

I have executed below debugs in the standby FW, and got few logs.

debug fover verify
debug fover fail
debug fover sync

Hello,

Could you kindly please, check the status of the interface that works as the failover link, and attach a show failover and show failover state.

Hi Kornelia Gutierrez, Please find the attached logs from both the firewalls.

[secureIT]

pls find the attached show failover logs from both the firewall, i think i need to reboot the secondary standby firewall - what do you say ?

[Pawan Raut]

Please check first if you are able to ping Management interface IP of each other. If no then check cable connectivity between this two. If still see the issue you can reboot the standby unit but make sure yous should do this in non production hours because it has risk of both unit become Active at a time.

Hi, 

in case of reboot a standby Unit i disconnect all interface cables and connect only failover interface cable.

Then wait for negotiate failover active and passive then connect all other cables again

In this case there is no risk that both units become active

Regards Marco

Ok Marco, By seeing the debug logs and show failover outputs of both Fws, I seriously suspect issue with standby fw only, so I will go ahead remove all the cables except Mgmt0/0, reboot the Standby fw, then i will connect cables one by one.

[Marco Soeder-Schuettler]

Yes, so you can do ;-)

Make sure that active / passive negotiation is already done.
