v11.0 HA Configuration issue...

Hi there, I'm in the process of configuring our new Big IP 3900 devices... They started at v10.2, and I was able to successfully configure a HA pair. I then went and performed the upgrade...

When I've had this issue recently I fixed it be doing the following:

 

 

1) upgrade to v11.1

 

2) delete the existing trusts on both units and reset device trust on both units

 

3) double check the configuration of the ip addresses for config-sync and failover

 

4) re-add the standby unit to the trust from the active unit

 

 

Of course if you want to do this on a live pair you'd want to be careful not to inadvertently trigger a failover situation with a config on both devices, so maybe also resetting the standby unit to it's base config before starting this process (making sure to make UCS's of the working config, etc).

 

 

Hope that helps!
