F5 Load Balancer - Active/Standy switching role controlling failover
Posted on 2014-04-02
Running 2 F5 load balancers in a Active/Standby role, running version 10.2.1.
Although in a normal failover scenario it works fine but, recently within the data centre they are hosted, there was a power issue and the Active lost power. The standby took control as expected. They use the serial connection to advertise each other. So, the power on the original Active was restored then lost a few times ,with the switch it was connected also not available. The result being, all connections were being sent to the Active which had no switch to send connections to or receive so causing timeout for traffic.
So, how do I in this scenario stop the "active" device on having power restored stop becoming the ACTIVE load balancer . Actual fail back needing a manual fail back not automated as in a Cisco ASA active/failover scenario.
