Best Practice for Sync Between Primary and Failover

I have an Automated F5 Draining solution that would drain our servers. When I wrote this I assumed there was only 1 F5. But now I've realized in production environment, we would have 2 F5(1 Active and 1 standby).

 

 

So I was trying to figure out how should I change my design.

 

 

I thought I'll always get both(active and passive) F5 APi's address.

 

- First figure out which one is active.

 

- Do all my operations in active F5

 

- Do a Synch operation

 

 

This's going to be my constructor;

 

public F5API(String loadBalancerAddress1, String loadBalancerAddress2, String userName, String password)

 

{

 

 

F5Interface.initialize(loadBalancerAddress1, userName, password);

 

if (F5nterface.SystemFailover.get_failover_state() == iControl.SystemFailoverFailoverState.FAILOVER_STATE_STANDBY)

 

{

 

F5interface.initialize(loadBalancerAddress2, username, password);

 

if (F5nterface.SystemFailover.get_failover_state() != iControl.SystemFailoverFailoverState.FAILOVER_STATE_ACTIVE)

 

{

 

throw new Exception("No active F5's found");

 

}

 

}

 

}

 

 

After I do my operations, how do I synch with StandBy F5?( How do I do it in c??) Or do we have "auto-configsync" right now and I don't have to do anything.

 

 

Thanks,
