Failover, but not fail back

Hello All,

 

 

I am back.. sorry this sat so long, but I am having an issue with this. For some reason, the tcp connection goes down occasionally between the F5 and my application. This triggers the other node to now recieve the requests. I know the connection should stay up, but it is going down, and really causing a problem. Is there anyway to get this to failover only if one of the monitors for the node triggers the node being marked down?

 

 

The other problem that I am facing with this solution is that if for some reason a switchover does occur because the tcpconnection goes down, I don't get any notifications. I.e. there is no snmp event, or even anything in the ltm log to indicate that the switchover has occurred...

 

 

Any other thoughts on this would be greatly appreciated!

 

 

Thanks
