I have an issue with my F5 load balancer configuration with SharePoint.
I have 4 Web Apps. All are configured to use port 80. I have dedicated IP address for each Web App. I am using the Http Probe from F5 and it is working fine when everything is up and running.
However, the issue is when I stop one Web App on one of the WFE, I expect the Load balancer to detect it and stop sending requests to only this server. This isn’t happening. F5 will detect it if I stop all IIS on all servers but if one Web App is still running then the F5 probe will fail to detect it.
I am wondering if you face the same issue and what solution you implemented?
I’ve seen this issue before too. What does the probe look for? It’s probably not looking at the right criteria.
