Each pool is independently controlled based on the health monitor attached. Unless the server in question does not respond to a ping, the icmp monitor would report port 10000 as available.

 

You have a few options:

 

 

1. For maintenance, disable the node on the F5 which will offline it in all pools associated

 

or

 

2. Implement a TCP or script monitor that can accurately assess the status of the TCP service listening on 10000

 

or

 

3. Implement a HTTP monitor with an alias port of 10001 that will mark the TCP service down if the HTTP service is unavailable.

Good luck!
