Are the HA nodes different to the production ones in any way? I take it they are not running all the time? How long have you waited after enabling the HA Pool Members.

 

 

I'd suspect an ARP issue or similar here. Have you ever tried clearing the F5's TMM/LTM ARP cache? Is Reciprocol Update enabled?

 

 

Keep in mind that even when disabled the device will continue to monitor Pool Members and perhaps, if they are unavailable for a long time, retries max out etc.
