Irule question about Hash persistence

I'd suggest just doing the following:

Removing the hash persistence profile, add a cookie insert persistence profile and testing?

If the persistence fails, you might need to hardcode the domain on the persistence cookie using an iRule like this. You'll need to update the persistence cookie name and the domain you want to set it with. Make sure to prepend a period to the beginning of the domain (ie .aaa.com, not aaa.com).

 
 when HTTP_RESPONSE { 
  
     Check if persistence cookie has a value 
    if {[HTTP::cookie "BIGipServerMy_pool_name"] ne ""}{ 
  
        Set domain on the persistence cookie 
       HTTP::cookie domain "BIGipServerMy_pool_name" ".aaa.com" 
    } 
 }
