A mutually aware OpenSwitch does not propagate the following functions to its companion:
rp_pool_addserver
rp_pool_remserver
rp_pool_addattrib
rp_pool_remattrib
rp_pool_cache
If you issue any of these commands on a companion server, manually repeat the commands on the other companion. In addition, check that your coordination module applications do not contain the equivalent of these commands. If they do, you must find a way to notify the administrator when the commands are called by the coordination module, so that the administrator can manually repeat the same commands on the other companion OpenSwitch.
