Known limitations of mutually aware OpenSwitch

This section describes some known limitations with the mutually aware OpenSwitch feature.

Mutually aware support OpenSwitch does not propagate some functions

A mutually aware OpenSwitch does not propagate the following functions to its companion:

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.

Inconsistent mutually aware cluster setting causes error
