Not really.  You have to bring down the lock_gulmd processes in order to 
control the order.  You can try running `gulm_tool switchpending` on the 
master server.  That will force the master into the pending state, the only 
problem is that it might be the first one to recognize that there is no 
master and may come back as master again.  On the other hand, you may get
lucky and have the master switch to the machine that you want to be master.
