QUESTION:                                                                       
                                                                                
My customer has the following scenario:                                         
                                                                                
-  RS/6000 34H/"A" with 2 Xstations using it as primary boot server             
   and machine "B" as secondary boot server (Xstations "1" and "2").            
                                                                                
-  RS/6000 34H/"B" with 1 Xstation using it as primary boot server              
   and machine "A" as secondary boot server (Xstation "3").                     
                                                                                
They will be bringing the "B" machine down frequently.  They have               
tested bringing "B" down and when rebooted Xstation "3" comes up                
fine off of the "A" machine, so no problems there.                              
                                                                                
My questions are:                                                              
                                                                                
1) I understand that the Xstation must be rebooted after "B" goes               
   down, is this true or is there a way for it to just switch                   
   automatically?                                                               
                                                                                
2) To perform maintenance on "B" they would like to do the following:           
   While machine "B" is still up, on Xstation "3" (which has booted             
   off of "B" but is now up) simply login to machine "A".  Then they            
   would like to take "B" down without disturbing Xstation "3" which            
   booted off "B" but is now logged onto "A".  Is this possible?                
                                                                                
---------- ---------- ---------- --------- ---------- ----------                
A:  Your understanding is correct, you must reboot.                             
                                                                                
    No, the Xstation gets its fonts from the boot host and relies upon         
it for paging, therefore, if it needs either it will not function proper-       
ly.                                                                             
                                                                                
---------- ---------- ---------- --------- ---------- ----------
