<DIV><FONT face=Arial color=#000000 size=2>I am in the process of developing a DR (disaster recovery) plan for my primary masters. Could someone please confirm (or correct me) that a second server in the "masters {}" statement of a slave zone will only be used in the event that the first master cannot be reached? Example:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>zone "example.com"{</FONT></DIV>
<DIV><FONT face=Arial size=2> type slave;</FONT></DIV>
<DIV><FONT face=Arial size=2> masters {</FONT></DIV>
<DIV><FONT face=Arial size=2> 1.1.1.1; // primary-master</FONT></DIV>
<DIV><FONT face=Arial size=2> 2.2.2.2; // primary-master backup</FONT></DIV>
<DIV><FONT face=Arial size=2> }</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I only want 2.2.2.2 to be used when 1.1.1.1 is not available.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I plan on writing a script to add the primary-master backup's IP address to the masters statement of all slave zones as well as replacing "type: slave;" with "type: master;" and removing the masters {} statement from the primary-master backup zones (which are currently slave zones) which will become master zones in the event of a failure.</FONT></DIV>

<DIV><FONT face=Arial size=2>All servers are running the most current EL5 BIND package.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any input or suggestions?</FONT></DIV><FONT face=Arial size=2>
