Okay, as long as makedns -e updates the external named server just like it would a local named instance. The reason I had asked that is because the documentation was rather ambiguously worded on that point. So now I'm just trying to figure out the best way to make xCAT only update the external DNS instance. Since you said that you have the problem of the local deamon starting up regardless when you run makedns -e, have you ever noticed whether it is actually updating local records also? Is your /var/named/ directory on the xCAT server populated with zone files? Also did you remove the MN's local host IP (whether loopback or assigned) from its /etc/resolv.conf and make it point only to the external DNS server's IP?
Since I'm trying to transition without an outage I think I will have to have a brief period where I have both the MN and the external server running identical named configs. Then I can slowly begin to move my compute cluster nodes to resolve to the external server in 10 node increments or so, so that I can troubleshoot any problems and undo it to resolve back to the MN again if need be. I just want to be as careful as possible.
