Hi Lissa, Thanks for the reply and you have made a very good point here. It is very difficult to make xCat to be aware of the places where the IP needs to be changed. Really appreciate your reply.

I am really concerned about definitions in the system, such as /etc/sysconfig/network-scripts/ifcfg-eth0:IPADDR=9.114.47.11 that will need to be updated. It would be beyond the ability of xCAT to fix up all these system files on every possible OS we support. There are probably other applications that may store the ip address when installed that we don't even know about. It would be an interesting exercise to see how many places a nodes ip address is stored on the node. Lissa K.

Lissa, I'm trying to change the IP for the moment. The reason I put hostname also is because it was mentioned in the wiki that I found. It does make a lot sense to have the system reinstalled to make sure the settings are all in place with latest config. Just thought it might be a good idea if we provide the ability in xCat to enable changing of hostname and/or IP address without having to reprovision?

Are you just trying to change the hostname or are you also trying to change the ip address. If ip address, then I believe reinstall will be the best way to make sure all the system config files are set correctly. I think you would want to reinstall just to make sure you changes really worked, so if you have to reinstall in the future you will have no issues. Lissa K.

Dear All, When I'm searching for a solution to change IP/hostname for a compute node, I've found this article: http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Changing_the_Service_and_compute_nodes_Hostname_and/or_IP The article per se is great for addressing the issue but the solution seems require a reprovision(reinstall) of the node. So I wonder if there's a way to do the same without a reprovisioning?
