Hi Dennis, beforehand let me say, though working for big blue I'm not official xCAT support...
Is this what you're looking for? http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Changing_the_Service_and_compute_nodes_Hostname_and/or_IP Static IP addresses should be set in the hosts table. Now there are many ways to change table entries... one would be to "tabedit hosts" and use vi command to search and replace. (See http://www.felixgers.de/teaching/emacs/vi_search_replace.html ) Important is to delete the old DHCP config: "makedhcp -d noderange" and after the table entries have been changed, "makedhcp noderange". See the makedhcp man pages for details. ...a comment on this: "static" IP in xCAT would mean that this node always gets the same IP address from the DHCP server. If you have stateful nodes with static IPs (in this case you probably have used the hardeths postscript) just write a simple shell script that changes the respective ifcfg file on the nodes. You can use vanilla tools like updatenode or even xdcp and xdsh to run it.
