Did you follow all these instructions which include running makedhcp -n and makedhcp -a. https://sourceforge.net/apps/mediawiki/xcat/index.php?title=Changing_the_Service_and_compute_nodes_Hostname_and/or_IP#Changing_the_Hosthame.2FIP_address_on_the_Linux_nodes_managed_by_xCAT Is your network table correct. Did you run nodeset?

I deleted the old /etc/dhcp/dhcp.conf and created a new one with makedhcp -a and renamed the files in /tftp/xcat/xnba/ to match the new network.
