DHCP is not an option here. In the event of a real disaster, we use the production IP s and hostnames, full replication, all is easy peasy. But for a disaster test, we can't - have to change IPs and hostnames. This can be problematic, but after a while, you make a list and figure it out - not everything uses DNS (think firewall, perhaps load balancers, some stupid sw :).
In SuSE 9 and 10, the files that are going to perhaps need attention are /etc/HOSTNAME /etc/hosts /etc/sysconfig/hwcfg-qeth-bus* /etc/sysconfig/network/ifcfg-qeth-bus-ccw-x.x.xxxx /etc/sysconfig/network/routes /etc/resolv.conf We also regenerate server SSH keys on a change of the HOSTNAME.
