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.

Subject: [LINUX-390] Dynamicallhy Changing Linux Guest Network
Does anyone have a z/vm and/or linux script that they could share that can
be used to dynamically change the linux servers network when the server is
brought up at a dr site and/or when the network addressing is changed?
I've tried playing with it without success - keep missing a piece here or
there.

I never guess. It is a capital mistake to theorize before one has data.
Insensibly one
begins to twist facts to suit theories, instead of theories to suit facts.
