I configured IPFailover between two Xserves running 10.2.6. If you follow the steps beginning on page 606 of the server admin guide exactly it works fine as far as the “primary server dies, secondary server takes over” part goes. Make sure that you don’t miss in step one that they are asking for the “broadcast addresses” not the ip address of the primary server. That one threw me off for a while.
The tricky part is doing failover scripts and getting processes to stop and start. There is very little (read that as no) documentation on scripting starting file sharing services for example. I ended up giving up and am going to use IPFailover in an “alert the admin with an email” mode instead of the take over ip mode. If you are running this on a webserver, starting that on failover is less complicated than starting file services, and there is some documentation around for that.
