Cheap Fail Over
Zones in Solaris can give you a poor man's fail over. My environment doesn't require extreme reliability so this won't work for everyone. What I do is setup a zone on another physical server identical to the production zone, with the exception of the ip and autoboot is set to false since I leave it dormant when not in use. If the production server needs to goes down then all I need to do is change the ip in zonecfg and sys-unconfig the zone. The sys-unconfig is needed for all the stuff in /etc. It is the easiest and most full proof method.
