Depending on your grade of server automation and provisioning, this may also include lun assignment.

Some admins rely on initial deployment and have a configuration management tool (floss: puppet, cfengine and the like; commercial: e.g. hp server automation) that may be used to restore a server to a known state.

You may also have a look at Clonezilla (http://clonezilla.org/) and System Imager (http://wiki.systemimager.org/index.php/Main_Page) that may deploy a previously saved image of a server.

Other users may put the whole storage to a san and use snapshot techniques to freeze a server state so that they can recover it easily.

As you see, there are many roads to Rome...
