This is a description of how to use Razor to install a system, it's a WORK IN PROGRESS. 

All this commands are to be executed in =phoenix1.lcg.cscs.ch=, but the server =inst.lcg.cscs.ch= is the one actually serving the images.

   * Get info on the node =scratchy03= <verbatim>
$ ~miguelgi/bin/lcg_list_razor_nodes |grep scratchy03
node14 | razor IP: "10.10.64.32" | razor hostname: "node14.lcg.cscs.ch" | public IP: 148.187.64.32 | real hostname: scratchy03.lcg.cscs.ch |

$ razor nodes node114
From http://localhost:8080/api/collections/nodes/node114:

   * Reinstalling the node <verbatim>
$ razor reinstall-node --name=node115
$ ~miguelgi/bin/lcg_ipxe scratchy03</verbatim>

   * IPMI console<verbatim>

   * =test57= is an example system to be provisioned. In green are the steps taken by the provisioning system.
   * =inst= holds the following services: =DHCP= =PXE= =HTTP proxy:80=
      * =DHCP= is configured via Puppet
      * =PXE=: =TFTP= and =HTTP repo:81= are run from =/cm/www/html= mounted in read-only mode.
      * =HTTP proxy:80=: running a transparent proxy to =phoenix1= for Razor server. This allows systems to fetch the Razor configuration using the 10.10.64.0/22 network.
   * =phoenix1= runs the razor server and puppet+puppetdb server. 
      * The =HTTP repo:81= runs off =/cm/www/html/= and is shared with =inst=
   * =cfengine.lcg.cscs.ch= (not shown in the diagram) runs cfengine for all those machines still configured via CFengine2
