How to install a machine with Razor

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

$ ~miguelgi/bin/lcg_list_razor_nodes |grep scratchy03

$ razor nodes node114

Reinstalling the node

$ razor reinstall-node --name=node115
$ ~miguelgi/bin/lcg_ipxe scratchy03

IPMI console

The provisioning system

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
