 # workflow for a new ecmc server
 
-## A bit unclear
-* Setup ILO, 8213 (maybe hardware group)

 ## hardware group (Kurt)
 * Order servers (keeps stock)
-* Add server to packet-fence (default to office network)
-* Add users to ecmc server
-* Add hostname (need info from controls)
+* Add ILO network interface to packet-fence (default role: office network)
+* Add ILO hostname if provided in advance, otherwise controls needs to take care
 * Keeps inventory up to date
 * Sometimes equips with **empty** usb stick
 * Install (power and network)
 
 ## controls
 * Update boot parameters to boot from usb
+* Add network interface to boot from (e.g. eth0) to packet-fence
+* Set [role](#packet-fence-roles) in packet-fence for ILO and boot network interfaces
 * [Prepare usb stick](#prepare-usb-stick)
 * [Add host to warewulf config nodes.conf](#Add-warewulf-conf)
-* [Add host startup cfg](#Add-ecmc-server-cfg)
-* Configure IOC:s
+* [Add host startup cfg](README.md)
