===Preparing the HDA===
1. Unmount and then, after turning off the server, physically disconnect all drives. If you are using Greyhole, check out the [[Reconnect existing Greyhole storage pool]] page. This will allow you to disconnect the data drives, and only risk the OS drive. Turn the server back on again. {{Code|umount -a} 2. Change the interfaces file to reflect eth1, not eth0:
{{Code|sudo nano /etc/network/interfaces}}
iface eth1 inet dhcp
32. Save using ctrl+x, and hitting "y" to confirm
43. Note the hardware address of the network card:
{{Code|ifconfig}}
54. Shutdown the server:
{{Code|sudo shutdown now -h}}
