I use an USB stick with debian wheezy /dev/sda to boot an system and
login over ssh.

Then I add two more USB sticks to the system /dev/sdb and /dev/sdc

The bellow is what I do. If I do these steps on an HP Z600 the system
will boot fine, if do this on an HP ML110G7 grub goes to disk not found
(both with grub v1.99 and v2.00) I got the feeling somethings goes wrong
around the mdadm part....
