Grolle,  From within the Raid Controller, what is the status of the Array? Also, was the raid 1 initialized after it was created? If not then that will need to be done before you try to install.  If you download this and boot to the LifeCycle Controller (F10) then select Deploy OS, from there load  those files and proceed with the OS install.  [URL] Let me know how the install goes.
