From the RAID controller BIOS, all you need to do is create a RAID array, and if possible a bootable partition(2GB) to install DSS V6 on to. If you cant do this, boot from another drive, or USB, etc...
Volume groups and Logical volumes can be created from the webGUI.
The problem you are having is most likely an unsupported RAID Controller(PERC4).
'No units found' is because DSS V6 is not seeing the RAID array.
