When you created the 2GB volume did you make sure that it was a desperate 2GB volume from the RAID set and then make it the first boot order as well. You should be able to see your RAID array and if you are able to see the drives and controller to configure from the GUI in Setup > HW RAID then the DSS V6 is seeing the PERC 6. You can try to use a USB Flash stick to test with and create the RAID array from the DSS V6 GUI to test without the 2GB volume.
