Any chance you can download the Demo-CD of DSS from link below. I want to see if it will work with this or not. Also are you able to use the Adaptec Storage Manager from a another system to access it. We don't have ingrate GUI access for Adaptec only for 3Ware, Areca, HighPoint and Promise.

From the BIOS of the Adaptec once creating the RAID sets you should see them in the Volume Manager - though there might be something in the BIOS preventing us from seeing the RAIDs just not sure what it could be as it should be simple. Try testing with the with just the drives as single drives just to see if we are seeing them independently from the GUI SW RAID tool.

If possible go to Status > Hardware > Logs > then click on the Download button and download the logs. Look at the dmesg log to see any errors from the Adaptec controller or drives.

Test with the DSS Demo-CD
