The best solution would be to be able somehow to run the avanced RAID utility... For that, I need a running OS where I could install it.
They don't have a bootable CD image with the tools? I am only familiar with the IBM ServeRAID adapters where you have such a tool.
Another option is of course to create a number of 2TB partitions and create a VG with all of them as PVs. Of course, you would need 6 partitions for this, but once you have them addded to a VG it is pretty seamless.
