hmm...

The way I'm set up is;

Use hardware raid bios util to set up my raid,
Boot and run open-e DSS v6 from a USB-DOM,
use web interface and goto, config->vol manager->vol groups
Select your unit and create a new volume group.

then set up an iSCSI target or setup as a NAS.

you've not got open-e installed on the disks you want to use for storage have you?
I think the software has to be on a seperate unit from your storage.

Hope this helps,
Jon
