I assume this is something todo with the promise bois not setting up the 3rd card at boot time. It only shows drive listing for 2 of the 3 cards. Unfortunatly this generated another problem. When read from both drives at the same time it functions normally and see resonable performance. When i attempt to write to both drives it will cause the machine to lockup.
