It's all just a physical interconnect difference. The problem you are describing is a non-functional SCA->wide adapter. I have yet to ever find a simple wide<->SCA adapter that worked. I've always had to have a real SCA backplane before things worked properly. -- Doug Ledford 919-754-3700 x44233 Red Hat, Inc. 1801 Varsity Dr. Raleigh, NC 27606
