Hi everyone,

Just another Quick Followup: What a difference did the Dell cable make. No 
more SAS_A errors and everything boots up fine. The SAS-B cable isn't 
connected (hence reducing my drive bays from 6 to 4) an reported an error, 
which I cleared using omconfig, but this will do for now. My T410 works 
very fine and actually has its 3Tb drives connected at 6GBps.
Thanks for the help!

Vincent
