I was using a qlogic HBA for my tests, so I don't think this is the problem -- although the original poster claims to have 64 targets, and I had only one target with 128 luns (attached 4 times). -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
