Looks like you have it plugged in to a 6Gb controller.  Try plugging it in to a 12Gb expander and 12Gb controller and see what happens.  We have some of those that refuse to probe at all when they’re attached to a 12Gb topology.  6Gb works ok, I think, but we do get those messages.  One of my co-workers is doing the debugging on that one, so I’m not sure whether some or all of the drives are having issues.
