Why is this a bug? What would happen when I telnet into the the RAID box and enable my volumes on those LUNs?

16384 LUNs for Fibre Channel. As you see, scanning is out of the question. You must issue REPORT LUNs and fall back on scanning if the device reports a check condition. I did that when I worked in Sun Storage with A5000/A3500/T3 arrays couple of years ago.
