I don't see any /dev/sgX in the dmesg discovery, so the first thing
I'd check is if the scsi init the kernel is doing is scanning all
LUNs. Many times the robotic part of the drive has the same bus
address, but the next higher Logical Unit Number.
Linux kernels do not "scan all luns" by default, it has to be turned
on in the .config file and the kernel rebuilt and reinstalled.
