That's not in the kernel but in udev/systemd's process of creating the symbolic links in /dev/disk/by-id/. It gets /dev/sd[h-l] and /dev/sd[h-l]1 as kernel generated device files. But sd[ij] and also sd[hl] show pair-wise the same serial numbers. In case of sd[ij] the outcome is mixed: links to sdi and sdj1 survive. In case of sd[hl] we see a less strange outcome: sdh and sdh1, while sdl and sdl1 are missing. The open question (at least to me) is whether it's the disks or the controllers or the drivers which cause the duplication. Have a nice day :) Thomas
