Yeah, it's the utility "MAKEDEV", which probably can't create those entries
without the patch that James provided 8^). You may, if you're brave, want
to take a look at the MAKEDEV script, and see if you can find anything on
'/dev/hdl' or 'hdl'. If there isn't anything there, then you'll have to add
something to the script that tells it how to create those devices. If you
look in devices.txt again, you will see that hdl requires a major device
number of something like (I'm making this up, CHECK IT!) 57. Minor numbers
will vary with the entry that you are creating. Since this is WAY off topic
for RAID, you can email me privately if you need help creating the
appropraite entries for these devices. I learned about that the fun way
when I built a machine with 28 CD-ROM drives (what does NT do when it gets
beyond 26 drives?).
