Thanks to Dr. Thomas Blinn and Rich Glazier for helping out on this one.

The question was:

> 61: 13 xxx tape none 0 1 tape2 [0/6/0]

I never did quite figure out where they came from, as they were there after
the initial installation, but now I know how to get rid of them. Suppose,
in the above example, I wanted to have cdrom0 the correct device and get rid
of that cdrom1 ( I only have one CDrom on this box, honest ).

# hwmgr del scsi -id 56, in this case, gets rid of that null cdrom device

Now I want to have cdrom0 correct, so I do:
# dsfmgr -m cdrom1 cdrom0

If I had blown away the cdrom1 device as well, a hwmgr scan scsi would have
brought it back as cdrom2. Then I could have done

# dsfmgr -m cdrom2 cdrom0
