open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you
are root.

Expected Results:  output should show details about my cdrw drive

Additional info:

[root@box root]# ll /dev/cdrom
lrwxrwxrwx  1 root root 8 May 16 17:01 /dev/cdrom -> /dev/hdc

I have mounted cds, and have used the burner with Fedora Core 1 with
the ide-scsi kernel option.

Comment 1 Andy Blyler 2004-05-29 04:23:12 UTC
ide-scsi=hdc was in the grub.conf, and was not removed during the
upgrade process.  After removing ide-scsi=hdc, the results from
`cdrecord -scanbus` are what are to be expected.

Comment 2 Harald Hoyer 2004-06-04 10:52:32 UTC
anaconda is to be blamed

Comment 3 Jeremy Katz 2004-06-04 21:11:39 UTC
Can you attach your grub.conf?

Comment 4 Target 2004-08-23 04:17:46 UTC
I had a similar problem and tracked it down to an ide-scsi parameter
that should not have been copied over by anaconda during the update to

The entry in grub.conf as created by anaconda:
title Fedora Core (2.6.5-1.358)
        root (hd0,1)
        kernel /boot/vmlinuz-2.6.5-1.358 ro root=LABEL=/  hdc=ide-scsi
        initrd /boot/initrd-2.6.5-1.358.img

hdc is a cd burner. The max luns entry is unrelated; it was added to
keep a 6-in-1 USB memory card reader from producing dozens of
duplicate scsi entries.

You might want to roll this and other similar bugs up into a single
one. There's a whole host of cdr- and dvd-related symptoms caused by
the retention of that boot parameter.
