Hi,
I have the following devices in my system:
hda: SONY CD-RW CRX195E1, ATAPI CD/DVD-ROM drive
hdc: HL-DT-ST GCE-8526B, ATAPI CD/DVD-ROM drive
hdd: Toshiba DVD-ROM DSM-1712, ATAPI CD/DVD-ROM drive
I want my hda and hdc to be ide-scsi device, while hdd being ide-cd.
This is my /etc/modules
- - - - >8 - - - -
$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a "#", and everything on the line after them are ignored.
ide-cd ignore='hda hdc'
ide-detect
sd_mod
ide-scsi
- - - - >8 - - - -
Which I think should work. However, after reboot, the result is not what I
expected:
- - - - >8 - - - -
$ cdrdao scanbus
Cdrdao version 1.1.9 - (C) Andreas Mueller <andreas@daneb.de>
SCSI interface library - (C) Joerg Schilling
Paranoia DAE library - (C) Monty
Check http://cdrdao.sourceforge.net/drives.html#dt for current driver tables.
Using libscg version 'schily-0.8'
2,0,0 : SONY , CD-RW CRX195E1 , ZYS5
qd=": ERROR: unknow subsystem (scd0) in (/dev/sr0)
ATAPI:0,0,0 HL-DT-ST, CD-RW GCE-8526B , 1.03
ATAPI:0,1,0 Toshiba , DVD-ROM SD-M1712, 1808
- - - - >8 - - - -
I.e., my hdc is not ide-scsi but ide-cd.
However, if I load modules manually from command line, I get what I want:
- - - - >8 - - - -
% rmmod ide-cd ide-scsi; modprobe ide-cd ignore='hda hdc'; modprobe
ide-scsi
$ cdrdao scanbus

- - - - >8 - - - -
This is very strange!
BTW, looking at the dmesg output, I can see that hda & hdc have been
successfully ignored by ide-cd:
- - - - >8 - - - -
% dmesg | grep hd
SCSI device sda: 398297088 512-byte hdwr sectors (203928 MB)
hda: SONY CD-RW CRX195E1, ATAPI CD/DVD-ROM drive
hdc: HL-DT-ST GCE-8526B, ATAPI CD/DVD-ROM drive
hdd: Toshiba DVD-ROM DSM-1712, ATAPI CD/DVD-ROM drive
ide-cd: ignoring drive hda
hdc: attached ide-cdrom driver.

- - - - >8 - - - -
How is it happening? What is the fix? Thanks
Sorry the post is a bit long. But hope I've covered all that should be
covered.
