installing cdwriter with ide-scsi
I am failing to make a new IDE CD-writer work on a good stable Debian
server and feel I'm out of ideas. Reading threads on this and other
lists and FAQs and HOWTOs, many dating back way before my kernel, is
taking further astray I think so a big plea for help. I've given as
much detail as I can below but I'm also happy for anyone who has got
this working with stable and 2.4.18 kernel to ignore what follows and
just lob in suggestions that I'll explore!
Thanks,
Chris
P.S. Here's the detail on the system:
Machine is K6 with a bunch of scsi and IDE drives of varying ages.
Version is woody up to date with major security upgrades etc. and
running kernel 2.4.18-1-k6. I've added:
append="hdc=ide-scsi"
and run /sbin/lilo and IDE channel 2 which was working fine with an
old IDE drive that I've dumped now has only the brand new AOPEN
cdwriter and finds it fine as kern.log shows:
Oct 25 18:50:04 www kernel: Kernel command line: auto
BOOT_IMAGE=Linux ro root=801 hdc=ide-scsi
Oct 25 18:50:04 www kernel: ide1: BM-DMA at 0xf008-0xf00f, BIOS
settings: hdc:pio, hdd:pio
Oct 25 18:50:04 www kernel: hdc: AOPEN 52X24X52 CD-RW 1.07
20030404, ATAPI CD/DVD-ROM drive
Oct 25 18:50:04 www kernel: ide-cd: ignoring drive hdc
I'm invoking ide-scsi with this in /etc/modutils:
# First (as per debian-user list traffic)
# get the ide-cd drive not to latch onto /dev/hdc
options ide-cd ignore=hdc
#
#
# set up an alias for /dev/scd0 to load sr_mod
alias scd1 sr_mod
#
#
# Now get ide-cd followed by ide-scsi loaded before the scsi drivers
pre-install sg modprobe ide-scsi
pre-install sr_mod modprobe ide-scsi
pre-install ide-scsi modprobe ide-cd
and I ran update-modules and lsmod now shows:

there.)
The old (defective) scsi-cdwriter still loads fine and reads CDs fine
but cdrecord can't see the ide one. cdrecord -scanbus shows only the
true scsi devices and cdrecord -v dev=ATAPI: -scanbus gives:
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg

cat /proc/scsi/scsi only shows the true SCSI devies
cat /proc/scsi/ide-scsi/1 (the only file there) shows only a standard
strapline (I guess):
SCSI host adapter emulation for IDE ATAPI devices
