getting cdrom into ide-scsi

getting cdrom into ide-scsi

[Paulo Jorge O. C. Matos]

Hi all,

To record a cd I need to put my cdrom writer in ide-scsi so that's what 
I did. cdwriter is /dev/hdb, normal cdrom is /dev/hdd. I did:
image = /vmlinuz-2.4.17
   root = /dev/hda2
   label = Linux-2.4.17
   read-only
   append="hdb=ide-scsi"

But then I needed to duplicate a cd so normal cdrom also needs ide-scsi so:
image = /vmlinuz-2.4.17
   root = /dev/hda2
   label = Linux-2.4.17
   read-only
   append="hdb=ide-scsi, hdd=ide-scsi"

But now hdb no longer appears in cdrecord -scanbus, only hdd shows up. 
hdb is not! How can I put both?
And then, what's the device I should listen to, for listening audio 
cd's. /dev/cdrom and /dev/cdrom1 that are pointing to /dev/hdb and 
/dev/hdd respectively are no longer working!

Paulo, probably the /dev/hd* devices are redirected to /dev/sr[0123...].
Do a dmesg command and watch for that devices. What do you see?

hi,

I've got the same kind of configuration as you.
The devices show up as /dev/sr0 and /dev/sr1 (if you don't forget
to compile the sr_mod module, as I first did ;).
You simply should'nt use a comma between kernel parameters, 
in the "append" line.
My lilo.conf append line looks like this:
 append="hdc=ide-scsi hdd=ide-scsi"
Modify this line, run lilo, reboot and tell us if it really was 
the problem ;)

Xavier.

You're just about right. Everything is working great now. Thanks a lot!

SCSI CD-ROM devices may be called either "scd*" (e.g. "/dev/scd0") or
"sr*" (e.g. "/dev/sr0"); this is the name to which the /dev/cdrom
symlink should point, e.g.

	$ ls -l /dev/cdrom
	lrwxrwxrwx    1 glynn    root            4 Apr  2  2002 /dev/cdrom -> scd0


These devices are used for reading from the CD, and behave identically
to IDE CD-ROM devices. Regardless of the name, the device will be a
block device with major number 11, e.g.

	$ ls -l /dev/scd0
	brw-------    1 glynn    disk      11,   0 May  5  1998 /dev/scd0

CD writing is handled by a separated SCSI "generic" device, e.g. 
/dev/sg0; however, most software seems to use bus/target/LUN
addresses, so you seldom need to refer to the generic device.
