firwire cdrw. How do I mount it

john36 · Posted: Sat Nov 09, 2002 3:13 pm Post subject: firwire cdrw. How do I mount it

I have a firwire dvd/cdrw drive.

I can get the system to see it

after insmod sbp2, dmesg shows the following:

ieee1394: sbp2: Node 1:1023: Max speed [S400] - Max payload [2048]
scsi0 : IEEE-1394 SBP-2 protocol driver
Vendor: HL-DT-ST Model: RW/DVD GCC-4240N Rev: D110
Type: CD-ROM ANSI SCSI revision: 02

So, I would like to mount it but I don't know what /dev to use.

I do not have anything listed under /dev/scd

Do I have to run mknod?

I got this script from http://www.linux1394.org/
called rescan-scsi-bus.sh

it produces the following output:

Host adapter 0 (sbp2) found.
Scanning for device 0 0 0 0 ...
OLD: Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: HL-DT-ST Model: RW/DVD GCC-4240N Rev: D110
Type: CD-ROM ANSI SCSI revision: 02
0 new device(s) found.
0 device(s) removed.

So, what next?

What do you see under /dev/cdroms/ ? If you have devfs built into your kernel it should automatically make links to the appropriate files. If not, you'll have to look under /dev/scsi/host?/bus?/target?/lun?/cd for the appropriate device. Those '?'s are probably all zeroes if you don't have any other scsi devices.

Well, that's the problem.

I have nothing under /dev/cdroms

I have devfs..
One of my log messages is:

Mounted devfs on /dev

Under /dev/scsi the only thing listed is host0
under /dev/scsi/host0
the only thing listed is bus0

etc, etc until

/dev/scsi/host0/bus0/target0/lun0
which appears to be empty

Did you build scsi support and scsi cdrom support in your kernel? If you want to burn cds I believe you need to add in scsi generic support as well.
This thread is about setting up IDE cdrw drives but I believe since the firewire interface emulates a scsi interface for cdroms much of the information still applies.

Ok, hold everything. I have some serious problems with my kernel.

Some of the scsi modules compile OK, but when I try to load them I get a bunch of unsesolved reference errors. (sd_mod, and I think sr_mod, too, but I dont really remember right now. sg lives happily with insmod)

If I make them part of the kernel then insmod spb2 gets hung on initialization and I have to reboot the machine (or it locks up).

Finally, it's a single processor machine, but I cannot get the kernel to compile at all unless I tick smp in the .config file.

Wow a lot of weird stuff going on that I need to fix before I get to the cd drive issue.

I may try installing 1.2 instead of 1.4rc1.

As Arnold said, I'll be back.

It's a Dell Latitude X200 with a dvd/cdrw . Trying to run 2.4.18 vanilla, xfree4.2.0. on gentoo 1.4rc1 Most things work, but it still needs some fixing as this thread amply demonstrates.
