I am running RH 7.0 and have added a Yamaha 2100EZ CD writer (IDE). I used the
SxS for replacing a cdrom with a cdburner as the blueprint for adding the
writer.
I have no SCSI controllers. Before I added the writer I had the following
drives:
/dev/hda boot partitions for RH and LTP
/dev/hdb partitions for COL2.4 boot and home directories
/dev/hdc CD-ROM
I added the following line to my lilo.conf, then ran lilo:
append="hdd=ide-scsi"
I wanted /dev/hdd to be used for the CD-RW. I performed the following to try
and make this happen (as root of course):
$ mknod /dev/sr0 b 11 0
$ mkdir /mnt/cdrw
$ ln -s /dev/sr0 /dev/cdrw
Added the following line to /etc/fstab
/dev/cdrw /mnt/cdrw iso9660 noauto,owner,ro 0 0
Created /etc/rc.modules as follows (there wasn't one initially):
#!/bin/sh
/sbin/modprobe sg
/sbin/modprobe ide-scsi
At this point (after rebooting), when I tried mounting the CD-RW I got the
following:
$ mount /dev/cdrw /mnt/cdrw
mount: the kernel does not recognize /dev/cdrw as a block device
then I tried:
$ mount /dev/sr0 /mnt/cdrw
mount: the kernel does not recognize /dev/csr0 as a block device
And I could no longer access my CD-ROM. The CD-ROM should not be using the
SCSI emulation as /dev/cdrom->/dev/hdc. This is very puzzling to me.
So, I put both CD-ROM and the CD-RW pointing to the SCSI devices by dong the
follwing:
$ mknod /dev/sr1 b 11 0
$ rm /dev/cdrw; ln -s /dev/sr1 /dev/cdrw
$ rm /dev/cdrom; ln -s /dev/sr0 /dev/cdrom
Now I have the following configuration:
/dev/hda boot partitions for RH and LTP
/dev/hdb partitions for COL2.4 boot and home directories
/dev/sr0 CD-ROM
/dev/sr1 CD-RW
With this configuration, it appears that when I mount sr0, then mount sr1, I
can only see the content of sr1 (and visa versa, depending on mount order).
Also, I cannot read from the CD-RW from a CD player program or anything else.
I *can* read from the CD-ROM using a CD player program, however.
Is the ide-scsi emulator code not able to handle more than 1 device (I don't
think this is the case)?
I can also use xcdroast and xgcombust to burn CDs and read from the CD-ROM. So
I can still function. But this state puzzles me and I really want to
understand what is happening.
Any help would be appreciated.
TIA
