Cannot open SCSI driver
Hello!
I am running woody and I have a cdrom and a cdwriter. I want to write
cds using the cdwriter reading from the cdrom. Both are ATAPI devices,
so I have compiled the kernel, 2.4.18, with the following options:
a) scsi generic support enabled
b) scsi cdrom support enabled
c) ATAPI cdrom support disabled
At boot time, the scsi support is started as we can see from the dmesg
output:
hda: ST320413A, ATA DISK drive
hdc: CREATIVE CD5233E, ATAPI CD/DVD-ROM drive
hdd: Hewlett-Packard CD-Writer Plus 9500b, ATAPI CD/DVD-ROM drive
SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: CREATIVE Model: CD5233E Rev: 2.02
Type: CD-ROM ANSI SCSI revision: 02
Vendor: HP Model: CD-Writer+ 9500b Rev: 1.06
Type: CD-ROM ANSI SCSI revision: 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
Attached scsi CD-ROM sr1 at scsi0, channel 0, id 1, lun 0
sr0: scsi3-mmc drive: 8x/56x cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.12
sr1: scsi3-mmc drive: 31x/32x writer cd/rw xa/form2 cdda tray
So, I have the following scsi map:
adapter device channel id lun
CD5233E CD-ROM scsi0 sr0 0 0 0
HP CD-Writer scsi0 sr1 0 1 0
In the lilo.conf file I have the line
append = "hdc=ide-scsi hdd=ide-scsi max_scsi_luns=1"
Apparently everything works fine, I can listen music with the cdrom and
edit and copy files from the cdrom and cdwriter to the hd.
But when I run cdrecord with the -scanbus option I get the message:
nostromo:/home/chiappa# cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling
cdrecord: No such file or directory. Cannot open SCSI driver.
thus, cdrecord cannot find the SCSI driver (scsi0?). But the scsi drive
is readed during the boot process, as can be seen from the dmesg output
above.
What is going wrong? Any help will be very appreciated!
