Re: Cannot open SCSI driver
Hi!
In spite of a couple of suggestions, I am still trying to put my
cdwriter to work :(
First of all, make sure that the scsi support is loaded. The output for
the dmesg command is:
nostromo:/home/chiappa# dmesg |grep scsi
Kernel command line: auto BOOT_IMAGE=linux ro root=306 hdc=ide-scsi
hdd=ide-scsi max_scsi_luns=1
ide_setup: hdc=ide-scsi
ide_setup: hdd=ide-scsi
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
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: 0x/56x cd/rw xa/form2 cdda tray
sr1: scsi3-mmc drive: 24x/32x writer cd/rw xa/form2 cdda tray
remember that my problem is this 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.
Now, after surfed google a little, I am wonder if I have a problem with
the /dev/sg0 device. The MAKEDEV manual says that /dev/sg* are used to
speak to scsi devices, so...
In a potato system, which runs cdrecord OK, I have the following output
to the command "cdrecord -scsnbus /dev/sg0"
dft:/home/chiappa# cdrecord -scanbus /dev/sg0
cdrecord: No tracks allowed with this option
cdrecord: Usage: cdrecord [options] track1...trackn
the command is wrong, but the output proves that cdrecord does interact
with the /dev/sg0 device in some way.
In my woody, kernel 2.4.18, system I get for the same command:
nostromo:/home/chiappa# cdrecord -scanbus /dev/sg0
cdrecord: No such device. Cannot open '/dev/sg0'.
cdrecord says that the device doesn exist... but actually, this device
does exist:
nostromo:/home/chiappa# ls -l /dev/sg0
crw------- 1 root root 21, 0 Jun 13 2001 /dev/sg0
So, I have two questions:
a) does cdrecord use the /dev/sg* devices?
b) why cdrecord can see this device in my system?
Thanks in advance for any help!
