Hi all,
I got the "common" problem that my CD-Writer won't work. (debian sarge, heise
c't server kernel)
System is equipped with a SCSI-Controller(P2B-S Onboard Adaptec), the CD-Writer
is connected on the primary master IDE Bus. The BIOS detects the driver, and it
has worked as a normal ide-drive.
So I changed the common things:
Grub: menu.lst += hda=ide-scsi (tried also with hda=scsi)
under /etc/modutils I created a file named cdr and appended it to modules.conf
with update-modules. Content:
# Modules for the CD-Writer
options ide-cd ignore=hda
alias scd0 sr_mod
pre-install sg modprobe ide-scsi
pre-install sr_mod modprobe ide-scsi
pre-install ide-scsi modprobe ide-cd
alias block-major-11 sr_mod
alias char-major-21 sg
...so, at boot time I get a:
kernel: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
.......
kernel: scsi1 : SCSI host adapter emulation for IDE ATAPI devices
...but thats it.
cdrecord -scanbus only outputs the "real" SCSI devices, If I try with cdrecord
-prcap, I get the output:
scsidev: '1,5,0'
scsibus: 1 target: 5 lun: 0
Linux sg driver version: 3.1.25
cdrecord: No such file or directory. Cannot open '/dev/pg5'. Cannot open SCSI
driver.
...I have no /dev/pg* devices :( - and I also get this output if I don't add
anything of the modules/loader- addons.
If I try all this without the ide-scsi sh..., e.g.:cdrecord -dev=ATAPI:1,5,0
-scanbus ...I get
scsibus0:
0,0,0 0) 'LITE-ON ' 'LTR-16102B ' 'OS05' Removable CD-ROM
...which whon't work for writing:
SCSI buffer size: 64512
atapi: -1
cdrecord: Cannot do inquiry for CD/DVD-Recorder.
cdrecord: Input/output error. test unit ready: scsi sendcmd: fatal error
CDB: 00 00 00 00 00 00
Any hints appreciated!!!
Thanks in advance,
Chris
