The use of
ide-scsi on the IBM eServer xseries 450 (Model: 8688-5RX) has been known to cause problems with writing CD's. Problems may also exist when using it for reading as well. The
ide-scsi module is automatically loaded by the installer. Follow the steps below after installation to disable
ide-scsi and use the drive as a normal IDE/ATAPI device.
/etc/elilo.confand remove all instances of
hda=ide-scsi(depending on system configuration, it may be an ide device other than
Save this file and reboot the system.
/dev/cdrompoints to the IDE cdrom device from step 1, NOT
/dev/scd0. (This should automatically happen as a result of step 2)
The CD/DVD drive should now function normally as a reader.
Red Hat Enterprise Linux 3 supports writing of CD's through the ATAPI interface. To use
cdrecord with an ATAPI device, modify the command line arguments slightly.
Finding the location of your CD writer on the ATAPI bus:
cdrecord -dev=ATAPI --scanbus
The command line output should looks something like the following:
scsidev: 'ATAPI' devname: 'ATAPI' scsibus: -2 target: -2 lun: -2 Warning: Using ATA Packet interface.< Warning: The related libscg interface code is in pre alpha. Warning: There may be fatal problems. Using libscg version 'schily-0.7' scsibus0: 0,0,0 0) 'HL-DT-ST' 'RW/DVD GCC-4160N' Removable CD-ROM 0,1,0 1) * 0,2,0 2) * 0,3,0 3) * 0,4,0 4) * 0,5,0 5) * 0,6,0 6) * 0,7,0 7) *
Once the location of the CD writer on the ATAPI bus has been found
in this case 0,0,0it can be written to.
cdrecord to write a
.iso file to a blank CD-R/CD-RW use a command like the following:
cdrecord -dev=ATAPI:0,0,0 /path/to/cdimage.iso
ATAPI: in the
dev= statement tells cdrecord to use ATAPI bus rather than its default of SCSI.
