Here is an excerpt from /usr/doc/howto/CDROM-HOWTO.gz :

  4.3.12.  SCSI Driver
         
         Principal author: David Giller
    Multi-session support: yes (depending on drive)
   Multiple drive support: yes
  Loadable module support: yes
     Reading audio frames: no 
             Auto-probing: yes
              Device file: /dev/scd0, major 11
       Configuration file: cdrom.h
     Kernel config option: SCSI CDROM support?
              README file: none

  There are kernel command line option specific to each type of SCSI
  controller. See the SCSI HOWTO for more information.

  Multiple drives are supported (up to the limit of the maximum number 
  of devices on the SCSI bus). Create device files with major number 11
  and minor numbers starting at zero:

       # mknod /dev/scd0 b 11 0
       # mknod /dev/scd1 b 11 1

  While the kernel driver itself does not support reading digital audio
  frames, some SCSI drives have the capability and will work with the
  cdda2wav program (which uses the generic SCSI kernel interface).

mknod /dev/scd2 b 11 2
mknod /dev/scd3 b 11 3
mknod /dev/scd4 b 11 4
mknod /dev/scd5 b 11 5
mknod /dev/scd6 b 11 6
mknod /dev/scd7 b 11 7
mknod /dev/scd8 b 11 8
