The following notes are from Erkki (thanks).

For HP-UX 10.X
--------------
The generic SCSI needs the sctl kernel driver, you can check the
presence with:
# lsdev -d sctl
the output should look like this,
    Character     Block       Driver          Class
      203          -1         sctl            ctl

If not found, you can use SAM(1m) to add sctl to the kernel drivers.
(NOTE, this needs a reboot of your system)

Then you need to add devicefiles in /dev/rscsi/
(this is the default directory for scsilib)
they are made like this:
# mknod /dev/rscsi/cXtYlZ c 203 0x0XYZ02
where X controler instance, usually 0 or 1 for workstations
      Y scsi target addr ie. 0-7
      Z scsi LUN usually 0

example for a C-class workstation,
with the CD-rom set to SCSI target 3:
# mknod /dev/rscsi/c1t3l0 c 203 0x013002

check the device files with lssf(1m)

Please read the cdda2wav docs about chmod and root access.

To identify your CD-rom see diskinfo(1m)
