sdX is used for hard disks (scsi disk). A DVD is not a disk so it is
not listed there. It will probably be defined as sr0.

Anyway, the best way to find out is to install the tool lsscsi using
yum. Here is the example of the output from lsscsi on my laptop :

# lsscsi
[0:0:0:0]    disk    ATA      ST910021AS       4.06  /dev/sda
[4:0:0:0]    cd/dvd  HL-DT-ST DVDRAM GSA-4083N 1.08  /dev/sr0

So that should help you indentify your devices.

Hoping the problem magically goes away by ignoring it is the
"microsoft approach to programming" and should never be allowed.
