I donno if fedora has a modules.autoload functionality or not,  so you can
either tell it to do this there or put the following lines in
/etc/rc.d/rc.local

modprobe sr_mod
modprobe cdrom
modprobe sg

Odds are those modules aren't loading by default hence no CDrom's are seen on
the SCSI bus..

running "cdrecord -scanbus" will usually show you if the drives are found... 
Try running that command BEFORE and AFTER the modprobe lines above to see if it
finds new things.  Also a simple "cat /proc/scsi/scsi" will show you what SCSI
devices are detected,  if only some show up,  check termination of the external
SCSI bus,  the bus is terminate ONLY at the ends,  don't enable termination on
each drive, as it makes things very unpredictable and drives on the bus tend to
disappear due to bus activity and loading..
