I found a simmilar thread on this issue but and I corected a mistake I made in my kernel's config but my dvd drive is still not showing up as /dev/dvd.
The config is located at: http://dpaste.com/3PENA37
lspci output is located here: http://dpaste.com/25Z2TJ9
Thanks |

| udev creates the /dev/dvd symlink. Do you have it running correctly? |

...actually, udev has stopped doing that quite awhile ago. |

I think so.
How do I create it, just symlink? |

Here how I do :
| Code: |
$ cat /etc/udev/rules.d/99-cdrom_id.rules
# udevadm info --query=property --name=/dev/sr0
# udevadm control --reload-rules
# Optiarc_DVD_RW_AD-5200A
KERNEL=="sr0", ENV{ID_MODEL}=="Optiarc_DVD_RW_AD-5200A", SYMLINK+="cdrom2 cdrw2 dvd2 dvdrw2 dvd_noir"
|
You run first udevadm command to get the correct ID_MODEL value.
Second command to reload rules, and probably create the symlinks. |

Due to this thread I looked into my /etc/udev/rules.dir and into /dev. I found only ONE symlink (cdrom). The content of my "70-persistent-cd.rules" is:
# This file was automatically generated by the /lib64/udev/write_cd_rules
# program, run by the cd-aliases-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and set the $GENERATED variable.
# DVD-ROM_GDR8164B (pci-0000:03:00.1-scsi-0:0:0:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:0:0", SYMLINK+="cdrom", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:0:0", SYMLINK+="dvd", ENV{GENERATED}="1"
# DVDRAM_GSA-H10N (pci-0000:03:00.1-scsi-0:0:1:0)
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:1:0", SYMLINK+="cdrom1", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:1:0", SYMLINK+="cdrw1", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:1:0", SYMLINK+="dvd1", ENV{GENERATED}="1"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:03:00.1-scsi-0:0:1:0", SYMLINK+="dvdrw1", ENV{GENERATED}="1"
So, for me it looks like udev reads only the first line ... is it a bug or a feauture ... ?
(I have no eudev; my udev version is 216 (stable tree)) |

Your file seems really old, I think you could remove it since these rules are ignored.
The /dev/cdrom symlink you found is created by an udev rule into /lib/udev/rules.d/60-cdrom_id.rules. |

Your guess was right - but I have no 60-x-file (first installation of this pc was 2006). I have only these:
-rw-r--r-- 1 root root 972 10. Nov 2009 70-persistent-cd.rules
-rw-r--r-- 1 root root 421 8. Dez 2012 70-persistent-net.rules
-rw-r--r-- 1 root root 1820 8. Feb 2013 80-net-name-slot.rules
-rw-r--r-- 1 root root 1820 10. Sep 12:47 80-net-setup-link.rules
I will make no change - the system is running stable. |
