Public bug reported:
Hi
I have 2 Optiarc DVD Drives (DVD RW AD-7280S) connected to a SiI 3114
controller. At boot they both show op. When running Mint (Nadia), I can access
them as /dev/sr0 and /dev/sr1 respectively.
But the second drive has no symlinks
cd /dev
ll | grep 'sr[01]'
yields only
cdrom -> sr0 cdrw -> sr0 dvd -> sr0 and dvdrw -> sr0
sr0 sr1
cd disk/by-id/
ll | grep 'sr[01]'
yields
ata-Optiarc_DVD_RW_AD-7280S -> ../../sr0
cd disk/by-path/
ll | grep 'sr[01]'
yields
pci-0000:05:00.0-scsi-0:0:0:0 -> ../../sr0
When I connect one DVD drive to a different SATA controller, this changes to
(nearly) what one expects.
cd /dev
ll | grep 'sr[01]'
yields
cdrom -> sr0 cdrw -> sr0 dvd -> sr0 and dvdrw -> sr0
cdrom1 -> sr1 cdrw1 -> sr1 dvd1 -> sr1 and dvdrw1 -> sr1
sr0 sr1
cd disk/by-id/
ll | grep 'sr[01]'
still yields only
ata-Optiarc_DVD_RW_AD-7280S -> ../../sr0
cd disk/by-path/
ll | grep 'sr[01]'
yields
pci-0000:05:00.0-scsi-0:0:0:0 -> ../../sr0
pci-0000:04:05.0-scsi-0:0:0:0 -> ../../sr1
Obviously the 2 DVD drives interfere with each other, when on the same
controller.
Is this caused by
1. ata-Optiarc_DVD_RW_AD-7280S not having something unique (a serialnr) in its
name? Like in SAMSUNG_HD103SJS246JD1B2050
a. would this mean a bug in the (udev?) naming scheme?
2. or is the SiI 3114 controller the culprit?
I'm running Mint on top of Ubuntu quantal
