I am trying to write a CD and I have atapiscsi0 at pciide0 channel 1 drive 0 scsibus0 at atapiscsi0: 2 targets cd0 at scsibus0 targ 0 lun 0: <SAMSUNG, CDRW/DVD SN-324S, U303> SCSI0 5/cdrom removable
man cdrecord says: "Some operating systems or SCSI transport implementations may require to specify a filename in addition. In this case the correct syntax for the device is: dev= devicename:scsibus,target,lun[...]" May OpenBSD require to specify a filename in addition? If OpenBSD requires a filename in addition, does cdrecord have any further requirements on the filename apart that it is somehow associated with the writer in question? As dmesg suggests, I have a filename /dev/cd0a and /dev/cd0c. However, cdrecord dev=help suggests another filename: Transport name: SCIOCCOMMAND Transport descr.: SCSI for devices known by *BSD Transp. layer ind.: Target specifier: device or bus,target,lun Target example: /dev/rcd0a:@ or 1,2,0 SCSI Bus scanning: not supported Open via UNIX device: supported In this case it's filename /dev/rcd0a, which I have on my system, too. So the possible values for dev= according to this "documentation" are so far dev=0,0,0 dev=/dev/cd0a:0,0,0 dev=/dev/cd0c:0,0,0 dev=/dev/rcd0a:0,0,0 $ cdrecord dev=0,0,0 disk1.iso cdrecord: No write mode specified. cdrecord: Asuming -tao mode. cdrecord: Future versions of cdrecord may have different drive dependent defaults. cdrecord: Continuing in 5 seconds...
