With Redhat 9 and earlier, when I simply ran (as root) "cdrecord -scanbus" I would get a listing of the all the active devices on the SCSI bus. On my computer (with RH9) it looks something like this (I would have to reinstall RH9 to tell you exactly):
[root@orion]# cdrecord -scanbus
scsibus0:
0,0,0 0) *
0,1,0 1) *
0,2,0 2) 'IBM ' 'DDYS-T18350N ' 'S96H' Disk
0,3,0 3) 'NEC ' 'CD-ROM DRIVE:466' '1.26' Removable CD-ROM
0,4,0 4) 'HP ' 'CD-Writer+ 9200 ' '1.0c' Removable CD-ROM
0,5,0 5) *
0,6,0 6) *
0,7,0 7) *(Hopefully the E-mail won't screw up the formatting of the above) My best guess is that when they altered cdrecord to change it from the dev=0,4,0 format to the dev=/dev/scd0 format, they lost the scanbus functionality. As you'll see below, with Core 2 you can scan for a particular device IF you know what that device is, but the whole point of scanbus is that it scanned ALL SCSI devices (and multiple SCSI busses if you got 'em) and let you know what's out there and working. If anyone can confirm or deny these changes to cdrecord please let me know. Likewise, if you know of any syntax changes to cdrecord that will allow it to perform a scanbus as it did with RH9 I would appreciate it.
TIA
Here are four examples that I ran with Fedora Core 2. ------------------------------------------------------------------------------------------

I love where it says "For possible targets try 'cdrecord -scanbus'" when that's exactly the command I ran :).
