So you >just create entries with lun 0, 1, 2, 3, 4, 5, 6. You can then mount them >all separately. Here are the lines from my SunOS kernel config: disk sr0 at scsibus0 target 6 lun 0 # CD-ROM device disk sr1 at scsibus0 target 6 lun 1 # CD-ROM device disk sr2 at scsibus0 target 6 lun 2 # CD-ROM device disk sr3 at scsibus0 target 6 lun 3 # CD-ROM device disk sr4 at scsibus0 target 6 lun 4 # CD-ROM device disk sr5 at scsibus0 target 6 lun 5 # CD-ROM device Looking at the Freebsd man pages, scsi(4), I see that something almost identical is possible: device ch1 at scbus0 target 4 unit 0 Presumably you can use cd0 or cd1 above as well. Both scsi(4) and ch(4) refer to a special CDROM changer driver included within FreeBSD. However looking through the source, the best I can acertain, this ch(4) driver does not seem appropriate for the DRM602X which switches disks by SCSI LUN rather than by special SCSI command. In any case the above kernel config lines should work and allow you to mount all 6 disks.
