For better diagnostics, use the camcontrol utility, options reset, rescan, devlist and inquiry, after the system successfully booted. There should be a listing containing the tape drive and therefore the device node in /dev, or a more descriptive error message if something is wrong. % camcontrol devlist <SCANNER 2.02> at scbus0 target 6 lun 0 (pass0) <HL-DT-ST DVD-RAM GSA-H58N 1.01> at scbus2 target 0 lun 0 (cd0,pass1) This example shows a SCSI scanner at 0:6:0, the controller is an Adaptec 2940 SCSI adapter (PCI), driver is ahc0, as real SCSI hardware. If you're using the ATAPICAM facility, don't get confused with the ATAPI devices being on that list too. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
