I've added a DLT tape library to a system that already had a DLT tape drive. The problem: dmesg shows only one tape drive, the original. The tape library's tape drive is not showing up. $ sudo camcontrol devlist <DEC TL800 (C) DEC 0326> at scbus0 target 0 lun 0 (pass0,ch0) <QUANTUM DLT7000 1E48> at scbus1 target 5 lun 0 (sa0,pass1) <HL-DT-ST DVDRAM GSA-H10A JL02> at scbus3 target 0 lun 0 (pass2,cd0) I have tried a 'camcontrol rescan all' but I don't get the tape drive for the tape library (which I'm guessing with be sa1). The following shows the expected results for tape labels from within the tape library [dan@ngaio:~] $ sudo chio -f /dev/ch0 status -v Password: Sorry, try again.
