Setting up exabyte drive on linux - Linux Setup, Configuration & Administration

Installed SCSI controller + exabyte drive. Both are seen under the "Hardware browser" However, system says : [rootheron proc]# mt -f /dev/st0 setblk 0 /dev/st0: No such device or address Why ? Maybe it's mandatory to plug a terminator, (which I have *not* at hand for now) and maybe it can work as is now since everything looks configured...Any opinion ? Thanks Gaetan ------------------------------------------------------------- SYMBIOS SCSI controller (Chipset 53C875) card jcd5075 Red Hat 9.0 8505S exabyte drive "Exabyte EXB-85058SQANXR0" is seen as tape drive under the "hardware browser"....

    dmesg | grep st will tell you if the drive is recognized, maybe
    you don't have the support for scsi tapes, if so, try load the
    module (insmod st).

    I have :

    [rootheron gaetan]# /sbin/insmod st
    Using /lib/modules/2.4.20-6/kernel/drivers/scsi/st.o
    insmod: a module named st already exists

    Maybe something useful (seen in dmesg):

    Then your tape isn't recognized by the system, is recognized by the
    controller then the whole stuff is discarded. Check your termination.

    Termination, yes. I am pretty sure that is the reason, as you say.
    However, I am surprised to see that even as it is now, these components
    are recognized. Also, I wonder how my tape drive will be recognized;
    /dev/st0, I think. Thanks for your help.
