    Thanks to Ashish Tripathi, Tom Traina, Michael Acklin, and Alan Rollow for
    their responses. It looks like the culprit was 2 fold. First, I did not
    have the cabling right on the tape library itself and second, it looks like
    my tape drive can ONLY write to superDLT though I thought I read somewhere
    that DLT4's would work.

    Thanks again,

    Chris

    Ok, I can now execute mt commands after calling HP support and checking the
    cableing. Now when I execute the following command

            /sbin/vdump -0 -x8 -u -N -f /dev/ntape/tape1_d1 /

    I get the following

            vdump: can't open dev </dev/ntape/tape1_d1>; [13] Permission denied

    Any ideas?

    TIA,

    Chris

    Admins,

            I have an alpha 4100 running 5.1B pk 1. I have connected a MSL5026
    with one SuperDLT tape drive. I checked to see if I had a valid path to the
    tape drive and the changer which I have and I can control the changer via
    the media robot utility. However, I cannot execute a mt command or a vdump
    command. When I first executed a vdump I was getting permission denied
    error. However now when I do a vdump or a mt command it just hangs. Any
    Ideas? I will summarize.

    TIA,
