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,
