at the moment i have to setup an dg/ux server ( R4.20MU06 ) it works fine . i have attached a tape device ( wagntek ) and /dev/rmt/0 ( 0n ... ) is created.
i want to make a systemtape from the system with the systemtape util. on the shell i typed :
How long do you wait? Those tape drives can be slow... More likely though is that it is a bad tape. Can you try creating a new copy with a brand-new (never used) tape? You may also want to try running a cleaning tape through your drive if you haven't done so recently.
