In my experiments with a WangDAT 1300 tape drive on my VAXStation 3100, I often seem to get into a status where the operating system thinks the tape is busy, and it isn't. At this point, sometimes I can abort the running image and DISMOUNT the drive. Sometimes I can't. Sometimes I end up deleting the process (don't ask why - I get desperate). In any case, the drive is then unusable. I have a program called DEALLOCDEVICE which will perform a DEALLOCATE request in kernel mode ast of the owner process. Needless to say, I tried this several times first. A reboot is the normal fix, but I have seen methods presented in these groups for resetting bits using ANALYZE/SYSTEM and various patching utilities. Usually, my application of these causes a system reboot anyway :-), but I am game to try. Can anyone send me a procedure that might work - either a program or steps using any available tools? I am tired of hitting this problem and not really knowing a solution.
