Yes, but with such a wonderfully vague description of the hardware, what help we can give you will also be wonderfully limited. > Tape drives are represented in /dev by stX or nstX ... are there > other representation of a tape drive? > No. Those are the only possible devices that a normal tape drive could use. /dev/stX devices rewind automatically after every operation, and /dev/nstX devices do not.

What is the make/model of your Ultra320 controller? What is your GNU/Linux distribution? These are absolutely *essential* information if you want anyone to help troubleshoot. Some controllers (notably the SmartArray 5i controller used on HP Proliant servers), have special instructions to get tape drives attached to them working. You have to write 'engage scsi' to some special files in /proc to get any tape drives to work. -- Capitalism requires people to be quiet souls in the workplace and wild pagans at the cash register. http://stormwyrm.blogspot.com/ _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
