I thought the different devices controlled what level of hardware compression was being involved. /dev/st0 would be none or default /dev/st0l would be level 1 /dev/st0m would be level 2 /dev/st0a would be level 3 Or something like that. Driver has to support it and all that. Looks like I was wrong. It seems to me that the different devices was one way of controlling hardware compression under AIX, but I could be wrong. I need to be able to find out what settings my tape drive has and then be able to change them :). I know how to do that in AIX, but that doesn't help me here. Turns out that there is a closed source util from the drive manufacturer. It isn't working right for me and I'd prefer to have a generic solution regarding tape drives in general. danke, der.hans -- # der.hans@LuftHans.com home.pages.de/~lufthans/ www.Opnix.com # Help Jerry Lewis stamp out M$...oops that's MDA - der.hans
