I kinda hoped that someone would smack their forehead and say "€#%@&§!, I forgot that.." I've already enable the scsidebug, but the output was not clear, atleast not to me. One interesting thing I saw, was that I'd get a "Target Busy" when I did scsi -f /dev/rod0 -d 1.. I could not see anything in the debug-output that popped out and said "here is the error", which led me to suspect the ahc-driver, not the od. Can one debug the ahc-driver? -Terje -- ____________________________________________________________________________ Terje Thøgersen, IS Advisor | E-mail : terje.thogersen@hydro.com Norsk Hydro a.s, Hydro Finance | Tel : +47-2243 2100
