I believe the correct order of operation is to do a "detach" on the channel before physically removing the disk, insert the new disk, then do "attach" on the same channel. "list" should be done afterwards to ensure the new disk shows up. If you want me to verify for certain, I have a test box built in the other room which has a SATA hot-swap backplane on it. I've also seen cases where the "attach" works, but upon doing "list", the old disk ID/string is still shown. In this case I had to do a "detach", remove the disk, insert the new disk, "reinit", then an "attach" for things to work. Finally, I've also seen the kernel panic or hard-lock after running "reinit", but this may have had something to do with Intel MatrixRAID. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
