I have a tape backup that I want to share with two systems, and I want them to be both connected at the same time. I have connected both controllers to the tape backup, made sure that they were configured as different device numbers, and re-booted both systems. One is a Windows Machine, the other is a BSD box. Both of the controllers are the same (Adaptec 29160N) The BSD box is complaining about seeing SCSI bus resets on the bus: ahc0: Someone reset channel A What is the correct way to do this (if it is at all possible)? Are there special kernel or hardware settings required for this to work properly? Thanks for your help. --- Damien Tougas Systems Administrator Carroll-Net, Inc. http://www.carroll.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
