But CAM means current. Downgrading production servers to current is not an option. That is why I like the DPT driver for 2.2. The driver/card is quite robust, and I haven't seen it hang ever. I have nearly identical systems (differ only in the amount of RAM and number of disks), one with a DPT and one with a 3940UW. The 3940UW system will reboot complaining about ahc error, every 4 to 6 weeks. The DPT system has never had a problem. Too bad no one in core has imported the DPT driver into -stable yet. > >Tom > > -- > Justin Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
