I didn't pay too much attention then since i initially thought that particular disk wasn't quite OK together with my new controller (the Tekram BIOS also has problems if the drive isn't spun-up at boot time). But now that i've seen the same kind of behaviour for other devices (like a scanner that has been power-cycled), i see the correlation to the CAM error handling changes here as well. If you don't get a reply here, please repost to freebsd-scsi@freebsd.org. If you look into the archives of that list, you can see some other discussions about the new error handling. Note that it's most likely not the rewritten error handling itself, but rather that the rewrite uncovered bugs in the top-layer SCSI drivers. > Only way to start disk again is reboot. Disconnecting (or powering off the drive), "camcontrol rescan", reconnect, "camcontrol rescan" would probably work as well. -- cheers, J"org .-.-. --... ...-- -.. .
