You're getting parity errors and cables, or termination are the likely cause of these errors. 2. Switch to using CAM. sd1 is returning busy status maybe because it is doing a thermal recal (who knows). The old SCSI layer doesn't have the facilities to deal with a busy device gracefully, we end up beating on the drive hoping it will accept the command and we probably confuse it to the point of not working. The CAM patches are available at ftp://ftp.FreeBSD.org/pub/FreeBSD/cam. See the README file at that location for more details. > Thanks, > david > -- > David Wolfskill UNIX System Administrator > dhw@whistle.com voice: (650) 577-7158 pager: (650) 371-4621 -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
