What the messages are basically saying is that your drives are not completing certain commands that we have issued to them. There were certainly some issues with certain DDYS drive firmware versions that could cause these types of symptoms. One thing that might help you is to lower the tag depth to your drives using the camcontrol utility. Can you also post the drive information from an invocation of "dmesg" on this system? -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
