(mylex, PERC, etc) Message-ID: <20020517221728.V44320-100000@utility.clubscholarship.com> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I have a few systems running dell PERC raid controllers, and a few running mylex controllers. All of them are being used to provide RAID mirrors, which I use to run FreeBSD on. So the question is, what happens when I am happily running along, and a drive fails ? Certainly things keep running, since they are mirrors, but how do I know a drive has failed ? Does the driver report to syslog ? I would really hate to wake up someday and lose the second drive in a mirror volume, only to realize the first drive had died a month ago and I never knew about it. So how do I know when bad things happen with my RAID drives? thanks, pt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
