X-BeenThere: freebsd-scsi@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: SCSI subsystem List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 14 Apr 2004 10:41:50 -0000 Should the mpt driver support the disk mirroring present in some forms of the controller? It seems to be similar to the ata mirroring in some chipsets, it provides INT13 level access to the mirror for boot blocks, but once the OS is running expects the driver to know about the mirror. On an IBM x345 with this functionality I break any mirror as soon as I boot FreeBSD. Could this be worked round with any of the ata mirror tools? ----------------------------------------------------------------- Visit our Internet site at http://www.reuters.com Get closer to the financial markets with Reuters Messaging - for more information and to register, visit http://www.reuters.com/messaging Any views expressed in this message are those of the individual sender, except where the sender specifically states them to be the views of Reuters Ltd.
