X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 06 Jul 2005 10:49:20 -0000 A couple of months ago, I decided to take a chance and went SATA for one of our servers ... all others in the past have always been SCSI ... now, all of a sudden, the SATA server is *hanging* ... using tw_cli to look at the controller, and the drives and controller all appear to be well ... fsck finds the file systems to be good ... but after a period of time (an hour, maybe two) of running, the server grinds to a halt, and I have to get it rebooted and start all over again ... The server is an Intel SE7520 motherboard, with a 3Ware 9500S-4LP controller, and 3 ~126G hard drives ... operating system is RELENG_4 from ~May 22nd ... And none of the log files that I can think to look at are reporting any problems or errors :( So ... what causes an SATA system to 'hang'? If it was a SCSI system, it feels like the same thing that woudl be attributed to a bad cable or termination ... ---- Marc G.
