Got the 3Ware 7450's firmware upgraded. Swapped out the one maxtor disk that showed some errors, reran the smartctl -t long tests and made sure every disk succeeded. The box still randomly hangs and it looks strongly like it is I/O related. I wonder if my controller itself is bad. I am about ready to give up on this setup. Problem is swapping out the card means a new riser card, well at least in theory to handle the 64 bit / 66 mhz issue with risers that 3ware has. Or I can trust 3ware's tech support that all new cards are already fixed. Heh. Or we can watch as nothing else is fixed. Or maybe it's the interconnects, (cold swap ATA backplane) but I do not see how that should lead to a full fledged I/O hang error. twe0: <3ware Storage Controller driver ver. 1.40.01.002> port 0xc800-0xc80f mem 0xfe000000-0xfe7fffff,0xfeaffc00-0xfeaffc0f irq 2 at device 7.0 on pci1 twe0: 4 ports, Firmware FE7X 1.05.00.068, BIOS BE7X 1.08.00.048 - Carroll Kong ----- Original Message ----- From: "Carroll Kong" <me@carrollkong.com> To: "Anton Ivanov" <ai1@ipaccess.com>; <freebsd-stable@freebsd.org> Cc: "Jason Thomson" <jason.thomson@mintel.com> Sent: Monday, September 13, 2004 11:57 PM Subject: Re: 3ware 7506, FreeBSD 4.x, Maxtor Disks & SMART Problems. > One of the maxtor disks at the colocation with the 3ware card was failing to > complete it's long tests with read errors.
