I have a series 428 (Enterprise 1200) with two channels and 32MB RAM in a Tyan dual PPro 200MHz running 5.0-current. This is not a production machine, and the are no important data on the disks so I can experiment with it as I like. I've had all kinds of problems with it and the three Quantum Viking disks I have. It trurned out that i must disable SCSI command Queing on the disks in the AMI BIOS otherwise the controller stops working within a couple of minutes. This error is more reproducible using RAID0 than RAID1 or 5. I've also had big trouble with a SCA to Wide and narrow converter on one of the disks. My experience is that the NCR SCSI controllers (as on the AMI cards) are rather picky about bad SCSI cabling and termination, esp. when running Ulra Wide. > I'm really not using all that much disk throughput. > I'll have that iostat log the next time it keels over. I can make it fail regerdless of thruput, this is not the old controller wedged bug. I have just put i thru two make worlds (-j64) without any problems, two disks RAID0 one on each channel. First time with default parameters, second time with Write back, adaptive read, cachedIO. Tell me if you want me to do something special with it to test it. At present I can only run it with two disks as I only have two reliable hotswap cradles, I have access to three more disks but I must buy more cradles before I can use them. /Martin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
