I needed to set up an Intel box to replicate a Sun E450 fileserver with ten HDs, while my employer moves to a new office. I'm using an Abit KT7A-RAID MB + four identical WD1200JB's in a RAID-0+1 config via the HPT-370. The device is recognized as:
ar0: 228946MB <ATA RAID0+1 array> [29186/255/63] status: READY
1) Checking the handbook led me to atacontrol(4). However, "man 4 ar" doesn't seem relevant, nor could I find references to device ar0 in (or via) the ata(4) manpage. Is more documentation available on device ar0?
2) Does the Highpoint-370 mirror a 2-disk stripe, or does it stripe onto two mirrors? In other words, will it stay up in the face of (some) multiple disk failure scenarios?
atapci0: Correcting VIA config for southbridge data corruption bug
I'm familiar with the notion that there is some sort of PCI timing issue affecting large (100+ MB) IDE-to-IDE data transfers via DMA, and was often made worse if certain sound cards were present. Unfortunately, that sounds highly applicable to me. So what am I in for?
3) Does this message indicate that FreeBSD has a software workaround for the issue, or am I still taking a risk of data corruption? I've got a recent BIOS (kt77n?) w/ "HPT 370 RAID BIOS version 1.11.0402", if that matters.
Thanks, -Chuck
