You have to setup the RAID-1 volume in the LSI BIOS. The normal motherboard BIOS is supposed to execute the bootrom in the LSI card, which will allow you to enter the LSI BIOS. If I remember correctly it's "control-C" on bootup, instead of "DEL". Then you select new IM volume (Integrated mirroring)=20 You can migrate your main disk to the volume, and your second disk will then be synchronized to look like the first disk.

If you get time and want to do me a favor, configure 2 drives on the controller in a RAID-1 configuration. Then do a disk test on the RAID-1 volume, say with iozone or any other method, and tell me your performance. I get slow RAID-1 performance, still cannot figure this out, ~5 Mbytse/sec instead of ~ 30 Mbytes/sec with no volume. With NCQ enabled it goes up to 15, but it' still not 30. I can get faster RAID-1 performance by implementing this in software doing parallel writes. Johan -----Original Message----- How I can test it... First of all FreeBSD should see RAID, but it only see separated HDD (da*) This is the problem that I described _______________________________________________ freebsd-scsi@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-scsi To unsubscribe, send any mail to "freebsd-scsi-unsubscribe@freebsd.org"
