A known limitation? Anything specific I need to set up? =46rom ata-raid.c::ata_raid_intel_read_meta() /* * update our knowledge about the array config based on =20 generation * we only grap the first volume description (yet) since the * BIOS'n I have access to puts crap into the following ones */ There's your explanation :) When/If I get my hands on HW that supports this I'll add the support =20 to the ataraid driver.. BTW it knows how to deal with multiple RAID's on the same disks, but =20 no BIOS's I've had access to so far has allowed this yet... S=F8ren Schmidt sos@FreeBSD.org
