I use > NVIDIA MediaShield on SUN X2100 M2 and it seems that all works: ata(4) and ataraid(4) will answer that; FreeBSD can not write the nVidia *meta*data to create or modify RAID sets with that kind of fake raid (nor does it support the "RAID 5" level in nv fakeraid). > ad4: 152627MB <Seagate ST3160827AS 3.42> at ata2-master SATA150 > ad6: 152627MB <Seagate ST3160827AS 3.42> at ata3-master SATA150 > ar0: 152627MB <nVidia MediaShield RAID1> status: READY > ar0: disk0 READY (master) using ad6 at ata3-master > ar0: disk1 READY (mirror) using ad4 at ata2-master That's fine; it reads the *meta*data and then handles the fakeraid setup normally. But to add an extra disk to the array you will have to go through the BIOS. -- KDE Quality Team http://www.englishbreakfastnetwork.org/ GPG: FEA2 A3FE http://people.fruitsalad.org/adridg/ "It is impossible to make an emphatic point with only two arms."
