This must be a software RAID controller. It uses software in your OS to do the several RAID levels. The controller simply "acts" as a RAID controller and then passes the real job to the OS. > > Defining a RAID5 a bios level, starting the server and building up the = Raid at OS level: > And now I have a functional Raid named ar0. No you probably don't have a functional RAID5 setup. Please read the ataraid manual page. It says that RAID5 is not supported. [snip] > Any hints? You can use other RAID levels that are supported for your controller. You can also use gmirror or graid3. HTH, Nikos
