The Promise Tx4310 has to be a HW raid controller - hopefully ;-)) But to get full access you have to have drivers to support this hardware. In the ata man pages the controller (chip is PDC40719) is mentioned to be supported. But not in the RAID5 mode - that´s my mistake. I just was realy irritated for after buliding up and even after rebooting without errors the device ar0 named itself RAID5 ... Maybe I used parts of new code which isn´t finished at all .... Thanxs Dietmar

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.
