Then select the ACU (array configuration utility).<BR /><BR />You create a so-called disk drive array first - that is just a 'collection of disks'. Choose the disks you intend to mirror. Then put a so-called logical disk into that disk array and select the desired RAID-level.<BR /><BR />Repeat it with 3 disks and create a RAID-5 logical disks.<BR /><BR />It looks a bit complicate to create a disk drive array first, but this is a 'feature', because you can put multiple logical disks with different RAID-levels onto a single set of disk drives.
