storage - Disabling RAID feature on HP Smart Array P400



I'm planning to use ZFS on my system (HP ML370 G5, Smart Array P400, 8 SAS disk). I want ZFS to manage all disks individually, so it can utilize better scheduling (i.e. I want to use software RAID feature in ZFS).



The problem is, I can't find a way to disable RAID feature on the RAID controller. Right now, the controller aggregates all of the disks into one big RAID-5 volume. So ZFS can't see individual disk.



Is there any way to acomplish this setup?


Answer



If you simply delete the volume in the RAID BIOS that exposes the disks directly in some versions of the SmartArray controllers. We always use the controller even with things like ZFS.
