[dm-devel] Mixed Mode Raid!

[Dieter Zuleger]

Hi,
Silicon Image´s Raid-Controller like the 3132 or 3114 support a certain mixed-mode raid, like
Intels matrix raid of the ich6 oer ich7. For example, I use two Maxtor 6V300F0 on a Silicon Image 3132 pcie-raid-card. With Silicons sataraid5-tool within windows xp I created on the first 160Gb of each disk a raid0-array and on the remaining 120Gb of each disk a raid1-array. I can use it with windows but dmraid-1.0.0.rc9 discovers only the first raid array.
dmraid -s -vvv

I think its a nice feature. Any clues to make it discover?
