Put simply no, you'll need to change the bios settings, disable the raid option in the bios and set it to something like AHCI. OMV does not support hardware raid out of the box, it will require a driver and the option enable hardware raid. But, doing that, if it works, OMV will see your drives as one and you have no way of monitoring the raid itself.
so i need to go into the bios and change from raid to ahci? and this will give omv the ability to control the raid card, or it just isnt possible with my current server?
