Unable to detect SAS drives in T630 OS deployment.

I just bought the T630 and I'm having some issues detecting the hard disks when deploying the os. Any guidance would be greatly appreciated.

Hardware is as follows:

• Perch H730 Adapter
• Physical disks: x2 SAS 300GB; x3 SAS 500GB
• RAID Setup: RAID 1 (778GB x2) - Designated for my OS (Win 2008 R2)
• RAID 5 (465GB x3) - Designated for Data storage.

I'm booting in BIOS mode from bootable USB flash drive (which works as I've loaded the os on a test pc) and trying to do OS deployment from Lifecycle Controller.

Problem is after installer loads files I'm unable to see/detect the SAS disks in the RAID setup above.
I've broken the mirror and re configured my RAID virtual disks and initialized the drives (status: Online/Ready) but still unable to see them!

Do I need a driver for the Perch H730 controller in order for the windows installation to see the SAS drives? If so How do I deploy the drivers?

Please advise.
