Appendix C RAID Controller Considerations

Disabling the Embedded RAID Controller in the BIOS

Data migration from SW RAID to HW RAID is not supported and could result in data loss. Migrations
Caution
from SW RAID to HW RAID are supported only before there is data on the drives, or the case in which
there are no drives in the server.
If you migrate from using this embedded controller to a RAID controller card, you must disable the
embedded controller in the BIOS (see caution above).
Use the following procedure to disable the LSI MegaSR drivers.
Boot the server and press F2 when prompted to enter the BIOS Setup utility.
Step 1
Select the Advanced tab, then South Bridge.
Step 2
Step 3 Set Onboard SCU Storage Support to Disabled.
Step 4 Press F10 to save your changes and exit the utility.

Launching the LSI Embedded RAID Configuration Utility

Launch the utility by pressing Ctrl+M when you see the prompt during system boot.
