Appendix C RAID Controller Considerations

Embedded MegaRAID Controller

Disabling the Embedded RAID Controller in the BIOS

Caution Data migration from SW RAID to HW RAID is not supported and could result in data loss. Migrations 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.

Step 1 Boot the server and press F2 when prompted to enter the BIOS Setup utility.

Step 2 Select the Advanced tab, then South Bridge.

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.

For more information about using the Embedded MegaRAID software to configure your disk arrays, see the LSI Embedded MegaRAID Software User Guide.
