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 server 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
