Appendix C RAID Controller Considerations
Embedded SATA RAID Controller
Enabling the Embedded RAID Controller in the BIOS
Note The default setting in the BIOS for the embedded controller is disabled.
When you enable this controller, both the primary (SATA) and secondary (sSATA) controllers are
enabled.
Enabling SATA Mode and Selecting Option ROM Mode
Step 1
Set the SATA mode for managing the two boot drives:
a. Boot the server and press F2 when prompted to enter the BIOS Setup utility.
b.
Choose the Advanced tab, and then choose LOM and PCIe Slots Configuration.
c. Select PCH SATA Mode and then choose one of the options from the dialog:
–
AHCI—Advanced host controller interface. You can manage the internal SSD boot drives by
using your operating system’s storage management feature.
– Disabled—The embedded RAID controller is disabled.
–
LSI SW RAID—In supported server versions, you can manage the internal SSD boot drives or
the front-facing drives by using the server’s embedded SATA RAID controller. For support by
server version, see
Support Matrix For Cisco UCS C240 M4 Server RAID Controllers,
page C-4 .
Note
Before you change from LSI SW RAID mode to AHCI mode, delete all the RAID volumes
configured in the connected physical drives.
d.
If you selected LSI SW RAID mode and you want to set the option ROM mode, continue with the
next step. If not, skip to
Step 3 .
Note
There is no option ROM mode in AHCI SATA mode.
Step 2
Optional: Set the SATA option ROM mode for the two boot drives (only with LSI SW RAID SATA
mode):
a. Choose the Advanced tab, and then choose LOM and PCIe Slots Configuration.
b.
Select PCH SATA OPROM Mode and then choose one of the options from the dialog:
– Enabled—You can boot from these boot drives. You can use the UEFI management interface or
the free-standing legacy management utility.
–
Disabled—You cannot boot from these boot drives.
– UEFI Only—Select this to enable booting but manage RAID only by using the UEFI version of
the LSI utility that is built into the server BIOS. See
Launching the LSI Embedded MegaRAID
Configuration Utilities, page C-14 .
–
Legacy Only—Select this enable booting but manage RAID only by using the free-standing
version of the LSI utility. See
Launching the LSI Embedded MegaRAID Configuration Utilities,
page C-14 .
Step 3 Press F10 to save your changes and exit the utility.
