Restoring RAID Configuration After Replacing a RAID Controller
Cisco UCS C460 Server Cabling
The cable connections required for each type of supported controller are as follows:
LSI MegaRAID SAS 9240-8i PCIe Card
This controller can control a maximum of 8 internal drives. The required two SAS cables are included
with the server. Cable 1 controls drives 1–4 and cable
2 controls drives 5–8.
1. Connect SAS cable 1 from connector SAS1 on the controller to the SAS1 connector on the
backplane.
2. Connect SAS cable 2 from connector SAS2 on the controller to the SAS2 connector on the
backplane.
LSI MegaRAID SAS 9260-8i PCIe Card
This controller can control a maximum of 12 internal drives. The required two SAS cables are included
with the server. Cable 1 controls drives 1–6 and cable
2 controls drives 7–12.
1. Connect SAS cable 1 from connector SAS1 on the controller to the SAS1 connector on the
backplane.
2. Connect SAS cable 2 from connector SAS2 on the controller to the SAS2 connector on the
backplane.
Restoring RAID Configuration After Replacing a RAID Controller
When you replace a RAID controller, the RAID configuration that is stored in the controller is lost. Use
the following procedure to restore your RAID configuration to your new RAID controller.
Step 1 Replace your RAID controller. See Replacing a SAS Riser (RAID Controller), page 3-16.
Step 2 If this was a full chassis swap, replace all drives into the drive bays, in the same order that they were
installed in the old chassis.
Step 3 If Quiet Boot is enabled, disable it in the system BIOS.
Step 4 Reboot the server and watch for the prompt to press F.
Note For newer RAID controllers, you are not prompted to press F. Instead, the RAID configuration is
imported automatically. In this case, skip to Step 7.
Step 5 Press F when you see the following on-screen prompt:
Foreign configuration(s) found on adapter.
Press any key to continue or ‘C’ load the configuration utility,
or ‘F’ to import foreign configuration(s) and continue.
Step 6 Press any key (other than C) to continue when you see the following on-screen prompt:
All of the disks from your previous configuration are gone. If this is
an unexpected message, then please power of your system and check your cables
to ensure all disks are present.
Press any key to continue, or ‘C’ to load the configuration utility.
