Appendix C RAID Controller Considerations
Restoring RAID Configuration After Replacing a RAID Controller
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. To restore your RAID configuration to your new RAID controller, follow these steps.
Step 1 Replace your RAID controller. See Replacing a PCIe Card in a Motherboard Slot, page
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 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 6.
Step 4 Press F when you see the following onscreen 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 5 Press any key (other than C) to continue when you see the following onscreen 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. | |
Step 6 Watch the subsequent screens for confirmation that your RAID configuration was imported correctly:
•If you see the following message, your configuration was successfully imported. The LSI virtual drive is also listed among the storage devices.
N Virtual Drive(s) found on host adapter.
•If you see the following message, your configuration was not imported. This problem can occur if you do not press F quickly enough when prompted. In this case, reboot the server and try the import operation again when you are prompted to press F.
0 Virtual Drive(s) found on host adapter.
For More Information
The LSI utilities have help documentation for more information about using the utilities.
For basic information about RAID and for using the utilities for the RAID controller cards, see the Cisco UCS Servers RAID Guide.
