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 3-43.

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.
