How to Import a Foreign Configuration in the RAID Controller Using the System Setup Menu

When a RAID controller detects that the RAID configuration is inconsistent or not synchronized with the rest of the array, it is marked with a foreign configuration. This could often happen when the drive is moved to another machine, but it could also happen if the drive went offline. The drive could go offline when a failure occurs, while a failure is happening right now, or when an unexpected situation occurs in the firmware.

An administrator must first Check the Virtual and Physical Disk Status, then Import Foreign Configurations. Click the appropriate process for more information.

Check the Virtual and Physical Disk Status

2. Press the F2 key when prompted.
