The Universal Unique Identifier (UUID) must be updated when the system board is
replaced. Use the Advanced Settings Utility to update the UUID in the UEFI-based
server. The ASU is an online tool that supports several operating systems. Make
sure that you download the version for your operating system. You can download
the ASU from the IBM Web site. To download the ASU and update the UUID,
