The system has the symptom described above.

Workaround

Manually set UEFI boot path under boot manager of UEFI menu.

Additional Information

GUID for UEFI boot patch is a unique ID associated with RAID volume and SAS card. After system board replacement, UEFI boot path GUID changes as the on-board SAS has changed and is different from the UEFI back setting file. Users need to manually set the UEFI OS boot path after system board replacement.
