Issue
-
DIMM-1 was replaced due to the following panic error.

- Even after replacement the DIMM-1, the system's Fault LED remains lit.
- The "
service-event show" command indicates that DIMM-1 is still in an error state.

- Attempting to reseat or replace the DIMM again does not resolve the issue.
- Issue persists after implementing a Takeover/Giveback and BMC reboot.
