Goal

After a motherboard replacement, the serial number is all zeros, or incorrectly matches the chassis.
For example:

-> show /SYS
/SYS
   Properties:
       type = Host System
       ipmi_name = /SYS
       product_name = SUN FIRE X4150
       product_part_number = 602-4252-01
       product_serial_number = 0000000000
       product_manufacturer = SUN MICROSYSTEMS
       power_state = On

Solution

Use the sdfru utility, which is available in the \utility\sdfru directory of the Tools and Driver release disc when booted into DOS.
You will need to shutdown your operating system, in order to boot from the Tools and Drivers CD/DVD (available in patch 11843046).
Once booted, you will see 3 options:
1. Run Hardware Diagnostics
2. Erase Primary Boot Hard Disk
3. Exit to DOS

Choose option 3 to exit to DOS

Then change directory to utility\sdfru and execute sdfru:

cd utility\sdfru
sdfru

Prompts and output will be similar but not identical to the following:

[Version_3.0.0] C:\UTILITY\SDFRU>sdfru -m3 -ssn 0807TST054
SDFru v1.11
System identified as Sun Fire X4150
Reading current FRU PROM contents...Done
Enter PPN: 602-4252-01      <<<<<<<<<<<<<<<<<<<< you can get this from show /SYS command on the ILOM
Setting System Serial Number to: 0807TST054
Setting Product Part Number to : 602-4252-01
Extra Segment Updated
Writing FRU prom... Done (System and SP restart is needed to take affect)

Here is the sdfru readme for syntax explanation:

-o <File> Output filename for some operations
-l Display the prom serial numbers and part numbers
-read Raw Read the FRU PROM and save to filename (no checking)
-extract Extract prom contents and prepare files for upload (may require doslfn.com)
-m1 Board Level Mode (don't accept system level info)
-m3 System Level Mode (don't accept board level info)
-vid XXXX Use <XXXX> as vendor ID
-hwrev RR Use value as Initial HW Rev Level
-ssn SSN Use value as SSN (accepts dashes or no dashes)
-ppn PPN Use value as 602 product part number (accepts dashes or no dashes)
-fsn FSN Use value as FRU serial number, otherwise use input file value
-mac ADDR Use value as the base MAC address of host port 0 (no colons)
-bmcmac ADDR Use value as the base MAC address of host port 0 (no colons)
-elom Use legacy ELOM interface (x4150, X4250 only)
