To edit the BMC FRU in the event of corruption, errors or changes you can use ipmitool which is available for all LNX OS and for Windows using ipmitool.exe .
In order to edit the FRU you need to know the field type, of which you can follow the chart below:
As an example, to change the Product Manufacture from "MiTAC" to another like "AI Storage", you would do the following:
ipmitool fru edit 0 P 0 "AI Storage"
The output should be similar to what is below and depending on what you enter into the field the FRU size will have to be adjusted but ipmitool will handle it automatically as shown below:
Afterwards you can check to see if the changes took affect by pulling the FRU using:
ipmitool fru print 0
