12. FRU Data
12.1 Structure and Functionality
The Management Controller provides 4 kB non-volatile storage space for FRU information.
Please refer to Related Publications: IPMI- Platform Management FRU Information Storage
Definition v1.0, Document Revision 1.1 which defines the structure of FRU data.
Full low-level access to read or write a module's FRU Information is provided by regular IPMI
FRU Device commands. Care must be taken when writing FRU information directly using stan-
dard IPMI commands because there is no write protection. Invalid FRU information may disturb
a shelf management software which uses the FRU data.
To avoid this situation there is a Kontron Linux tool 'frum', which permits displaying and partial
modification of FRU data. For example, the 'frum' tool makes it easy to modify Product Info
Area fields like Product Version or Product Serial Number.
