FRU Codes
The FRU codes indicate which disk array component is responsible for the log entry. Log
entries that do not involve disk modules typically require you to interpret the FRU Code
and the FRU Code Qualifier values to determine which component is identified.
To simplify reporting events, components within the disk array have been placed in FRU
groups. The FRU Code indicates which FRU group the component is a member of. The
FRU Code Qualifier further identifies the specific component within the group, and the
component’s status.
