Reference codes

Reference codes are diagnostic aids that help you determine the source of a hardware or operating
system problem. To use reference codes effectively, use them in conjunction with other service and
support procedures.
The IBM Flex System p260 Compute Node or IBM Flex System p460 Compute Node produces several
types of codes.
Progress codes: The power-on self-test (POST) generates eight-digit status codes that are known as
checkpoints or progress codes, which are recorded in the management-module event log. The checkpoints
indicate which compute node resource is initializing.
Error codes: The First Failure Data Capture (FFDC) error checkers capture fault data, which the service
processor then analyzes. For unrecoverable errors (UEs), for recoverable events that meet or exceed their
service thresholds, and for fatal system errors, an unrecoverable checkstop service event triggers the
service processor to analyze the error, log the system reference code (SRC), and turn on the system
attention LED.
The service processor logs the nine-word, eight-digit per word error code in the IBM Flex System
Enterprise Chassis management-module event log. Error codes are either system reference codes (SRCs) or
service request numbers (SRNs). A location code might also be included.
