Fault Management Utility (FMU)
FMU provides a limited interface to the controller fault management software.
Use FMU to:
■ Display the last failure and memory-system failure entries that the fault
management software stores in the controller nonvolatile memory.
■ Translate many of the code values contained in event messages (for example,
entries might contain code values that indicate the cause of the event, the
software component that reported the event, or the repair action).
■ Display the Instance Codes that identify and accompany significant events
that do not cause the controller to halt operation.
■ Display the Last Failure Codes that identify and accompany failure events
that cause the controller to halt operations. Last Failure Codes are sent to the
host only after the affected controller is restarted.
■ Control the display characteristics of significant events and failures that the
fault management system displays on the maintenance terminal. See
“Controlling the display of significant events and failures” on page 71 for
specific details on this feature.
■ Display device services event silo.
■ Display detailed device characteristics.
Displaying last failure entries
The controller stores the 16 most recent last failure reports as entries in its
nonvolatile memory. The occurrence of any failure event halts operation of the
controller on which it occurred.
Note: Memory system failures are reported through the last failure mechanism but
can be displayed separately.
To display the last failure entries:
1. Connect a PC or a local terminal to the controller maintenance port.
2. Start FMU with the following command:
RUN FMU
