4–28 Compaq StorageWorks HSG80 Array Controller ACS Version 8.5 Maintenance and Service Guide
■ Display the instance codes that identify and accompany significant events which do
not cause the controller to terminate operation.
■ Display the last-failure codes that identify and accompany failure events which cause
the controller to stop operating. Last-failure codes are sent to the host only after the
affected controller is restarted successfully.
■ 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,” page 4-31, for specific details on this
feature.
Displaying Failure Entries
The controller stores the 16 most recent last-failure reports as entries in its non-volatile
memory. The occurrence of any failure event terminates operation of the controller on
which it occurred.
NOTE: Memory system failures are reported via the last failure mechanism but can be
displayed separately.
Use the following steps 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
3. Show one or more of the entries with the following command:
SHOW event_type entry# FULL
where:
■ event-type is LAST_FAILURE or MEMORY_SYSTEM_FAILURE
■ entry# is ALL, MOST_RECENT, or 1 through 16
■ FULL displays additional information, such as the I960 stack and hardware
component register sets (for example, the memory controller, FX, host port, and
device ports, and so on).
4. Exit FMU with the following command:
EXIT
The following example shows a last-failure entry. The Informational Report—the lower
half of the entry—contains the last failure code, reporting component, and so forth that
can be translated with FMU to learn more about the event.
