Utilities and Exercisers

The controller’s software includes the following utilities and exercisers to assist in troubleshooting and maintaining the controller and the other modules that support its operation. For more details on each of the utilities and exercisers, see the HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide.

Fault Management Utility

The Fault Management Utility (FMU) provides a limited interface to the controller’s fault management system. As a troubleshooting tool, you can use FMU to:

■Display the last-failure and memory-system-failure entries that the fault management software stores in the controller’s nonvolatile memory.

■Translate many of the event messages that are contained in the entries related to the significant events and failures. For example, entries may contain codes that indicate the cause of the event, the software component that reported the event, the repair action, and so on.

■Set the display characteristics of spontaneous events and failures that the fault management system sends to the PC or terminal, or to the host.

Virtual Terminal Display

Use the virtual terminal display (VTDPY) utility to aid in troubleshooting the following issues:

■Communication between the controller and its hosts.

■Communication between the controller and the devices in the subsystem.

■The state and I/O activity of the logical units, devices, and device ports in the subsystem.
