Utilities and Exercisers
Controller software includes utilities and exercisers to assist in troubleshooting and
maintaining the controller and the other modules that support its operation. These utilities
and exercisers include:
■ Fault management utility (FMU)
■ Video terminal display (VTDPY) utility
■ Disk inline exerciser (DILX)
■ Format and device code load utility (HSUTIL)
■ Configuration (CONFIG) utiltity
■ Code load and code patch (CLCP) utility
■ CLONE utility
■ Field replacement utility (FRUTIL)
■ Change volume serial number (CHVSN) utility
■ Device statistics (DSTAT) utility—not supported
FMU
The 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 non-volatile 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, the repair action, and so on.
