Compaq HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide
Using VTDPY to Check for Communication
Problems
Use the virtual terminal display (VTDPY) utility to get information about the
following communications:
■ Communication between the controller and its hosts
■ Communication between the controller and the devices in the subsystem
SET CLI_EVENT_REPORTING
SET NOCLI_EVENT_REPORTING
enable and disable the asynchronous errors reported at the CLI prompt
(for example, “swap signals disabled” or “shelf has a bad power supply”).
Preceded by “%CER.” By default, these errors are reported (SET
CLI_EVENT_REPORTING). These errors are cleared with the CLEAR
ERRORS_CLI command.
SET FAULT_LED_LOGGING
SET NOFAULT_LED_LOGGING
enable and disable the solid fault LED event log display on the local
terminal. Preceded by “%FLL.” By default, logging is enabled (SET
FAULT_LED_LOGGING).
When enabled, and a solid fault pattern is displayed in the OCP LEDs, the
fault pattern and its meaning are displayed on the maintenance terminal.
For many of the patterns, additional information is also displayed to aid in
problem diagnosis.
In cases of automatic hardware reset (for example, power failure or
pressing the controller’s reset button), the fault LED log display is
inhibited because automatic resets do not allow sufficient time to
complete the log display.
SHOW PARAMETERS displays the current settings associated with the SET command.
SET command PERMANENT preserves the SET command across controller resets.
