Controller Display
Each array controller in the Smart Array Cluster Storage system contains an
integrated LCD display. This module displays informational and error messages,
shows the current status of the module, and provides an interface for user input. The
system combines traditional POST messages issued by PCI-based array controllers
with runtime event notification messages for this new set of controller display
messages. The display module consists of the following components:
• A two-line, 20-column display text window
• Four buttons
• Two LEDs
Types of Messages
The display module is capable of storing up to 100 messages. When the message log
is full, the system deletes the oldest message to make room for the most recent one.
The types of messages include:
• Error Messages—Error messages indicate a problem that may require user
action.
The Fault LED illuminates when you view an error message. It also illuminates
to indicate that an unviewed error message is in the queue and was followed by
other types of messages. When scrolling backwards to view all error messages,
the LED illuminates only when an error message is in the text display window.
• Informational Messages—Informational messages provide feedback on
non-critical changes.
• User Input Messages—User input messages indicate an issue that requires a
choice. The user can choose a selection before the end of a time-out period or
allow the controller to default to a standard choice. User input messages only
occur during system power up.
The Fault LED flashes when a user input message is in the text display window
and requires input. If the user does not provide input within the time-out period,
the message remains, but the LED stops flashing.
