3.1. Subsystem Monitoring Overview
The Galaxy GHDX2-2430S-24F4D and GHDX2-2430R-24F4D subsystems are equipped
with a variety of self-monitoring features that keep you informed of the subsystem’s
operational statuses. These monitoring features provide vital feedback to help you
maintain the operational integrity of the subsystem. Prompt response to warnings and
component failure notifications will help ensure data integrity and the longevity of the
RAID subsystem.
Self-monitoring features include:
Management firmware (FW): The firmware manages the array, provides device
status information, and is preinstalled in the subsystem controller. You can access
firmware functionalities using either the LCD keypad panel or a PC running a
terminal emulation program and is connected through the subsystem’s COM 1 RS-
232C (audio jack) serial port. The firmware is fully described in the firmware
Operation Manual that came with the subsystem. Please refer to this manual for
further details.
RAIDWatch: RAIDWatch is a Java-based program that came with the subsystem
and can be used to monitor and manage the subsystem locally or remotely over
TCP/IP. You can use the powerful Configuration Client or Notification Process
Center (NPC) sub-modules to keep you informed over a variety of communications
methods such as fax, pager, email, etc. For further details on the installation and
operation of RAIDWatch, please refer to the RAIDWatch User’s Manual.
LEDs: Device-status-indicating LEDs are placed on all of the active components to
inform users of the integrity of a given component. You should become familiar with
the different LEDs and be aware of their functions.
