Subsystem Monitoring
Overview
The 16 bay and 24 bay iSCSI Galaxy RAID subsystem is equipped
with a variety of self-monitoring features that help keep system
managers informed of the subsystem operational statuses. These
monitoring features provide vital feedback to help you maintain the
operational integrity of the subsystem. Prompt response to warnings
and subsystem component failure notifications will ensure data
integrity and help ensure the longevity of the subsystem.
The monitoring features include:
Firmware
: The RAID controller in the subsystem is
managed by preinstalled FW, which can be accessed using
a PC hyper-terminal connected through the serial port.
Device status information can be obtained from the FW-
embedded configuration utility. The FW is fully described in
the
Operation Manual
that came with your system. Please
refer to this manual for further information.
Galaxy Array Manager:
Galaxy Array Manager is a fully
integrated, Java-based, Graphical User Interface (GUI) that
came with the subsystem and can be used to monitor and
maintain the subsystem locally or remotely over TCP/IP
network. The management session is made using the
10/100BaseT management port. Please refer to the
Galaxy
Array Manager User’s Manual
for further details.
LEDs
: Device-status-indicating LEDs are located on all
modules. These LEDs inform you of the integrity of a given
component or a host/management link. You should become
familiar with the various LEDs and be aware of their
functions.
Audible alarm:
An audible alarm is present on the
subsystem controller board and will be triggered if any of a
number of threatening events occurred.
