Subsystem Monitoring
3.1 Overview
The S12E 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 firmware, which can be accessed using a PC
hyper-terminal connected through the COM1 serial port.
Device status information can be obtained from the FW-
embedded configuration utility. The firmware functions and
settings are fully described in the
Operation Manual
that
came with your system. Please refer to this manual for further
information.
․
SANWatch:
SANWatch 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
SANWatch 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.
