4 Subsystem Monitoring

4.1 Subsystem Monitoring Overview

The RAID subsystem is equipped with a variety of self-monitoring features that help to keep

subsystem managers informed of the subsystem operational status. These monitoring fea-

tures provide vital feedback to help you maintain the operational integrity of the subsystem.

Prompt response to warnings and subsystem component failure notifications will improve the

overall operation of the subsystem and help ensure the longevity of the RAID subsystem.

Self-monitoring features include:

• Firmware (FW): The controller in the RAID subsystem comes with preinstalled firmware,

which can be accessed using a PC hyper-terminal connected through the RAID sub-

system’s COM port. Device status information can be obtained from the FW configuration

utility.

• RAIDWatch: RAIDWatch 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 using your web browsers. Connection to RAIDWatch is made

using the existing Ethernet ports.

• The RAIDWatch Panel View can be customized to show a direct, graphical representation

of the RAID subsystem in the content panel of the RAIDWatch screen. Panel View allows

you to quickly determine the operational status of critical components.

• Bosch RAIDWatch Server: The Bosch RAIDWatch Server is a powerful module that runs as

an independent program from RAIDWatch and can be installed redundantly on different

hosts. It is used for event notification via email, fax, LAN broadcast, SNMP traps, MSN

Messenger, ICQ, SMS (Short Message Service), and the configuration utility screen. The

Configuration Client helps prevent blind time and keeps you constantly informed as to

the status of the storage management subsystem. Instructions on how to activate the

Configuration Client functionality are given in the RAIDWatch User’s Manual.

• LEDs: Device-status-indicating LEDs are located on all active components. These LEDs

inform you of the integrity of a given component or a given link. You should become famil-

iar with the different LEDs that are present on the subsystem and be aware of their func-

tions. (See Section 4.2 Status-indicating LEDs)

• 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.

These events usually jeopardize the functional and operational integrity of the controller

board and must be heeded at all times. Events such as a breaching of the temperature

threshold will trigger the alarm. If a subsystem manager is present, the manager should

use the PC hyper-terminal to determine the cause of the alarm and take the appropriate

corrective measures. (See Section 4.3 Audible Alarm)

• Inter-Integrated Circuit (I2C): The I2C bus monitors the

operational integrity of the cooling modules, RAID controller board temperature and volt-

age readings.

Subsystem monitoring is a necessary part of subsystem management. If failure events or other

disruptive events are detected and reported, the subsystem managers must take the appropri-

ate action to rectify the problem. Failure to act in a properly specified manner to a system

event (like overheating) can cause severe and permanent damage to the subsystem.
