Subsystem Monitoring
This chapter provides information on how to monitor the subsystem.
4.1
Subsystem Monitoring Overview
The subsystem is equipped with a variety of self-monitoring features that help to keep sub-
system managers informed of the subsystem operational status. 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 safe opera-
tion of the subsystem and help ensure the longevity of the subsystems.
Self-monitoring features include:

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.
Bosch Security Systems
Firmware (FW): The RAID controllers in the subsystems come with pre-installed FW. The
FW can be accessed using either the LCD keypad panel or a PC running terminal software
through the RS-232C (audio jack) serial port. Device status information can be obtained
from the FW.
Bosch RAIDWatch: Bosch 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 web browsers. Connection to a Bosch RAIDWatch station is made
using the existing Ethernet ports.
The Bosch RAIDWatch Panel View can be customized to show a direct, graphical repre-
sentation of the subsystem in the content panel of the Bosch RAIDWatch screen. Panel
View allows you to quickly determine the operational status of critical components.
Configuration Client: The powerful Configuration Client sub-module can be used to keep
you informed of system events via a variety of communication methods like email, LAN
broadcast, fax, pager, MSN messenger, ICQ, and SMS. The sub-module runs as an inde-
pendent program from Bosch RAIDWatch main program. The Configuration Client helps
prevent blind time and keeps you constantly informed as to the status of the storage
management subsystem.
LEDs: Device-status-indicating LEDs are placed on all of the subsystems' active compo-
nents. These LEDs inform you of the integrity of a given component or a given link. You
should become familiar with the different LEDs on the subsystem and be aware of their
functions. (See Figure 4.2)
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 jeopar-
dize 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 and if an onsite subsystem manager is present, the manager should, using either
the LCD panel or the PC hyper-terminal, determine the cause of the alarm and take the
appropriate corrective measures. (See Figure 4.3)
