Subsystem Monitoring 
This chapter provides information on how to monitor the subsystem.
Subsystem Monitoring Overview
The subsystem is equipped with a variety of self-monitoring features that help to keep subsys-
tem managers informed of the subsystem operational status. These monitoring features pro-
vide 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:
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)
Inter-Integrated Circuit (I
C): The I
C bus monitors the operational integrity of the cool-
ing modules, sensors for RAID controller board/backplane temperature and voltage read-
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.
