RAID Subsystem DVA-12T | Installation Manual Subsystem Monitoring | en 21Bosch Security Systems F.01U.027.798 | V1 | 2006.064 Subsystem Monitoring4.1 Subsystem Monitoring OverviewThe RAID subsystem is equipped with a variety of self-monitoring features that help to keepsubsystem 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 theoverall 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 configurationutility.• RAIDWatch: RAIDWatch is a fully integrated, Java-based,Graphical User Interface (GUI) that came with the subsystem and can be used to monitorand maintain the subsystem using your web browsers. Connection to RAIDWatch is madeusing the existing Ethernet ports.• The RAIDWatch Panel View can be customized to show a direct, graphical representationof the RAID subsystem in the content panel of the RAIDWatch screen. Panel View allowsyou to quickly determine the operational status of critical components.• Bosch RAIDWatch Server: The Bosch RAIDWatch Server is a powerful module that runs asan independent program from RAIDWatch and can be installed redundantly on differenthosts. It is used for event notification via email, fax, LAN broadcast, SNMP traps, MSNMessenger, ICQ, SMS (Short Message Service), and the configuration utility screen. TheConfiguration Client helps prevent blind time and keeps you constantly informed as tothe status of the storage management subsystem. Instructions on how to activate theConfiguration Client functionality are given in the RAIDWatch User’s Manual.• LEDs: Device-status-indicating LEDs are located on all active components. These LEDsinform 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 subsystemcontroller 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 controllerboard and must be heeded at all times. Events such as a breaching of the temperaturethreshold will trigger the alarm. If a subsystem manager is present, the manager shoulduse the PC hyper-terminal to determine the cause of the alarm and take the appropriatecorrective measures. (See Section 4.3 Audible Alarm)• Inter-Integrated Circuit (I2C): The I2C bus monitors theoperational 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 otherdisruptive 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 systemevent (like overheating) can cause severe and permanent damage to the subsystem.
