4	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 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 (I2C): The I2C bus monitors the operational integrity of the cool- ing modules, sensors for RAID controller board/backplane temperature and voltage read- ings.

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.
