System Monitoring
This chapter provides information on how to monitor the A12U and A08U RAID
subsystems.
3.1 Subsystem Monitoring Overview
Both the EonStor A08U-G2421 and A12U-G2421 subsystems are equipped with a
variety of self-monitoring features that help to keep subsystem 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 operation 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. The FW
capabilities have been fully described in the “Generic Operation Manual”
that came with your subsystems. Please refer to this manual for further
information.
• 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 web browsers. Connection to a
RAIDWatch station is made using the existing Ethernet ports.
The RAIDWatch Panel View can be customized to show a direct, graphical
representation of the subsystem in the content panel of the RAIDWatch
screen. Panel View allows you to quickly determine the operational status
of critical components. Detailed information for the RAIDWatch manager
is given in the RAIDWatch User’s Manual included in the Product Utility
CD that came with your subsystem.
• 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 independent
program from RAIDWatch main program. 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
