1.4.3 Firmware (FW) and RAIDWatch GUI
Firmware:
The firmware (FW) is pre-installed software used to configure
the subsystem. The FW can be accessed either through the LCD keypad
panel or a terminal emulation program running on a management computer
that is connected to the subsystem’s serial port.
RAIDWatch:
RAIDWatch is a premier, browser-based or Java-based
graphical user interface (GUI) that can be installed on a remote computer
and accessed via the web. The manager communicates with the array via the
connection of the existing host interface or Ethernet link to the array’s
Ethernet port.
1.4.4 Audible
Alarms
The RAID subsystems come with audible alarms that are triggered when
certain active components fail or when certain controller or subsystem
thresholds are exceeded. Whenever you hear an audible alarm from an
RAID subsystem, it is imperative that you determine the cause and rectify
the problem immediately.
Event notification messages indicate the completion or status of array
configuration tasks and are always accompanied by two (2) or three (3)
successive and prolonged beeps.
CAUTION!
Failing to respond when an audible alarm is heard can lead to permanent
damage of the RAID subsystem. When an audible alarm is heard, rectify
the problem as soon as possible.
