2.6 Subsystem Monitoring
The RAID subsystem comes with a number of different monitoring methods that provide you
with continual updates on the status of the system and individual components. The following
monitoring features are included in the subsystem.
2.6.1 I
2
C bus
The following elements are interfaced to the RAID controller over a non-user-serviceable I
2
C
bus:
• PSU modules
• Cooling modules
• Temperature sensors (for the temperature of the backplane board and controller board)
2.6.2 LED Indicators
The following active components come with LEDs to indicate the status of the individual com-
ponent:
• RAID controller (5 LEDs)
• LCD panel (3 LEDs)
• BBU (2 LEDs)
• Cooling modules (2 LEDs)
• PSU modules (1 LED)
• Drive trays (2 LEDs)
2.6.3 Firmware (FW) and Bosch RAIDWatch GUI
Firmware: The firmware is pre-installed software used to configure the subsystem. The latest
firmware functionalities include Task Scheduler, Intelligent Drive Handling, and Media Scan.
Media Scan handles low quality drives in both the degraded mode and during the rebuild pro-
cess. Maintenance tasks will then be performed on an entire array or specific hard drives. Var-
ious options are user-configurable such as priority, start time, and execution internals.
Bosch RAIDWatch: Bosch RAIDWatch is a premier web-based graphics user interface (GUI)
that can be installed on a remote computer and accessed via the web. The manager communi-
cates with the array via the connection of the existing host interface or Ethernet link to the
array’s LAN port.
2.6.4 Audible Alarms
The RAID subsystem comes with audible alarms that are triggered when certain active compo-
nents fail or when certain (controller or subsystem) thresholds are exceeded. Whenever you
hear an audible alarm from the 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.
