Chapter 1 — Library Overview
LCM and RCM Functionality
The functionality provided by the control module is determined by where
the module is installed and the information on the memory card installed
in the module.

frame, the module functions as the Robotics Control Module (RCM).
Function
Runs the BlueScale software, which provides the BlueScale user interface that is
used to perform all configuration, import/export, and management functions
for the library. The BlueScale user interface is accessed locally through the
library's touch screen. In addition, an embedded web server provides remote
access to the BlueScale web interface and to the XML command interface using
a standard web browser.
In addition to providing the user interface, the BlueScale software running on
the LCM generates and maintains the MLM database, BlueScale encryption
keys, system logs, and other information related to the current system status. It
also handles email operations such as sending a backup file and AutoSupport
logs to preconfigured recipients.
Processes media changer commands from the hosts and storage management
software to control the operation of the robotics. The RCM also stores all of the
information relating to the location and status of each element in the library, as
well as the raw media inventory in its non‐volatile memory. This functionality
allows the library to continue performing backup/restore operations, even
when the user interface provided through the LCM is unavailable.
