Tape Management Software

Enter an audit request at the host console
The camera on the hand reads the labels on the cartridges, microcode assigns the cell
locations, and the LLC processor card records the assignments. When the Media Check
feature is on, the robot attempts to pick up any unreadable, unlabeled, or improperly
placed cartridges. If unretrievable, library status will be "not ready."

Tape Management Software
The tape management software provides the instructions to perform tape read and write
operations and robotic move operations. When the library is in automated mode, these
operations occur without manual intervention. The software determines where the
cartridge is located by accessing audit data uploaded from the library. The software then
allocates the drive to receive the cartridge.

Electronics Module
The electronics module (EM) consists primarily of the LLC card, which is inside the EM,
on the left side as you face the EM from the rear of the library. The interface connections
and personality module are on the EM frame. One or two Fibre Channel router cards can
also be installed in the EM depending on the library model.
LLC Card
The LLC card, in the EM, is the processor card. It contains all the hardware necessary to
maintain the robot, servo, and vision control. It also contains an operator panel interface,
a SCSI interface (HVD or LVD, selectable), an Ethernet interface, eight (L80), four (L40),
or two (L20) serial drive ports, and a Customer Services Engineering (CSE) port.
The card stores the library capacity information from the personality module and the
volume serial numbers of the cartridges in the library cells.
Personality Module
The personality module is a connector that stores the library cell capacity information
(10, 20, 40, 60, or 80 cells). The library will not operate unless an authorized module is
attached to the rear of the EM.
