The 9714 Library Storage Module (LSM) is the hardware component in an 
automated cartridge system. An automated cartridge system is a removable media, 
robotic system that mounts cartridges into a storage cell or into a drive for read and 
write operations. 

 and 

 show the major components 

of an LSM, described in the following pages. 

■

The LSM has four major, internal components:

•

A robot

•

Storage cells for 40 to 100 cartridges

•

A cartridge access port (CAP) that can hold one cartridge

•

One to six drives

The robot moves cartridges between storage cells and drives when the customer 
server software makes a request. The robot includes the Z column assembly and the 
hand. 

 shows the robot components.

The Z column assembly contains a Z column and Z carriage. The Z column 
attaches to the floor and the ceiling of the LSM, and rotates 140 degrees to allow 
access to all the cells in the LSM. 

The hand mounts to the Z carriage. The Z carriage moves the hand vertically up 
and down the Z column to storage cells, drives, or the CAP. 

A camera located on the hand reads the cartridge volume serial numbers 
(VOLSERs) during audits, but is not used to locate cartridges during robotic moves 
or read the VOLSERs of cartridges in the drives. If you manually replace a cartridge 
in a drive, the host memory will retain the old VOLSER. 

The camera reads the VOLSERs of all the cartridges in the LSM cells and stores 
the information on the PRC (processor) card. You must request a host update to 
add the information to the host memory. 

An audit occurs when you power-on the LSM, open and close the LSM door, 
perform an initial program load (IPL) of the LSM, or make a request at the 
customer server console to audit the LSM.
