General Information
This chapter describes the hardware components of the A4846A Library Storage
Module (LSM). For LSM management software information and drive
information, refer to the publications that pertain to these specific topics.
The 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/write operations. Figure 1–2
and Figure 1–1 show the major components of an LSM, described in the following
pages.
Library Storage Module Components
The LSM has four major, internal components:
S
A robot
S
Storage cells for 40 to 100 cartridges, in increments of 20 slots.
S
A cartridge access port (CAP) that can hold one cartridge
S
One to six drives
Robot
The robot moves cartridges between storage cells and drives when the LSM
management software makes a request to move cartridges. The robot consists
mainly of the Z column assembly and the hand. Figure 1–2 shows the robot
components.
The Z column assembly contains a Z column and Z carriage. The Z column
attaches to the floor and ceiling of the LSM. The Z column 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, and 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. The camera does not read the VOLSERs of cartridges in the drives. If you
manually replace a cartridge in a drive, the host memory will retain the previous
VOLSER. You must request a host update using the LSM management software to
add the information to the host memory.
