Determining Number of Logical Libraries
You can partition the library into as many logical libraries as there are drives in the library.

Basic Guidelines

• Each logical library must contain at least one drive.
• A library configuration of exactly one logical library equals the entire physical library.
• The library issues a warning to the user if media is moved across logical libraries.

Library Sharing

The library's default configuration allows a single application to operate the library through
a single control path. Often, it is advantageous to be able to share a single library between
heterogeneous (dissimilar) or homogeneous (similar) applications. Some applications (and
some servers) do not allow for sharing a library between systems. Configurations can be
created that enable the library to process commands from multiple heterogeneous
applications and multiple homogeneous applications.
Configure the library so that it is partitioned into separate logical libraries that
independently communicate with separate applications through separate control paths.
This configuration requires no special capabilities from the server or application.
Library Partitioning and Element Addressing
A 2U or 4U library system containing more than one drive can be configured into separate
logical libraries (create partitions). For the 2U library, one to two partitions are available.
For the 4U library, it is possible to configure one to four partitions. Each library must
contain at least one drive per partition.
