Library Partitioning and Element Addressing
Library 4U systems with firmware versions of 1.70 and higher, and containing at least 2
drives, have the ability to be configured into logical libraries (create partitions). It is
possible to configure 1, 2, 3, or 4 partitions in the 4U library. Additionally the 2U library
with two drives can be configured into one or two partitions. Each library must contain at
least one drive per logical library (partition).

Partitioning of 2U Libraries

When two half-height drives are installed in a 2U library, the library firmware will support
partitioning. The first partition will contain the first magazine and the first drive. The
second partition will contain the second magazine and the second drive. The Mail Slot (if
configured as I/O) will be shared.

Partitioning of 4U Libraries

When one or more half-height drives are added to a 4U library, the library firmware will
support partitioning. The first drive is Drive 1, the drive above it is called Drive 2, and so
forth.
Configuration of a One-Partition System
A one-partition system configured for a 4U library contains any and all drives present in
any drive positions, and it will contain all four magazines. When configured with one logical
partition, the Element Address assignments will be as follows:
• DTE assignments will be as shown in the figure below.
