Important: For libraries with serial numbers before 7800K0K, the slots of the lowest row of the
bottom module are inaccessible and can contain a 4-slot I/O station only, so do not load cartridges
into these slots.
3. Insert the magazine into the unit.
4. Push the magazine handle slowly until the magazine release latch snaps into place. The magazine
locks into place.
Important: Push the magazine fully into place until the latch snaps into place.
5. Repeat steps 1 - 3 for each of the other magazines.
See "Accessing cartridges" on page 73.

Verifying the installation

Verify that the library has the current firmware revision, and save the configuration settings. This action
can be helpful if the library requires service.
Verify that the library has the current firmware revision. The library firmware revision is displayed at
Library > Actions > Properties.
1. Verify library firmware and update if needed: Library > Actions > Update Library Firmware
2. Run Library Verify.
3. Save the configuration settings to a file on your computer from the Management GUI: Settings >
Library > Advanced > Save Configuration File.
Having a backup of the library configuration is helpful when the library is recovering from a
configuration error or needs service.

Advanced library configuration

To create and manage multiple logical libraries, utilize the advanced logical library function.

Overview

Overview of advanced features such as multipath architecture, multiple logical libraries, and multiple
control paths.
Multipath architecture
The multipath architecture feature of this tape library allows Open Systems applications to share the
robotics of the library. See "Library sharing" on page 17.
The library features storage area network (SAN) ready multipath architecture. This architecture allows
homogeneous or heterogeneous Open Systems applications to share the library's robotics without
middleware or a dedicated server (host) acting as a library manager. The SAN-ready multipath
architecture makes sharing possible by partitioning the library's storage slots and tape drives into logical
libraries. Servers can then run separate applications for each logical library. This partitioning capability
extends the potential centralization of storage that the SAN enables. Partitioning also provides
investment protection if your application does not support the mixing of drive generations and media in
the same logical library.
The multipath architecture of this library is designed to provide the capability to share the library robotics.
The sharing is accomplished first by partitioning the library into multiple logical libraries (up to the
number of drives installed). Then, each logical library is assigned its own separate and distinct drives,
storage slots, and control paths. Input/output (I/O) slots are shared on a first-come-first-serve basis. This
type of partitioning is designed to allow heterogeneous applications to share the library robotics
independent of each other. Cartridges under library control are not shared between logical libraries, nor
are they allowed to be moved between logical libraries. An example of heterogeneous sharing is a
