2. From the Work Items navigation pane, select Library —> ALMS. The Advanced
Library Management System Mode screen displays.
3. Follow the instructions on the screens to enable ALMS.
What to do next
ALMS enables the transition from static partitioning to dynamic partitioning in the TS3500
Tape Library. When ALMS is enabled for the first time in a library that is partitioned, the
following events occur:
• The contents of each partition are automatically migrated to ALMS logical libraries.
No action is required with any logical library labels that are present. These labels will be
ignored after ALMS is enabled.
• Each logical library is given a default name that can then be changed as required.
• During the enablement process, the library is unavailable for about 5 minutes, in
addition to the time it takes to re-inventory each frame. (Refer to Inventory times for
more information.)
Note: After ALMS is enabled, it is possible to increase the Maximum cartridges and
Maximum VIO cartridges values for the logical library.

Using virtual I/O slots
This section describes the benefits of using virtual input/output (I/O) slots.
When the Advanced Library Management System (ALMS) is enabled, you can enable virtual
I/O slots in the TS3500 Tape Library so that the library automatically queues all cartridge
moves between the I/O station and the storage slots. This makes the process of adding and
removing cartridges easier and faster.
The TS3500 Tape Library has I/O stations with I/O slots that allow you to import and export
up to 224 cartridges at any given time. The I/O slots are also known as import/export
elements (IEEs). Virtual I/O slots increase the quantity of available I/O slots by allowing
storage slots to appear to the host as I/O slots. These storage slots are also called virtual
import/export elements (VIEEs). With virtual I/O slots, the library automatically moves
cartridges from the I/O stations to the storage slots. In this way, the library enhances its
import and export capabilities.
The goal of virtual I/O slots is to reduce the dependencies between the system
administrator and library operator so that each performs their import and export tasks
without needing the other to perform any actions:
