stations in only one zone of a dual accessor library, the library selects the accessor in that
preferred zone and maintains FIFO order.
For detailed information about import and export performance in libraries with virtual I/O
slots enabled, refer to Import and export performance with virtual I/O slots.
• Enabling or disabling virtual I/O slots
This section describes how to enable or disable virtual I/O slots in the TS3500 Tape
Library so that the host operates as if it has access to more I/O slots than are actually
available. It also describes how to disable virtual I/O slots.

Cartridge assignment policy
This section describes the cartridge assignment policy for assigning cartridges to specific
logical libraries.
You identify a cartridge by affixing a label to it that bears a volume serial (VOLSER)
number. The cartridge assignment policy allows you to specify one or more ranges of
VOLSERs for logical libraries. For example, you can create a cartridge assignment policy of
36 cartridge VOLSERs that range from 000764 to 000800 for a specific logical library. Note
that VOLSERs in ranges do not include the media-type indicator, such as L2, L3, JA, and so
forth.
When you insert a cartridge into the library and its VOLSER is within a range, the cartridge
assignment policy assigns the cartridge to its logical library. The cartridge must be of the
same media type as that logical library. For example, if you create for Logical Library 1 (a
library of Ultrium drives) a cartridge assignment policy of VOLSERs that range from ABC000
to ABC999 then you insert a cartridge with VOLSER ABC123, the library recognizes that
VOLSER as belonging to the range and assigns it to Logical Library 1, provided that the
cartridge is an Ultrium tape cartridge (and not a different media type, such as a 3592 tape
cartridge).
When an unassigned cartridge is present in the I/O station, the library reads its VOLSER
label and automatically assigns it to the logical library that is specified in the range of
VOLSERs which was previously selected by the system administrator when creating a
cartridge assignment policy. Similarly, when the Advanced Library Management System
(ALMS) is enabled, if you open and close the library's front door the library automatically
performs an inventory. If the library detects a newly inserted, unassigned cartridge, it
assigns the cartridge to the logical library of the VOLSER range that was previously selected
by the system administrator when creating a cartridge assignment policy.
