Logical Volume States

A volume is in the inventory if an entry (in the inventory) for the volser is in the
database. The following state is associated with a logical volume:

Physical Volser Validity Checking

As a physical cartridge is added to the 3494 Tape Library inventory, the Library
Manager checks the volser to ensure that it is readable, is not already in the
inventory, and is not otherwise invalid.
The convenience I/O station is in either Import mode or Insert mode, depending
upon the capabilities of the VTSs in the 3494 Tape Library and the configuration of
the 3494 Tape Library.
The convenience I/O station is in Import mode when the 3494 Tape Library has at
least one VTS that is capable of Export and Import operations and this mode was
not deselected.
The convenience I/O station is in Insert mode when the 3494 Tape Library does
not have a VTS that is capable of Export and Import operations.
The mode of the convenience I/O station is stored so that the Library Manager
"remembers" the mode across shutdowns. When the mode is determined, the
stored mode is used each time the Library Manager initializes. The mode changes
if the configuration changes or if the VTS capabilities change.
When the convenience I/O station is in Import mode, the 3494 Tape Library adds
any J-, K-, JA-, JB-, and JJ-type cartridges to the database in the Unassigned
category.
Note: Media type JB is not supported with VTS.
A volume is in the inventory, and the Library Manager determines that it
is not in the position that the inventory indicates.
A volume is mounted currently on a drive, or a mount was accepted for
the volume.
The vision system read a defective external bar code label on a volume, or
the volume does not have an external label. If the vision system is not
operational, this state is not modified.
The volume required movement when the 3494 Tape Library was in
Manual mode. The volume is flagged in the inventory as a Manual mode
volume until it is moved successfully or audited in Auto mode or during
an inventory update.
A volume is mounted currently on a drive, or a mount was accepted for
the volume.
