Cartridge
Note: Due to the similarity in structure of their barcodes, a cartridge of type K is
occasionally read by the 3494 Tape Library as type Q . On these occasions,
the Library Manager automatically converts cartridge type Q to type K to
correct this condition.
The 3494 Tape Library uses a volser range table to allow cartridges of different
types with non-IBM-standard labels to be recognized. The volser range table allows
an operator to associate a cartridge type with a range of volsers. If a cartridge isn’t
labeled, the Library Manager examines the volser range table to determine whether
the volser range of the cartridge falls into one of the defined ranges. If so, the
matching cartridge type from the volser range table is assigned to the cartridge.
If the volser range of the cartridge does not match any range in the volser range
table, the default cartridge type (if defined) is assigned to the cartridge. The default
cartridge type is defined during a teach operation during system configuration and
is displayed in the Operational Status window as shown in Figure 88 on page 159.
If the cartridge volser range does not match any of those in the volser range table
and there is no default cartridge type defined, the cartridge is ejected. If a cartridge
has a legible cartridge type label, the label takes precedence over the volser range
table and default cartridge type.
Note:
Refer to “Volser Ranges for Media Types” on page 237 for information on
configuring the volser range table.
Cartridges with labels not conforming to any of the descriptions listed in Table 4
on page 33 can still be used in the tape library. Any unrecognized cartridge type
characters (that is, any that are not listed in Table 4 on page 33) will be ignored by
the 3494 Tape Library, and the volser range table or the default cartridge type will
determine the cartridge’s cartridge type. Note that the volser range table must be
configured as described in “Volser Ranges for Media Types” on page 237 when
using cartridges with non-IBM-standard media labels.
