There are two modes of operation for the Convenience Input⁄Output Station while in
Input mode: Insert, and Import. If one or more Virtual Tape Servers are
Import/Export capable, then the Convenience Input⁄Output Station will be in Import
mode.
Cartridge Tape
The 3494 is designed to automate the storage and movement of the Cartridge
System Tape, the Enhanced Capacity Cartridge System Tape, and the 3590 High
Performance Cartridge Tape.
Note: The 3590 High Performance Cartridge Tape can only be used on 3590 High
Performance Magnetic Tape Subsystems. The Cartridge System Tape and
the Enhanced Capacity Cartridge System Tape can only be used on 3490E
Magnetic Tape Subsystems.
The 3494 supports an intermix of the Cartridge System Tape, the Enhanced
Capacity Cartridge System Tape, and the High Performance Cartridge Tape
depending on the model of tape drive subsystem installed. The Enhanced Capacity
Cartridge System Tape is visually distinguished from the Cartridge System Tape by
its two-color (gray and white) plastic case. The High Performance Cartridge Tape is
visually distinguished from the Enhanced Capacity Cartridge System Tape and the
Cartridge System Tape by its black plastic case, blue plastic inserts, and blue
leader block.

. Note the
blue plastic inserts of the High Performance Cartridge Tape cartridge and the
placement of the media-type label (either 1, E, or J).
The vision system identifies the type of cartridge during an inventory or insert
operation by reading a separate, media-type label to distinguish between the three
types of cartridges. A standard Cartridge System Tape is identified by a media-type
label with the character 1. The Enhanced Capacity Cartridge System Tape is
identified with the character E. The High Performance Cartridge Tape cartridge is
identified with the character J. See “Unlabeled Tape Facility” on page 22 for more
information.
Notes:
1. If both 3490 and 3590 drive types are installed in the 3494, all cartridges should
have a label in the seventh character position. See Figure 15 on page 19.
2. The media type of the cartridge can be determined in several ways:
v
The most desirable method is for the vision system to read the seventh
character on the label.
v
If users have cartridges without the seventh character, they may assign
volser ranges (see “Volser Range for Media Types” on page 161) for
determining the media type. If the vision system does not successfully read a
seventh character, the library manager checks the volser read against the
established volser ranges. If the volser is found, the media type that is
associated with the range is used.
v
Additionally, a default media type can be set during a teach operation. The
default media type is used for the cartridge if the vision system cannot
