Cartridge Access Port (CAP) Processing Functions
CAP processing functions control cartridge enter and eject functions. The HSC provides
operator commands and utilities which permit you to:
• enter cartridges into the library
• eject cartridges from the library.
The CAP is the focal point for the activities of entering or ejecting cartridges. At least one
CAP is located on the access door of every LSM, and indicators are provided for the
operator to identify what CAP operations are active. At some points, operator interaction
is required. Refer to your ACS hardware operator’s guide for more information about
CAPs.
CAP processing functions described in this section include:
• entering cartridges into the library using the ENter command or ENTEr utility
• ejecting cartridges from the library using either the EJect command or EJECt utility
• CAP exception processing
• releasing an allocated CAP.
Enter and eject operations are accomplished concurrently with other normal LSM
operations: automated mounts, automated dismounts, cartridge exchanges, etc.
For multiple CAPs, each enter and eject operation is processed separately. The user can
run concurrent tasks against CAPs on a single LSM.
PCAPs are used for single cartridge enter and eject operations. These are controlled by the
user through the Tape Management Interface (TMI). Refer to the
Interface to Tape
Management Systems Manual .
Operator commands and detailed instructions for controlling CAP processing functions
are described in the
HSC Operator’s Guide; utilities are discussed in Chapter 4, ‘‘Utility
Functions’’ in this document.
Entering Cartridges into the Library
To enter cartridges into the library, execute the HSC ENter command, SENter command,
or ENTer utility and identify which CAP is to be used for the operation. Specifying the
cap-id is optional for the ENter command. Following the procedures described in Chapter
3, ‘‘Operating an Automated Cartridge System’’ in the HSC Operator’s Guide , open the
CAP door, place cartridges into the CAP cells, and close the CAP door.
The CAP automatically locks when the door is pushed closed. The robot scans the
Tri-Optic label (must be unique) of a cartridge, and the cartridge is moved by the robot to
an empty cell in one of the LSM panels.
For a CAP in automatic mode, do not issue an ENter command. The operator need only
open the door, insert cartridges, and close the door. No other operator intervention is
required.
