Abstract
Methods that can position shuttle cars in a tape storage shuttle complex are provided. One method includes tracking, by a processor, tape drive occupancy in a plurality of library strings of a shuttle complex, the tape drive occupancy indicating that each tape drive in the plurality of library strings is one of occupied and vacant and positioning a set of shuttle cars in the shuttle complex based on the tape drive occupancy in the plurality of library strings. Apparatus and computer program products that can include, perform, and/or implement the methods are also provided.
Claims20
An apparatus, comprising:
- a tape drive occupancy module that tracks tape drive occupancy in a plurality of library strings of a shuttle complex, the tape drive occupancy indicating whether each tape drive in the plurality of library strings is one of occupied and vacant;
- and
- a shuttle car position module that positions a set of shuttle cars in the shuttle complex based on the tape drive occupancy in the plurality of library strings,
- wherein at least a portion of said modules comprise one or more of a set of hardware circuits, a set of programmable hardware devices, and executable code stored on a set of non-transitory computer-readable storage mediums.
A method, comprising:
- tracking, by a processor, tape drive occupancy in a plurality of library strings of a shuttle complex, the tape drive occupancy indicating whether each tape drive in the plurality of library strings is one of occupied and vacant;
- and
- positioning a set of shuttle cars in the shuttle complex based on the tape drive occupancy in the plurality of library strings.
A computer program product comprising a computer-readable storage medium including program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
- track tape drive occupancy in a plurality of library strings of a shuttle complex, the tape drive occupancy indicating whether each tape drive in the plurality of library strings is one of occupied and vacant;
- and
- position a set of shuttle cars in the shuttle complex based on the tape drive occupancy in the plurality of library strings.
