Abstract
A data management method is adapted to a hierarchical virtual storage system which virtually uses a library apparatus having a plurality of recording media as a portion of a hard disk apparatus. The data management method manages loading of the recording media to the library apparatus and unloading of the recording media from the library apparatus in a database in units of a set that is formed by a plurality of recording media, and forms a logical volume, which is a recording unit of a data file with respect to the library apparatus, by one or a plurality of recording media, and manages the logical volume in the database in correspondence with the set.
Claims31
A data management method for a hierarchical virtual storage system which virtually uses a library apparatus having a plurality of recording media as a portion of a hard disk apparatus, comprising:
- managing loading of the recording media to the library apparatus and unloading of the recording media from the library apparatus in a database in units of a set that is formed by a plurality of recording media;
- and
- forming a logical volume, which is a recording unit of a data file with respect to the library apparatus, by one or a plurality of recording media, and managing the logical volume in the database in correspondence with the set.
A data management apparatus for a hierarchical virtual storage system which virtually uses a library apparatus having a plurality of recording media as a portion of a hard disk apparatus, comprising:
- a database;
- and
- a control part configured to manage loading of the recording media to the library apparatus and unloading of the recording media from the library apparatus in the database in units of a set that is formed by a plurality of recording media, and to form a logical volume, which is a recording unit of a data file with respect to the library apparatus, by one or a plurality of recording media, and manage the logical volume in the database in correspondence with the set.
A hierarchical storage apparatus comprising:
- a hard disk apparatus;
- a library apparatus, loadable with a plurality of recording media, and virtually used as a portion of the hard disk;
- and
- a hierarchical control server including a database and a control part,
- said control part managing loading of the recording media to the library apparatus and unloading of the recording media from the library apparatus in the database in units of a set that is formed by a plurality of recording media, and forming a logical volume, which is a recording unit of a data file with respect to the library apparatus, by one or a plurality of recording media, and managing the logical volume in the database in correspondence with the set.
A computer-readable storage medium which stores a program for causing a computer to manage data in a hierarchical virtual storage system which virtually uses a library apparatus having a plurality of recording media as a portion of a hard disk apparatus, said program comprising:
- a procedure causing the computer to manage loading of the recording media to the library apparatus and unloading of the recording media from the library apparatus in a database in units of a set that is formed by a plurality of recording media;
- and
- a procedure causing the computer to form a logical volume, which is a recording unit of a data file with respect to the library apparatus, by one or a plurality of recording media, and to manage the logical volume in the database in correspondence with the set.
