HSM CONTROL PROGRAM AND METHOD
First Claim
1. An HSM control program allowing a computer to execute an HSM control method for managing a file system using primary and secondary storage units, the program allowing the computer to execute:
- a metadata management step that manages, as metadata of a file, primary storage location information which is location information of file data of the file on the primary storage unit, secondary storage location information which is location information of the file data on the secondary storage unit, and a file status value indicating the status of the file, as well as performs control operation on a file;
an HSM information management step that manages HSM information including a replication of the secondary storage location information and policy information based on the file control performed by the metadata management step; and
a data migration step that migrates the file data between the primary and secondary storage units based on the file control performed by the metadata management step and HSM information managed by the HSM information management step.
