Abstract
The storage system eliminates inconsistency between a stub, and a file data storage location indicated by the stub. In a storage system that executes HSM using stubs, information relating to a higher tier, which is a data migration source, is recorded during data migration. The stub in the higher tier is correctly restored using the higher-tier information thus recorded. The stub is restored, and inconsistency between information in the HSM layers is resolved.
