STORAGE SYSTEM, CONTROL APPARATUS, AND METHOD FOR CONTROLLING STORAGE SYSTEM

摘要

A storage system includes a library apparatus, a storage apparatus, and a control apparatus including a processor. The processor is configured to execute a copy processing of copying data of a plurality of logical volumes from a storage apparatus to a first recording medium. The copy processing includes a read processing of reading first data of a first logical volume from the storage apparatus, and a first write processing of writing the first data to the first recording medium. The processor is configured to execute a second write processing of writing second data of the first logical volume to the storage apparatus. The processor is configured to interrupt the first write processing and execute the second write processing in a case where a conflict occurs between the second write processing and the first write processing, and resume the copy processing from a leading part of the first logical volume.

1. A storage system comprising:
a library apparatus configured to
store therein a plurality of portable recording media, andread data from or write data to the plurality of portable recording media; a storage apparatus configured to
temporarily store therein data of a logical volume, the stored data being to be recorded on a recording medium among the plurality of portable recording media; and a control apparatus including:
a processor configured to
execute a copy processing of copying data of a plurality of logical volumes from the storage apparatus to a first recording medium among the plurality of portable recording media, the copy processing including
a read processing of reading first data of a first logical volume among the plurality of logical volumes from the storage apparatus, anda first write processing of writing the first data to the first recording medium,execute a second write processing of writing second data of the first logical volume to the storage apparatus,interrupt the first write processing and execute the second write processing in a case where a conflict occurs between the second write processing and the first write processing during execution of the copy processing,invalidate data written to the first recording medium through the interrupted first write processing, andresume the copy processing from a leading part of the first logical volume.
