Abstract

A management system receives a job definition condition that defines a migration job corresponding to partial migration that is part of data migration for replacement from a replace source storage system to a replace target storage system. The management system selects one or more source volumes and creates a migration job for the one or more source volumes in accordance with the job definition condition. The migration job is a job in which, for each of the one or more source volumes, a target volume is created in the replace target storage system, and in which data is migrated from each of the one or more source volumes to a corresponding one of the one or more target volumes. The management system executes each of a plurality of migration jobs.

First claim

The invention claimed is:

1. A management system for replacement from a replace source storage system to a replace target storage system, the replacement including data migration that is migration of data in a volume set held by the replace source storage system to the replace target storage system, the management system comprising:
an interface device coupled to a plurality of storage systems;
a storage resource configured to store management information including information with respect to a configuration of the plurality of storage systems; and
a processor coupled to the interface device and the storage resource,
the processor being configured to
(A) receive a designation of the replace target storage system among the plurality of storage systems and a designation of the replace source storage system among the plurality of storage systems,
(B) receive a job definition condition that defines a migration job corresponding to partial migration that is part of data migration for replacement from the replace source storage system to the replace target storage system,
(C) select one or more volumes from the volume set as one or more source volumes and create a migration job for the selected one or more source volumes, based on the management information in accordance with the job definition condition, the migration job being a job in which, for each of the selected one or more source volumes, a target volume that is a volume having the same capacity as that of the source volume is created in the replace target storage system, and in which data is migrated from each of the one or more source volumes to a corresponding one of the one or more target volumes,
(D) respectively execute a plurality of migration jobs respectively corresponding to a plurality of partial migrations included in the data migration,

(E) display, using the capacity of a plurality of source volumes for the replace source storage system, progress in terms of the capacity of target volumes for which data has been migrated to the replace target storage system.

2. The management system according to claim 1 , wherein the progress display in (E) is a display in which, for each of the replace source storage system and the replace target storage system, the volume capacity for data migrated by a completed migration job is distinguished from the volume capacity for data being migrated by a migration job in execution.

3. The management system according to claim 2 , wherein a plurality of replace source storage systems is present for the replace target storage system, and
the progress display in (E) is a target progress display and a plurality of source progress displays deployed in the same screen, the target progress display is a display of the progress for the replace target storage system, the plurality of source progress displays corresponds to the respective replace source storage systems, and each of the source progress displays is a display of progress for the replace source storage system corresponding to the source progress display, and
a display mode of a source progress display of a replace source storage system corresponding to a migration job in a suspension state is a display mode meaning the suspension state.

4. The management system according to claim 3 , wherein the progress display in (E) is a snapshot display that is the plurality of source progress displays and the target progress display deployed in one screen, and the processor is configured to
(F) display, for the replace target storage system, time-series changes in the progress of data migration from the plurality of replace source storage systems, and
the processor is configured to receive a designation of a time for the display in (F) and perform the snapshot display in (E) at the designated time.

5. The management system according to claim 1 , wherein the volume set includes a plurality of volumes accessed by one or more hosts, the job definition condition is a host, and
in (C), when the job definition condition represents a host, the selected one or more source volumes are all volumes accessed by the host identified in accordance with the job definition condition.

6. The management system according to claim 1 , wherein, when the volume set includes a primary volume paired with a secondary volume, the processor is configured to create, during migration job execution in (D), a pair having, as a primary volume, a target volume corresponding to a source volume serving as the primary volume.

7. A management method for replacement from a replace source storage system to a replace target storage system, the replacement including data migration that is migration of data in a volume set held by the replace source storage system to the replace target storage system, the management method comprising:
(A) receiving a designation of the replace target storage system among the plurality of storage systems;
(B) receiving a designation of the replace source storage system among the plurality of storage systems,
(C) receiving a job definition condition that defines a migration job corresponding to partial migration that is part of data migration for replacement from the replace source storage system to the replace target storage system,
(D) selecting one or more volumes from the volume set as one or more source volumes and creating a migration job for the selected one or more source volumes, in accordance with the job definition condition, the migration job being a job in which, for each of the one or more source volumes, a target volume that is a volume having the same capacity as that of the source volume is created in the replace target storage system, and in which data is migrated from each of the one or more source volumes to a corresponding one of the one or more target volumes,
(E) executing each of a plurality of migration jobs corresponding to a plurality of partial migrations included in the data migration,
(F) displaying, using the capacity of a plurality of source volumes for the replace source storage system, progress in terms of the capacity of target volumes for which data has been migrated to the replace target storage system.
