Abstract

A storage management apparatus is provided, including: a receiving unit that receives a copy command instructing a storage apparatus to copy data in a source volume among a plurality of volumes created to the storage apparatus, to a destination volume; a determination unit that obtains, from the storage apparatus, information on a configuration of the source volume specified in the copy command, determines a property for creating the destination volume based on the obtained information on the configuration of the source volume, and instructs the storage apparatus to create the destination volume; and a copy instructing unit that instructs a copy of the data in the source volume, into the destination volume that is created.

Claims

1. A storage management apparatus, comprising:

a receiving unit that receives a copy command instructing a storage apparatus to copy data in a source volume among a plurality of volumes created to the storage apparatus, to a destination volume;

a determination unit that obtains, from the storage apparatus, information on a configuration of the source volume specified in the copy command, determines a property for creating the destination volume based on the obtained information on the configuration of the source volume, and instructs the storage apparatus to create the destination volume; and

a copy instructing unit that instructs a copy of the data in the source volume, into the destination volume that is created.

2. The storage management apparatus according to claim 1, wherein the information on the configuration of the source volume is a property for creating the source volume and a redundancy of the source volume.

3. The storage management apparatus according to claim 1, wherein the information on the configuration of the source volume is a property for creating the source volume and a physical disk type of the source volume.

4. The storage management apparatus according to claim 1, wherein the determination unit specifies, when a copy type specified in the copy command is a differential copy, a redundancy group for the source volume, as a redundancy group for the destination volume to be created, and

the determination unit species, when the copy type specified in the copy command is a full copy, a redundancy group other than the redundancy group for the source volume, as a redundancy group for the destination volume to be created.

5. A storage apparatus comprising:

at least one storage device that comprises a storage region capable of storing data;

a configuration managing unit that creates a part of the storage region in the at least one storage device, as a plurality of volumes;

a receiving unit that receives, from a host apparatus, a copy command instructing a copy of data in a source volume among the created plurality of volumes, to a destination volume;

a determination unit that obtains, from the configuration managing unit, information on a configuration of the source volume specified in the copy command, determines a property for creating the destination volume based on the obtained information on the configuration of the source volume, and instructs the configuration managing unit to create the destination volume; and

a copy unit that copies the data in the source volume, into the destination volume that is created.

6. Anon-transitory computer readable storage medium having a storage management program stored therein, the storage management program causing a computer to:

receive a copy command instructing a storage apparatus to copy data in a source volume among a plurality of volumes created to the storage apparatus, to a destination volume;

obtain, from the storage apparatus, information on a configuration of the source volume specified in the copy command, determine a property for creating the destination volume based on the obtained information on the configuration of the source volume, and instruct the storage apparatus to create the destination volume; and

instruct a copy of the data in the source volume, into the destination volume that is created.

7. The non-transitory computer readable storage medium according to claim 6, wherein the information on the configuration of the source volume is a property for creating the source volume and a redundancy of the source volume.

8. The non-transitory computer readable storage medium according to claim 6, wherein the information on the configuration of the source volume is a property for creating the source volume and a physical disk type of the source volume.

9. The non-transitory computer readable storage medium according to claim 6, wherein the storage management program further causes the computer to:

specify, when a copy type specified in the copy command is a differential copy, a redundancy group for the source volume, as a redundancy group for the destination volume to be created, and

specify, when the copy type specified in the copy command is a full copy, a redundancy group other than the redundancy group for the source volume, as a redundancy group for the destination volume to be created.
