Abstract

A method for use in viewing compression and migration status is disclosed. A logical volume is selected for compression into a compressed logical volume. A destination storage pool for the compressed logical volume is selected. The logical volume is compressed during migration of the logical volume to the destination pool. Unified status information of progress of the compression and migration is presented. A system for use in viewing compression and migration status is also disclosed.

Claims (28)

1. A method for use in viewing compression and migration status, the method comprising:

selecting a logical volume for compression into a compressed logical volume;

selecting a destination storage pool for the compressed logical volume;

compressing the logical volume in-line during migration of the logical volume to the destination pool; and

presenting unified status information of progress of the in-line compression and migration during migration of the logical volume.

2. The method of claim 1 wherein a reservation is made in the destination storage pool for the compressed logical volume.

3. The method of claim 1 wherein the logical volume selected for compression is a traditional Logical Unit Number (LUN).

4. The method of claim 1 wherein the compressed logical volume is a Thin LUN Unit (TLU).

5. The method of claim 1 wherein the logical volume selected for compression is selected by a user.

6. The method of claim 1 wherein the logical volume selected for compression is selected by a computer.

7. The method of claim 1 wherein the destination storage pool is selected by a user.

8. The method of claim 1 wherein the destination storage pool is selected by a computer.

9. The method of claim 1 wherein compression and migration cannot be managed independently.

10. The method of claim 1 wherein a rate of migration is synchronized with the rate of compression.

11. The method of claim 1 wherein an association is established between migration states and compression states.

12. The method of claim 1 wherein the unified status information is obtained by polling.

13. The method of claim 1 wherein the unified status information comprises a unified completion percentage.

14. The method of claim 1 wherein the method is performed using a command line interface (CLI).

15. The method of claim 1 wherein the method is performed using a graphical user interface (GUI).

16. A system for use in viewing compression and migration status, the system comprising:

first logic selecting a logical volume for compression into a compressed logical volume;

second logic selecting a destination storage pool for the compressed logical volume;

third logic compressing the logical volume in-line during migration of the logical volume to the destination pool; and

fourth logic presenting unified status information of progress of the in-line compression and migration during migration of the logical volume.

17. The system of claim 16 wherein a reservation is made in the destination storage pool for the compressed logical volume.

18. The system of claim 16 wherein compression and migration cannot be managed independently.

19. The system of claim 16 wherein an association is established between migration states and compression states.

20. The system of claim 16 wherein the unified status information comprises a unified completion percentage.
