When Deduplication/Compression of Thin Provisioning Pool is enabled, Container volume and Block Map volume are automatically created. In addition, the capacity reduction rate is displayed. It is automatically updated every hour.
When deleting a Thin provisioning Pool for which Deduplication/Compression is enabled, disable Deduplication/Compression first and delete it.
Refer to the following ETERNUS Disk storage system manuals for information on the Deduplication/Compression function of Thin Provisioning Pool.

Note
If the firmware version number of the following device is less than V10L20, a total capacity of Thin Provisioning Pool exceeding 2 TB cannot properly be displayed. When using a Thin Provisioning Pool exceeding 2 TB, the firmware version number must be V10L20 or later:
ETERNUS DX80 S2/DX90 S2
If the status of Deduplication/Compression is "Error", a hyphen ("-") is displayed in Capacity Reduction Rate. When an automatic update is triggered after recovery from "Error", the indicator for Capacity Reduction Rate is changed from a hyphen ("-") to a numerical value. If you want to check the latest capacity reduction rate before it is automatically updated, perform the Reload Conf. operation for the target ETERNUS Disk storage system.
