Disabling capacity saving settings

The following chart outlines the task flow for disabling capacity saving settings.

• You can disable the setting using the Edit LDEVs window.
• When the capacity saving setting is disabled, data to which compression/deduplication was applied is decompressed, and the used capacity of the pool increases. Before disabling the capacity saving function, verify that the pool has enough free capacity.
• When the capacity saving setting is being disabled, [Rehydrating] is displayed as Capacity Saving Status.
• Even if the capacity saving setting is being disabled, I/O can continue. You cannot cancel disabling it or enable it again.
• The processing time of disabling the capacity saving setting takes long because of data decompression. You can check the progress from Device Manager - Storage Navigator or Command Control Interface. The disabling processing time increases depending on the used capacity of virtual volume. The disabling processing time changes according to the storage system configuration, data layout, and data content.
