You can modify the capacity saving setting (deduplication and compression) for volumes.
When the capacity saving setting of a volume is set to Deduplication and compression, you cannot change the capacity saving setting of that volume to Compression.
If you change the capacity saving settings while it is enabled, rehydrating data might take some time.
If the storage system is VSP One B26 or VSP One B28, you can use compression acceleration. We recommend using compression acceleration because it allows you to reduce the load that data compression places on the storage system. Note that changing the capacity savings compression method when using compression acceleration means that the new method is applied to all volume data and the processing takes some time.
For details on the capacity saving function, see the Provisioning Guide.
- Identify the server name.
- Identify the volume name.
- Check whether the capacity saving setting is specified.
- Check whether compression acceleration is set.
- If the planned changes can impact the free space on the pool, check the current amount of free space.
- Make sure that the user performing the procedure has been assigned the Storage Administrator (Provisioning) role.
