You can decrease or shrink the size of a data volume across the Replicated Data Set (RDS) using the online volume shrink feature. This feature is helpful in reclaiming unused space to better use your resource.

The new volume size can be specified in Sectors, kilobytes (KB), megabytes (MB), gigabytes (GB) or terabytes (TB), and the specified value must be less than the maximum size of the volume.

The feature calculates the amount of space that can be freed from the volume to create a new smaller volume size. The size of a volume after the shrink volume operation is approximately the difference of the current volume size and the number of maximum reclaimable bytes. The new volume size is displayed in the Veritas Enterprise Administrator (VEA) GUI.
