Capacity optimization is being reserved (*2) for a TPV or an FTV.
"Capacity Optimization" is a function that releases the allocated physical area when data in the physical area
that is allocated to a TPV or an FTV is filled with zeros.
If "Start Optimizing TPV/FTV Capacity after migration" is enabled for the RAID migration function, the
migration source volume is reserved for capacity optimization.

Mirroring function regardless of whether the volume is protected. If this attribute is displayed, the
volume might be the one that is left in the storage system due to unsuccessful creation.

An ODX Buffer volume. ODX Buffer volumes cannot be protected.
When the volume is being used by the Storage Cluster function, "Enable" is displayed. When no volumes
are used for the Storage Cluster function, "Disable" is displayed.
This item is displayed only when "Enable" is selected for the Storage Cluster function.
When the volume is being used by the Virtual Volume function, "Enable" is displayed. When no volumes
are used by the Virtual Volume function, "Disable" is displayed.
