optimization is not performed, the used capacity (the physical capacity that is allocated to volumes in the
entire TPP) is not reduced. Refer to [Optimize TPV/FTV Capacity] for details.

This function cannot be used if the allocation method is changed from "Thin" to "Thick" when the free
space in the TPP or FTRP has been insufficient.

This function cannot be used when the capacity releasing from the server is being performed.
