If you refer to the used capacity during I/O or copy processing by Volume Migration or the replication program products, for example ShadowImage and Universal Replicator, even if the Full allocation is enabled on the virtual volume, the displayed used capacity may be different from the actual capacity because there is a gap between the times of information gathering about the mapped capacity and the reserved page capacity.
