When Using Thin Provisioning Volumes (TPVs)
The following sections show the series of settings that need to be performed to use Thin Provisioning Pool

Not only can new Thin Provisioning Pool be created, adding or changing volumes that are registered in existing
Thin Provisioning Pools can also be performed.
TPVs can not only be used as virtual logical volumes but also as copy destinations for SnapOPC or SnapOPC+.
