An RV of a maximum of four volumes can be set for one PV.
For DynamicDataReplication, an RV of a maximum of three volumes can be set at a time, however.
An RV can be allocated to a maximum of two disk arrays for one PV.
The DynamicDataReplication can be set in only one layer in the disk array.
You cannot set dRV directly for dRV.
Volumes with different volume capacities cannot be set as a pair.
Unless the OS type is the same, the pair setting cannot be executed.
