• 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.
