For DynamicDataReplication, an RV of a maximum of three volumes can be set at a time, however.

• 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.
