TrueCopy

You can use Dynamic Provisioning, Dynamic Tiering, or active flash in combination with TrueCopy to replicate V-VOLs.

The following figure illustrates the interaction when the TrueCopy primary volume and secondary volume are also V-VOLs.

TrueCopy P-VOL	TrueCopy S-VOL	Explanation
DP-VOLs	DP-VOLs	Supported.
DP-VOLs	Normal (ordinary) volumes¹	Supported.
Normal (ordinary) volumes¹	DP-VOLs	Supported. Note, however, that this combination consumes the same amount of pool capacity as the original normal volume (primary volume).
Note: Normal volumes include the internal volumes and external volumes that are mapped to the volumes of the external storage system using Universal Volume Manager. For more information about external volumes, see the Universal Volume Manager User Guide.

You cannot specify a Dynamic Provisioning, Dynamic Tiering, or active flash pool-VOL as a primary volume or secondary volume.
