Volume Migration

You can use Dynamic Provisioning or Dynamic Tiering in combination with Volume Migration to migrate DP-VOLs.

The following shows the interaction when the Volume Migration source volume and target volume are also DP-VOLs.

Using Dynamic Provisioning or Dynamic Tiering and Volume Migration


Volume Migration source volume	Volume Migration target volume	Explanation
DP-VOLs	DP-VOLs	Supported.
DP-VOLs	Normal (ordinary) volumes*	Supported.
Normal (ordinary) volumes*	DP-VOLs	Supported. Note, however, that this combination consumes the same amount of pool capacity as the normal volume.
*Normal volumes include the internal volumes and external volumes that are mapped to the volumes of the external storage system using by Universal Volume Manager. For more information on external volumes, see the Universal Volume Manager User Guide.

You cannot specify a Dynamic Provisioning or Dynamic Tiering pool-VOL as the Volume Migration source volume and target volume.

If you specify the DP-VOL as the source volume, you must not specify the DP-VOL that uses the same pool of the source volume.

For details about the migration of DP-VOLs used in the following pairs, see Volume Migration User Guide.
