Supported functions:
- Using a DP-VOL or V-VOL as a Universal Replicator primary volume (P-VOL), secondary volume (S-VOL), or journal volume. The journal volume must be a DP-VOL.
For disaster recovery (DR) operations, apply the same capacity saving setting to the P-VOL and S-VOL of the pair by assuming failover.
- Expanding the capacity of a V-VOL used as a P-VOL or a S-VOL in UR.
Not supported functions:
- Using a DP pool-VOL as a UR P-VOL, S-VOL, or journal volume.
- Reclaiming zero pages of a DP-VOL used by a journal volume.
- Using an external volume with data direct mapping enabled as a journal volume.
- Using a DP-VOL with data direct mapping enabled as a journal volume.
- Using a DRD-VOL with capacity saving enabled as a journal volume.
- Using a deduplication system data volume (DSD volume) as a P-VOL, S-VOL, or journal volume of a UR pair.
In addition, you can use Dynamic Provisioning in combination with UR to replicate V-VOLs. You cannot specify a Dynamic Provisioning pool-VOL as a primary volume, secondary volume, or journal volume.
This table lists the supported UR and Dynamic Provisioning volume combinations.

DRD-VOLs | DRD-VOLs | DRD-VOL | Supported |
DRD-VOLs | External volumes * | DRD-VOL | Supported |
External volumes | DRD-VOLs | DRD-VOL | Supported. Note that this combination consumes the same amount of pool capacity as the external volume (primary volume). |
* For details about the external volume, see the VSP One Block Universal Volume Manager User Guide. |
