Supported functions:
- Using a V-VOL as a Universal Replicator primary volume (P-VOL), secondary volume (S-VOL), or a DP-VOL as a 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 DRS-VOL 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.

Explanation |
|---|---|---|---|
| Capacity saving-enabled V-VOLs (DRS-VOLs) | Capacity saving-enabled V-VOLs (DRS-VOLs) | Capacity saving-enabled V-VOLs (DRS-VOLs) | Supported |
| Capacity saving-enabled V-VOLs (DRS-VOLs) | External volumes * | Capacity saving-enabled V-VOLs (DRS-VOLs) | Supported |
| External volumes | Capacity saving-enabled V-VOLs (DRS-VOLs) | Capacity saving-enabled V-VOLs (DRS-VOLs) | Supported. Note that this combination consumes the same amount of pool capacity as the external volume (primary volume). |
