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.

Explanation

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.
