Supported functions:

  • Using a V-VOL as a TrueCopy primary volume (P-VOL) or secondary volume (S-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 in TrueCopy.
  • Using a deduplication system data volume as a TrueCopy P-VOL or S-VOL.

Not supported functions:

  • Using a pool-VOL as a TrueCopy P-VOL or S-VOL.
  • Using a deduplication system data volume as a TrueCopy P-VOL or S-VOL.

In addition, you can use Dynamic Provisioning in combination with TrueCopy to replicate V-VOLs. You cannot specify a Dynamic Provisioning pool-VOL as a primary volume or secondary volume.

This figure shows the interaction when the TrueCopy primary volume and secondary volume are also DRD-VOLs.



TrueCopy P-VOL TrueCopy S-VOL Explanation
DRD-VOLs DRD-VOLs Supported
DRD-VOLs External volumes* Supported
External volumes* DRD-VOLs 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.
