Interoperability of DP-VOLs and pool-VOLs

DP-VOLs and pool-VOLs can be used in conjunction with other software products with certain limitations and restrictions. The following table lists the software products and indicates the operations that are permitted and not permitted for each product.

Software product (user guide)

Permitted

Not permitted

Thin Image (Thin Image User Guide)

Using a DP-VOL as a Thin Image primary volume.

  • Using a DP-VOL as a Thin Image secondary volume or pool-VOL.
  • Using a Dynamic Provisioning or Dynamic Tiering pool-VOL as a Thin Image primary volume, secondary volume, or pool-VOL.

  • Using an LDEV with accelerated compression enabled as a primary volume or secondary volume of a Thin Image pair.
  • Using a deduplication system data volume as a primary volume or secondary volume of a Thin Image pair.

Data Retention Utility (Provisioning Guide)

Performing operations on DP-VOLs.

  • Performing operations on DP pool-VOLs.
  • Performing operations on an external volume with data direct mapping enabled.
  • Performing operations on LDEVs with accelerated compression enabled.
  • Performing operations on a deduplication system data volume.

global-active device (Global-Active Device User Guide)

Using a DP-VOL as a global-active device primary volume (P-VOL) or secondary volume (S-VOL).

  • Using a DP-VOL as a quorum disk.
  • Using a pool-VOL as a global-active device P-VOL or S-VOL.
  • Increasing the capacity of a DP-VOL used by global-active device.
  • Using an external volume with data direct mapping enabled as a quorum disk.
  • Using a DP-VOL with data direct mapping enabled as a quorum disk.
  • Using a deduplication system data volume as a global-active device P-VOL or S-VOL.

LUN Manager (Provisioning Guide)

LUN Security (Provisioning Guide)

Performing operations on DP-VOLs.

  • Performing operations on DP pool-VOLs.
  • Performing operations on an external volume with data direct mapping enabled.
  • Performing operations on LDEVs with accelerated compression enabled.
  • Performing operations on a deduplication system data volume.

ShadowImage (ShadowImage User Guide)

Using a DP-VOL as a ShadowImage primary volume (P-VOL) or secondary volume (S-VOL).

If a pool contains both the P-VOL and S-VOL of a pair and deduplication is enabled for the pool, only one copy of the P-VOL data is saved physically due to deduplication of the P-VOL and S-VOL data. If you want to protect the P-VOL data, use separate pools for the P-VOL and S-VOL.

  • Using a pool-VOL as a ShadowImage P-VOL or S-VOL.
  • Increasing the capacity of a DP-VOL used by ShadowImage.
  • Reclaiming zero pages of a DP-VOL is determined by the pair status. For details, see ShadowImage pair status for reclaiming zero pages.
  • Using a deduplication system data volume as a ShadowImage P-VOL or S-VOL.

TrueCopy (TrueCopy User Guide)

Using a DP-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.

  • Using a pool-VOL as a TrueCopy P-VOL or S-VOL.
  • Increasing the capacity of DP-VOL used as a P-VOL or S-VOL of a TrueCopy pair.
  • Using a deduplication system data volume as a TrueCopy P-VOL or S-VOL.

Universal Replicator (Universal Replicator User Guide)

Using a DP-VOL as a Universal Replicator primary volume (P-VOL), secondary volume (S-VOL), or journal volume. However, the journal volume must be a DP-VOL that has OPEN-V emulation type.

For disaster recovery (DR) operations, apply the same capacity saving setting to the P-VOL and S-VOL of the pair by assuming failover.

  • Using a DP pool-VOL as a Universal Replicator P-VOL, S-VOL, or journal volume.
  • Increasing the capacity of a DP-VOL used as a P-VOL or S-VOL of a Universal Replicator pair.
  • 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 DP-VOL with capacity saving enabled (DRD volume) as a journal volume.
  • Using a deduplication system data volume (DSD volume) as a Universal Replicator P-VOL or S-VOL.

Universal Volume Manager (Universal Volume Manager User Guide)

Using Universal Volume Manager volumes as pool-VOLs.

  • Increasing the capacity of a DP-VOL that is mapped to the Universal Volume Manager. If you try to increase the capacity of a DP-VOL with the conventional LDEV operation, the capacity of the DP-VOL will not be changed. In this case, remove the mapping between the DP-VOL and Universal Volume Manager, increase the capacity of the external volume used as a pool-VOL, and then perform the mapping between the DP-VOL and Universal Volume Manager again.
  • Setting the data direct mapping attribute on a DP-VOL with capacity saving enabled (DRD volume).
  • Setting the data direct mapping attribute on a deduplication system data volume (DSD volume).
  • Enabling capacity saving on a DP-VOL from a pool with Universal Volume Manager pool-VOLs.

Virtual LUN (Provisioning Guide)

Registering Virtual LUN volumes in Dynamic Provisioning pools.

  • Performing Virtual LUN operations on volumes that are already registered in a DP pool.

Virtual Partition Manager (Performance Guide)

Performing operations on DP-VOLs and pool-VOLs.

Not applicable

(For details, contact customer support.)

Using a DP-VOL as a migration source or a migration target.

The maximum capacity of a DP-VOL used as a migration source or target is the same as the maximum capacity of a DP-VOL.

  • Using on pool-VOLs.
  • Increasing the capacity of DP-VOL used by Volume Migration.
  • Reclaiming zero pages of V-VOL used by Volume Migration.
  • Using on a deduplication system data volume.

Volume Shredder (Volume Shredder User Guide)

Use on DP-VOLs.

  • Using on pool-VOLs.

  • Increasing the capacity of DP-VOL used by Volume Shredder.
  • Reclaiming zero pages of V-VOL used by Volume Shredder.
  • Performing operations on a DP-VOL with capacity saving enabled (DRD volume).
  • Performing operations on a deduplication system data volume.
