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

Permitted

Not permitted

Compatible FlashCopy® V2 and Compatible FlashCopy® SE

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

Using a TSE-VOL as a target volume.

  • Using a pool-VOL as a source volume or target volume.
  • Using a TSE-VOL as a source volume.
  • Increasing the capacity of a DP-VOL used by Compatible FlashCopy® V2 and Compatible FlashCopy® SE.

Compatible PAV

Defining base devices to DP-VOLs

  • Defining base devices to pool-VOLs.
  • Defining alias devices to pool-VOLs.
  • Defining alias devices to DP-VOLs.
  • Defining alias devices to TSE-VOLs.

ShadowImage for Mainframe
  • Using a DP-VOL as a ShadowImage for Mainframe primary volume (P-VOL) or secondary volume (S-VOL).
  • Reclaiming zero pages (the pair status must be PSUS).
  • Using a pool-VOL as a ShadowImage for Mainframe P-VOL or S-VOL.
  • Using a TSE-VOL as a ShadowImage for Mainframe P-VOL or S-VOL.
  • Expanding the capacity of a DP-VOL used in ShadowImage for Mainframe.

TrueCopy for Mainframe

  • Using a DP-VOL as a TrueCopy for Mainframe primary volume (P-VOL) or secondary volume (S-VOL).

  • Using a pool-VOL as a TrueCopy for Mainframe P-VOL or S-VOL.
  • Using a TSE-VOL as a TrueCopy for Mainframe P-VOL or S-VOL.
  • Expanding the capacity of a DP-VOL used in TrueCopy for Mainframe.

Universal Replicator for Mainframe

  • Using a DP-VOL as a Universal Replicator for Mainframe primary volume (P-VOL), secondary volume (S-VOL), or journal volume. The journal volume must be a DP-VOL.

  • Using a DP-VOL as a journal volume that has a mainframe emulation type.
  • Using a DP pool-VOL as a Universal Replicator for Mainframe P-VOL, S-VOL, or journal volume.
  • Using a TSE-VOL as a P-VOL, S-VOL, or journal volume of Universal Replicator for Mainframe.
  • Expanding the capacity of a DP-VOL used as a P-VOL or a S-VOL in Universal Replicator for Mainframe.

Universal Volume Manager

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.

Virtual LVI

Registering Virtual LVI volumes in Dynamic Provisioning for Mainframe pools.

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

Virtual Partition Manager

Performing operations on DP-VOLs and pool-VOLs.

Not available

Volume Migration

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.

  • Using on an external volume with data direct mapping enabled.

  • Using an external volume with data direct mapping enabled as a target volume.
