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.

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.

  • A Thin Image pool-VOL cannot be shared with Dynamic Provisioning, Dynamic Tiering, or active flash.

Virtual Partition Manager CLPR setting

If DP-VOLs and pool-VOLs related to the same pool are assigned to a CLPR, the DP-VOLs and pool-VOLs in the same pool should be assigned to the same CLPR.

For details about CLPRs, see the Performance Guide.
