The following table lists the interaction when the Business Copy P-VOL and S-VOL are also THP
V-VOLs.

Snapshot
You can use Thin Provisioning or Thin Provisioning Z in combination with Snapshot to replicate
V-VOLs.
•
The pool for Snapshot cannot be the same pool used for Thin Provisioning or Thin Provisioning
Z.
•
Up to 128 pools in total can be used for Thin Provisioning (including Smart Tiers), Thin
Provisioning Z, and Snapshot.
•
A pool-VOL cannot be shared among Thin Provisioning (including Smart Tiers), Thin Provisioning
Z, and Snapshot.
Cache Partition CLPR setting
THP V-VOLs and the associated pool volumes should be assigned to the same CLPR.
•
For a Thin Provisioning or Smart Tiers pool, different CLPRs can be assigned to THP V-VOLs
in the same pool. In this case, the CLPR assigned to the pool volumes is ignored.
For detailed information about CLPRs, see the HP P9000 Cache Partition User Guide or the Hitachi
Storage Command Suite Hitachi Tiered Storage Manager User Guide (MK-94HC090).
