HP XP P9000 Command View Advanced Edition Suite Software 7.6.0-00 User Guide

If a Tiered Storage Manager license has been registered, user can use the Mobility tab to evaluate
and analyze the operation status that is related to a THP/Smart pool. When you delete an unnecessary
THP/Smart pool, THP/Smart volumes created from that pool are also deleted. For this reason, a
prerequisite to deleting a THP/Smart pool is that no THP/Smart volumes from that pool are allocated
to a host.

Creating a THP/Smart pool
You can create a THP/Smart pool using physical volumes. Creating a THP/Smart pool provides more
efficient use of physical storage for virtual volumes allocated to hosts from the THP/Smart pool.
Prerequisites
Tasks to complete beforehand:
• Register the target storage system.
• When defining an external LDEV tier rank, externally connect a storage system that has multiple
performance levels.
• Verify the following when using XP24000/20000 and HP XP P9500 Storage for THP pools:
• Only parity groups from which volumes have already been created can be targets
• Verify the following when using HP XP P9500 Storage for Smart pools:
• Hardware tier: drive type and drive speed (RPM)
• Only parity groups for each hardware tier from which volumes have already been created
can be targets
1. On the Resources tab you can create pools from several locations:
• From General Tasks, select Create Pool.
• Select the storage system, list existing THP Pools, and click Create Pool.
• Select the storage system, list existing THP Pools, and click Actions, then select Create Pool.
2. In the create pool dialog box, configure THP or Smart pools and their characteristics.
