HP XP P9500 Storage - Manual (Page 140)

On open systems, OPEN-V is the only supported emulation type on a THP V-VOL. You can define
multiple THP V-VOLs and assign them to a Thin Provisioning pool.
Relationship between a pool and THP V-VOLs
Before you can use Thin Provisioning, a THP V-VOL and a pool are required. Thin Provisioning
uses the pool volumes in a pool through the THP V-VOLs.
The following figure shows the relationship between a pool and THP V-VOLs.
Creating V-VOLs
You can create a THP V-VOL from any of the following tabs:
•
The LDEVs tab, which appears when Logical Devices is selected.
•
The Pools tab, which appears when Pools is selected.
•
The Virtual Volumes tab, which appears when a pool in Pools is selected.
1. You can create LDEVs from the following tab windows:
•
The LDEVs tab, which appears when Logical Devices is selected.
•
The Pools tab, which appears when Pools is selected.
•
The Virtual Volumes tab, which appears when a pool in Pools is selected.
2. Click Create LDEVs.
The Create LDEVs window appears.
3. From the Provisioning Type list, confirm Thin Provisioning is selected.
If not, select Thin Provisioning from the list.
4. In the System Type option, select a system type.
To create open system volumes, select Open.
5. From the Emulation Type list, confirm OPEN-V is selected.
6. From the Smart Pool field, select Enable when you create the V-VOL for Smart Tiers, and select
Disable when you do not create one.
If no pool is set to Enable in Smart Tiers, Disable is fixed.
