About pool-VOLs

Pool-VOLs are grouped together to create a pool. When a new pool is created, the available
pool-VOLs are selected in the Select Pool VOLs window and added to the Selected Pool Volumes
table. Every pool must have a pool-VOL with System Area.
The pool-VOLs contained in a pool can be added or deleted. Removing a pool-VOL does not delete
the pool or any related THP V-VOLs. You must delete all THP V-VOLs related to the pool before the
pool can be deleted. When the pool is deleted, all data in the pool is also deleted.

Creating pools

The following procedure tells how to create a pool. This procedure is for setting up Thin Provisioning
Z.
Prerequisites
Before creating a pool, you must install the proper amount of shared memory, and you must have
a V-VOL management area in shared memory. When shared memory is added, the V-VOL
management area is automatically created. To add shared memory, contact your HP representative.
One pool-VOL with system area is defined for a pool. The priority of the pool-VOL with system
area is assigned according to the data drive type. The available capacity of the pool-VOL with
system area is deducted from the management area capacity. The management area capacity
stores the management information of program products that use the pool. If Thin Provisioning Z,
or Smart Tiers Z is used on a mainframe system, 3.8 GB are used as the management area in the
pool-VOL with system area.
When the pool is created, a pool-VOL with system area is assigned the priority shown in the
following table.
Priority
1
2
3
4
5
If multiple pool-VOLs of the same data drive type exist, the priority of each is determined by the
internal index of the storage system.
