Working with THP V-VOLs

About THP V-VOLs

Thin Provisioning Z requires the use of THP V-VOLs, which are virtual volumes with no physical
memory space. In Thin Provisioning Z, multiple THP V-VOLs can be created.
A THP V-VOL is a volume in a thin provisioning storage system. It is the virtual volume from a THP
pool. Data in the THP pool is used via a THP V-VOL. A THP V-VOL is a virtual LU to some hosts.
On mainframe systems, 3390-A is the supported emulation type on a THP V-VOL.

Relationship between a pool and THP V-VOLs

Before you can use Thin Provisioning Z, a THP V-VOL and a pool are required. Thin Provisioning
Z uses the pool volumes in a pool through the THP V-VOLs.

Creating Volumes

You can use the procedures in the section to create THP V-VOLs in Command View Advanced
Edition or Remote Web Console.
