A Thin Image installation typically includes the Thin Image software, Dynamic Provisioning software, and CCI.

Thin Image

Use the Thin Image software on the Device Manager - Storage Navigator (HDvM - SN) computer that is connected to the service processor (SVP) by means of the TCP/IP local area network (LAN).

If a logical volume assigned as a namespace on the NVM subsystem with the NVMe-oF connection is specified as a P-VOL or an S-VOL of a Thin Image pair, CCI must be used. The pair operations cannot be performed from HDvM - SN.

Dynamic Provisioning

Use the HDP software on the HDvM - SN computer. A user license is required to use HDP.

Since Thin Image uses a portion of the HDP licensed capacity for its pool capacity, reserve enough HDP licensed capacity to run both HDP and Thin Image and to accommodate the Thin Image pairs or pools that you will create.

Thin Image and HDP pool-VOLs are also referred to as used volumes. The licensed capacity must exceed the total capacity of used volumes.

CCI

When you use CCI to define multiple Thin Image pairs in a consistency group, you can only specify one consistency group for a group defined by the configuration definition file for CCI.

Note: The configuration definition file for CCI is a group that is not a consistency group.

If you create a new pair and define the pairs in a consistency group for a group you defined using the configuration definition file for CCI, and the pair is already defined in a consistency group, the pair is defined in the same consistency group even if you try to create a new pair and assign it to a different consistency group.
