There are two methods to create a TPP: automatic drive selection and manual drive selection.
■
Automatically selecting drives to create TPPs
To create a new TPP automatically, input Disk Type, RAID Type, and TPP capacity. The
controlling CM of the RAID groups that configure the TPP is determined automatically.
The procedure to create a TPP by selecting drives automatically is as follows:
Procedure

Click [Create] in [Action].
2
Select "Automatic" for the create mode, specify the other parameters, and click

Name
Input a TPP name. An existing TPP name cannot be specified.
The following input conditions apply:

Registering the license for the Thin Provisioning feature is required to

When encryption mode is disabled, TPP encrypted by CM cannot be
created.

Once a TPP has been created, the encryption status cannot be
changed.

TPPs cannot be created in the following conditions:
-

When the maximum capacity of Thin Provisioning Pools are already
registered in the ETERNUS DX Disk storage system
-
When the resources for creating TPPs (such as the number of RAID
groups, the number of volumes, etc.) are insufficient
(When the maximum number of RAID groups or volumes already
exist, TPP cannot be created)
