Specifications for VLL/LUSE Devices

WARNING! LDEVs larger than 2 TB cannot be remotely copied to an HP XP1024/XP128 Disk

Array or an HP XP512/XP48 Disk Array. If you need more information, contact HP technical

support (see “Calling HP Technical Support” (page 86) for instructions).

Virtual LVI/LUN volumes from the same VDEV can be configured with different emulation types as

long as the emulation type is from the same emulation family (for example, all open-system volumes

or all 3390s). Open and mainframe volumes are not allowed in the same parity group.

Virtual LVI/LUN Size Calculation

When creating a CV, you can specify the capacity of each CV. However, there is a margin of

error between the user-specified CV capacity and the actual CV capacity. To estimate the actual

capacity of a CV, use a mathematical formula.

The capacity of a CV or an LDEV consists of two types of capacity:

• The user area capacity that can store the user data

• The capacities of all areas that are necessary for an LDEV implementation, including the control

information

In this manual, the sum of these two types of capacities is called the entire capacity. This section

explains how to calculate the user area capacity and the entire capacity per CV.

Implemented LDEVs consume this entire capacity from the VDEV capacity without exception.

Therefore, even if the sum of user areas of multiple CVs and the user area of one CV are the same
