• Use cases

As an example of pair operation, the following shows use cases that can be created a pair

by specifying a copy group.

◦ Creating a pair in cases where the device names and the numbers of LDEVs in two device

groups in a copy group configured of simplex volumes are the same.

In the following example, pairs are created with LDEVs that have the same device name,

A to A and B to B.

◦ Creating a pair in cases where the device names and the numbers of LDEVs in two device

groups in a copy group configured of simplex volumes and paired volumes are the same.

In the following example, a pair is created with LDEVs for the device name A. And no

operation is performed for the volumes of device name B that are already formed into

copy pairs.

◦ Creating a pair in cases where different device names exist in two device groups in a

copy group configured of simplex volumes.

In the following example, a pair for device name A can be created, but not for device

name B and C because they have different names.

◦ Creating a pair in cases where the device names in two device groups in a copy group

configured of simplex volumes and paired volumes are different.

In the following example, a pair for device name A to A can be created. For the device

name B and C, although it does not change the paired status, but an error occurs because

they have different device names.
