Use cases
A copy group can be deleted even if it is configured of simplex volumes or paired volumes.
The following shows use cases that can be deleted a copy group.
◦ Deleting a copy group configured of simplex volumes.
◦ Deleting a copy group configured of paired volumes.
Pair operation by specifying a copy group
Specifying a copy group and creating a pair. Pairs are created for which the same device names
of LDEV defined in respective device groups of the LDEVs. Therefore, it is required to give a same
device name for the item to be operated as a pair.
If a consistency group attribute is valid and no consistency group ID is specified, automatically
assign a consistency group ID (1 copy group=1 consistency group). If the automatic consistency
group assignment is specified and the other pairs in a copy group already have consistency group
IDs, assign the same consistency group ID.
