Deleting copy groups

You can delete an existing copy group using the Pair Configuration Wizard.

TIP:

Before you delete mainframe copy groups (with EXCTG specification) using the Pair Configuration
Wizard, you should first delete all pairs using the Change Pair Status Wizard. When copy groups
are deleted by CTG or pair units, the consistency of the EXCTG configuration is not guaranteed and
task execution might fail.

To delete a copy group:

1.

In the Hosts view, Storage Systems view, or Pair Configurations view, display information about
the copy group for which you want to edit a copy pair configuration definition.

For details on the Hosts view, Storage Systems view, and Pair Configurations view, see the
following:

, page 294

2.

In the displayed subwindow, select a copy group or select one or more volumes that belong to
the copy group to be deleted. Alternatively, make sure that copy group information is displayed,
and then click Pair Management.

The Pair Configuration Wizard starts with the 1. Introduction page displayed.
