You can split ShadowImage pairs. When a pair is split, data can be read from or written to the secondary volume. You can split pairs in units of copy group or split individual pairs.

CAUTION:
Volume Migration pairs created by using other management tools might be displayed in the list. If you are using Volume Migration, check the copy type in the pair list on the copy group details window and proceed with caution.
  • Obtain the following:
    • Copy group name or pair names
    • Whether to run in quick mode
    • Copy speed
  • You must have the Storage Administrator (Local Copy) role.
  1. From the navigation tree, select Local Protection > ShadowImage Copy Groups.
  2. To split pairs in units of copy group, select the copy group and then click Split ShadowImage Copy Groups in the action bar of the copy group details page. To split a pair, select the copy group containing the pair and then select the pair on the copy group details page. On the ShadowImage Pair page, click Split ShadowImage Pairs in the action bar.

    You can select multiple copy groups or pairs to work with at the same time.

  3. Specify the required items, and then click Submit.
