The pop-up menu is displayed.

4. Select the Change Reserve command in the pop-up menu.
The Set Reserve Attribute dialog box opens.
Note: Select only un-reserved and unpaired volumes in order to use the
Change Reserve command.
5. On the Set Reserve Attribute dialog box, assure that the right volume(s)
are displayed, and then click OK.
The setting will be reflected in the Preview List on the Pair Operation
window.
