that supports operations on a group basis during specification. An

the copy direction for TCA and CAJ copy groups after
resynchronization.

Even if the command has terminated successfully, make sure that the transition of the copy pair
status was performed, using the
YKQUERY

to resynchronize a copy pair is executed. An appropriate Resync Options panel is displayed to
specify parameters for the
YKRESYNC
command depending on the copy type.
The Resync Options panel is shown in Figure 125 (page 165) to Figure 128 (page 166) .
