1.
Change the copy pair status of the existing journal group to DUPLEX to make the copy direction
the same within the group.
2.
From the ISPF panel, define a copy group container.
If the type of the copy group to be changed to an EXCTG is already a copy group container,
this procedure is not necessary. If you change separate copy groups to an EXCTG, define
them as a copy group container.

From the ISPF panel, define the copy group container as an EXCTG.

Because an existing journal group has not been registered in the EXCTG yet, the YKZ296E
message indicating that the journal group has not been registered in the EXCTG is output.

Execute the YKMAKE command with SELECT(COND) specified.
The journal group is registered in the EXCTG of the storage system.
