Figure 13-6 Check with Global Copy whether all data was replicated to the new volume
This approach is not really practical though. ICKDSF also allows you to query the status of a
Global Copy primary volume and displays the amount of data which is not yet replicated, as
shown in Example 13-1.
Example 13-1 Check through ICKDSF query commands that all data is replicated

ICK00700I DEVICE INFORMATION FOR 6102 IS CURRENTLY AS FOLLOWS:

After all applications are stopped or shut down Global Copy eventually replicates all data
across and the respective count is zero, as shown in Example 13-2 on page 262.
