In this case, as the setting value of the Maximum Initial Copy Activities is 2, initial copy operations
for LDEV 02 and LDEV 00 are started. If either one of the initial copy operations for LDEV 02 and
LDEV 00 is completed, the initial copy for LDEV 01 is started.
The next example explains the assignment of the scheduling order of initial copy operations in
cases where initial copy is already performed and two volume pairs are newly added. The P-VOLs
of the data volume pairs to be newly added and the Priority are shown in the following table.

If initial copy is already started and if any initial copy is newly added, the additional initial copy
is started after the previously performed initial copy is completed. The Priority of all the initial copy
operations being performed is shown in the following table.

Priority is determined within the range of the number of initial copy operations performed at the
same time. Therefore, until the first initial copy operations complying with the order of the Priority
are completed, the additional initial copy operations are not started.
