Table 9 Priority set for P-VOLs for which initial copy operation is performed
Value set for Priority P-VOL
2 LUN 00
3 LUN 01
1 LUN 02
4 LUN 03
The order of starting initial copy and the Priority which is set for the P-VOLs are shown in the
following table.
Table 10 Relationship between order of starting initial copy and priority set for P-VOLs
Value set for Priority P-VOL Order of starting initial copy
1 LUN 02 1
2 LUN 00 2
3 LUN 01 3
4 LUN 03 4
In this case, as the setting value of the Maximum Initial Copy Activities is 2, initial copy operations
for LUN 02 and LUN 00 are started. If either one of the initial copy operations for LUN 02 and
LUN 00 is completed, the initial copy for LUN 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 Continuous Access Synchronous pairs are
newly added. The P-VOLs of the Continuous Access Synchronous pairs to be newly added and the
Priority are shown in the following table.
Table 11 Priority set for P-VOLs of Continuous Access Synchronous pairs to be added
Value set for Priority P-VOL
2 LUN 10
1 LUN 11
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.
