Figure 70 Array option settings in the Optional Operation pane
• Max Initial Copy: Number of volumes that can be copied concurrently during an initial copy
operation.
Figure 71 System Option pane
• Maximum Initial Copy Activities: Number volumes that can be copied concurrently during an
initial copy operation. A value within the range of 1 to 128 can be specified. The default
is 64 volumes.
Maximum Initial Copy Activities can impact the performance of the primary array, depending on
amount of I/O activity and number of pairs being registered at the same time. If Maximum Initial
Copy Activities is 64 volumes, you can limit the impact of initial copy activities on array performance.
For example, if you set the maximum initial copy activities to 64 volumes and add 65 pairs at the
same time, the primary array starts the first 64 pairs and does not start the 65th pair until one of the
pairs is synchronized. When you change the maximum initial copy activities setting, the new setting
applies to pairs created after the setting was changed, not to existing pairs.
• Set: Closes the System Option pane, and adds settings to the Preset list.
• Cancel: Cancels settings.
