Procedure 7 To specify number of volumes to copy concurrently
1. In the Remote Web Console main window, select Actions > Remote Copy > Continuous Access
Journal Z > Optional Operation.
2. Click to change the mode from View to Modify.
3. Right-click the value in Activities in the right pane, then select Change System Option from the
menu. The System Option dialog box displays.
4. In the Maximum Initial Copy Activities box, enter the number of volumes that you want to be
copied concurrently during initial copy and resynchronization operations. Valid values range
from 1 to 128 volumes. The default is 64 volumes.
•
This setting can impact performance on the primary system, depending on the number
specified and the amount of I/O activity. By using the default, 64 volumes, you limit the
impact of initial copy operations on system performance.
•
When you create or resychronize a greater number of pairs than you define in Maximum
Initial Copy Activities, the system processes the specified maximum number, and starts
additional pairs after one of the specified number is synchronized.
For example, if you specify 70 for Maximum Initial Copy Activities and then create 75
pairs, the system starts the first 70 pairs but does not start the 71st pair until one of the
pairs is synchronized.
