Changing the maximum initial copy activities option

You can change the maximum number of volumes that can be copied concurrently by adjusting the Maximum Initial Copy Activities setting (range = 1 to 128, default = 64). For example, you can increase this setting when you need to create or resynchronize a large number of pairs concurrently, and you can decrease this setting when you need to limit the impact of initial copy operations on system performance.

For details and instructions, see Setting the maximum initial copy activities option.

• Performance of the primary storage system depends on this setting and the amount of I/O activity. You can limit the impact of initial copy operations on system performance by using the default setting.

• When you change the maximum initial copy activities setting, the new setting applies to pairs created or resynchronized after the change, not existing pairs.
