You can change the default setting for the Split Type and Copy Pace system options for all new pairs that you create.

  1. Open the Select Secondary Volumes window of the Create SI Pairs wizard.


  2. In the Select Secondary Volumes window of the Create SI Pairs wizard, click Change Options.


  3. In the Change Options dialog box, complete the following steps, and then click OK:
    • For Split Type, select a split type.

      Values:

      • Non Split (default): The pair is not split.
      • Quick Split: The pair is split, and then the differential data is copied so that the S-VOL is immediately available for read and write I/O. Any remaining differential data is copied to the S-VOL in the background.
      • Steady Split: Differential data is copied, and then the pair is split.
    • For Copy Pace, select the rate at which you want the storage system to copy data.

      Values:

      • Slower: Improved host server I/O performance but slower processing speed.
      • Medium (default): Average processing speed and host server I/O performance.
      • Faster: Faster processing speed but slower host server I/O performance.
