Pair splitting methods

You can use one of the following methods to split pairs:

• Steady Split: Copies the differential data to the S-VOL then splits the pair. The split S-VOL is identical to the P-VOL at the time of the split.

 You cannot Steady Split pairs that are assigned to a CTG.

• Quick Split: The pair is split prior to data copy 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.

CCI is required.

• Consistency group pair-split: Simultaneously split all of the pairs in a CTG. You can use this method with CCI.
