* The BC/SS pair status must be “PSUS” from the time you split the pairs in a consistency group until the time the status
of all SS pairs in the consistency group change to “PSUS”. If the BC/SS pair status changes while splitting pairs in a
consistency group, the SS data cannot maintain consistency.
