* The BC/SS pair status must be “PSUS” during the period between when FS starts to store snapshot data for a
consistency group and when the status of all pairs in the consistency group changes to “PSUS”. If the BC/SS pair
status changes to a status other than “PSUS” when you are storing snapshot data for the consistency group, the snapshot
data consistency is not guaranteed.
