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