* The SI pair status must be “PSUS” during the period between when create the HTI pair to store snapshot data and when HTI 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 SI pair status changes to a status other than “PSUS” while HTI is storing snapshot data for the consistency group, the snapshot data consistency cannot be guaranteed.
