When you resynchronize the TrueCopy for Mainframe pair in the Open/MF consistency group which consists of one pair of the primary storage system and the secondary storage system by Business Continuity Manager, all pairs in the consistency group are resynchronized. If the host is accessing the S-VOL of the TrueCopy pair, the TrueCopy pair is also resynchronized simultaneously. Resynchronize the pair after you reconfirm the status of all TrueCopy pairs and all TrueCopy for Mainframe pairs in the consistency group.
When you remove the TrueCopy for Mainframe pair in the Open/MF consistency group which consists of one pair of the primary storage system and the secondary storage system by Business Continuity Manager, only the TrueCopy for Mainframe pairs in the consistency group are removed. If you want to remove the TrueCopy pair simultaneously, you must remove the pairs by CCI.
