Notes:

  1. For pair creation, the initial copy operations are performed in the order the YKMAKE command is run. For pair resynchronization, the initial copy operations are performed in the order the YKRESYNC command is run. When the YKRESYNC command is run for a consistency group, the initial copy operation begins with the pair having the lowest LDEV number within the group.
  2. When you add remote connection using Business Continuity Manager, if either of the following conditions is met, No is set. If neither of the following conditions are met, Yes is set:
    • Remote connection is added (YKBLDPTH) to a storage system at the other site using remote DKC control function.
    • Remote connection is added (YKBLDPTH) without using the remote DKC control function, and one of the following conditions is met:
      • System option mode 163 is enabled.
      • The primary system CU specified by Add Remote Connection (YKBLDPTH) is used as TPF.
      • The CU emulation type of the port connected to the Business Continuity Manager host is other than I-2107.
