Notes:

  1. (VSP One B20 series) The pair status depends on the settings of the system option modes (SOMs) 448 and 449.

    (VSP One B85) The pair status depends on the settings of advanced system settings No.15 and No.16.

  2. The status after powering on the target secondary site.
  3. The status when a target UR pair has been created.

When recovering from this failure, use the existing source UR environment for the system recovery. The following describes the procedure for recovering to the status before a failure occurs.



  1. Remove the failure on the storage system at the target UR secondary site.
  2. Resynchronize the target UR pair.
  3. Confirm that the UR pair status has changed to PAIR.
