Note:
  1. The pair status depends on the settings of the system option modes (SOMs) 448 and 449.
  2. The status after powering on the source primary site.

When recovering from this failure, you must perform this failure recovery operations in the target UR environment, and then remove the source UR environment because the system environmental migration for the remote copy function is complete.



  1. Remove the failure on the storage system at the target UR secondary site.
  2. Resynchronize the target UR pair.
The subsequent section provides how to remove the source UR environment in accordance with the procedure in Removing the source environment.
