A FlashCopy® establish with Preserve Mirror request was issued to devices in a multi-target PPRC configuration. This requires that the pair set characteristics command (PSETCHAR) be issued, indicating one and only one leg on the source and target is to be used for Preserve Mirror.
Command processing ends.
Issue a set characteristics for one and only one leg of the source and the target pairs in the multi-target PPRC configuration and reissue the FlashCopy establish command.
