Before enabling PPRC extended distance, ensure that a PPRC path is active between the primary logical subsystem or storage control and the recovery logical subsystem or storage control. The establish path process, defined with the CESTPATH command, establishes a link to allow data to be transferred between the logical subsystems or storage controls.
You can determine whether a PPRC path is active by issuing the CQUERY command with the PATHS option to query the status of all PPRC paths established for a volume’s storage control.
