  7. Configure the Storage Cluster environment with ETERNUS-B as the Primary Storage and ETERNUS-C as the Secondary Storage.

  8. Connect the fiber channel disconnected in step 2 to the CA port of ETERNUS-C and hard wire the connection with the business server.

  9. After confirming that the ETERNUS-B TFO group phase is "Normal", perform the Manual Failover, referring to "9.4.2.4 Manual Failover/Failback".

  10. Remove the fiber channel cable connected to the ETERNUS-B CA port.
