3. Use the following command to monitor the status of the RDF pair
state between the R1 and R2 devices:
# symrdf -cg cgoradb query
Once the column with the “RDF Pair STATE” shows the state as
“Synchronized” for all the devices, you can proceed to the next step.
4. Re-establish the BCV devices in the secondary Symmetrix as a
mirror of the standard device. From node 3 or node4:
# symmir -g dgoraA -full est
# symmir -g dgoraB -full est
Alternatively, from node1 or node2:
# symmir -g dgoraA -full est -rdf
# symmir -g dgoraB -full est -rdf
