6.Set the composite group to Asynchronous mode.

#symrdf -cg MSCcg set mode async

7.Enable consistency protection to ensure data consistency on R2 side for the SRDF/Asynchronous devices in the composite group.

#symrdf -cg MSCcg enable

8.If the SRDF pairs are not in a consistent state at this point, initiate an establish command to synchronize the data on the R2 side from the R1 side. The device state will be SyncInProg until the consistent status is reached.

#symrdf -cg MSCcg establish

#symrdf -cg MSCcg query -rdfa
