Just suspend and movepair. The delete/createpair operations are carried out in the maintenance RDFG.  1. No, it can be done in the SRDF/A RDFG, but i am proposing that it it is done in the maintenance RDFG. 2.If you are using a maintenance RDFG, the suspend/movepair is done on the SRDF/A RDFG and the deletepair is done in the maintenance RDFG. 3. The suspend /deletepair does not affect the consistency of the devices running in SRDF/A mode. Certain query  commands can show an overall inconsistent state for the SRDF/A RDFG though. This is another reason to use the maintenance group as it minimises the time the RDFG is reported as inconsistent due to device maintenance activities. 4. Deletepair should not need cons_exempt as it is already in that state from the suspend. 5. Suspend is fine. The device should have stopped being used prior to this work and as a result of the suspend, no invalid tracks should build up due to host writes to the R1 device.
Please provide information regarding deletepair in SRDF/A. I need to delete few device pairs from a running RDF group.  I have read few discussions on the same in ECN and have found two ways of doing it and am not sure which one is most appropriate?  1st Method: Create a new RDF group with the -f containing the devices to be removed and then do a movepair from the running RDF group to the new RDF group. Later do, suspend and deletepair with the new RDF group.  Or 2nd Method: Just have two files with one file containing the devices to be removed and the second file having the devices which need to continue to stay. Then perform suspend and deletepair on the file containing the devices to be removed. At the end, just to ensure that consistency is maintained on the devices which need to stay, perform set mode async and enable consistency on them. In this second scenario, all these operations have the same RDF group all the time. Does this not affect the RDF group in any way?  Also, the command just prior to deletepair, should be suspend or set mode acp_disk
