How do I manage SRDF devices using storage groups? If I have a storage group with a subset of RDF devices, can RDF commands be run against the entire storage group? Would the best practice be to have dedicated storage groups that only contain RDF devices? Can the RDF pairs be established using just a storage group or does a map file need to be created to initialize the pairs? Has RDFG creation changed in the VMAX3?
