Configuration errors occur when the configuration of the Primary and Secondary RVGs is not identical. Each data volume in the Primary RVG must have a corresponding data volume in the Secondary RVG of exactly the same size; otherwise, replication will not proceed. If a volume set is associated to the RDS, the configuration of the volume set must also match on the Primary and on the Secondary.
Errors in configuration are detected in two ways:
attachcommand fails and prints error messages indicating the problem. The problem is fixed by correcting the configuration error, and then retrying the attach.
config_errflag set. The problem is fixed by correcting the configuration error, and then resuming the RLINK.
