The list of volumes passed contain pairs which belong to different consistency groups in the scope of one single cluster.
TSM ACS handles for each operation only one consistency group per cluster at the same time. If the set of volumes in a backup or restore operation contain pairs that belong to different consistency group inside one single cluster, then the process of the operation will be stopped.
Process stopped.
If you added volumes to the production database or to the target set, ensure that they are not in any FlashCopy® relation.
