One of the selected volumes is configured to use a Consistent Replay Profile when taking Replays.
This allows the volume's Replays to remain consistent with the Replays of other volumes using the same Replay Profile.
In order to maintain consistency, it is recommended that you take Replays for all of the volumes in the consistency group at the same time.
To take Replays for all volumes in the consistency group, select All Volumes in Each Consistency Group.
To take a Replay for only the selected volume, select Only Selected Volumes.
