When trying to add volumes to the RDS, sometimes the volume names may not appear in the Add Volumes dialog box.

The reason for this is that the volume may have a Dirty Region Log (DRL) associated with it or the volume created may be a software RAID 5 volume or it may be missing. None of these volumes can be used for replication. A replicated volume can have only DCM logs associated with it. Similarly, a volume with a DCM log cannot be used as a Replicator Log.

To find out the type of the log associated with the volume that you want to add, click on the volume name in the tree view. The right panel of the VEA displays the volume properties. Click the logs tab to see the type of log associated with the volume.

Select the volume and right-click. Select the Log > Remove option from the menu that appears, to remove all the DRL logs. Now you can add the volume to the RDS.
