Any version 110 (or greater) disk group (DG) can contain both CDS and non-CDS disks. However, only version 110 (or greater) disk groups composed entirely of CDS disks have the ability to be shared across platforms. Whether or not that ability has been enabled is a license-controlled attribute of the disk group (the cds attribute). Enabling that attribute causes a non-CDS disk group to become a CDS disk group.
Although a non-CDS disk group can contain a mixture of CDS and non-CDS disks having dissimilar private region alignment characteristics, its disk group alignment will still direct how all subdisks are created.
