Not all storage system configurations are supported when sharing a Thin Image volume with a GAD volume.
When you create a Thin Image pair using a volume from a GAD pair, the server recognizes the GAD P-VOL and S-VOL as a single volume. If you create Thin Image pairs using both the P-VOL and S-VOL of a GAD pair, the server recognizes the GAD P-VOL and S-VOL as a single volume being paired with multiple volumes by Thin Image.
