Not all snapshot group configurations are supported when sharing a Thin Image Advanced volume with a GAD volume.
Pairs in a Thin Image Advanced snapshot group must be in the same storage system. Therefore, if a GAD P-VOL and S-VOL are each used in Thin Image Advanced pairs, the Thin Image Advanced pairs cannot be registered to the same snapshot group.
