* The SI pair status must be "PSUS" during the period between when Thin Image Advanced directs storing snapshot data for a consistency group, and when the status of all pairs in the consistency group is changed to "PSUS". If the SI pair status changes to a status other than "PSUS" while Thin Image Advanced is storing snapshot data for the consistency group, consistency of the snapshot data cannot be guaranteed. |

Thin Image Advanced S-VOLs share the data in the P-VOL. You cannot Quick Restore in ShadowImage, which replaces the data in the ShadowImage P-VOL and S-VOL.
To share Thin Image Advanced volumes with ShadowImage if Thin Image Advanced is using the MU numbers 0 to 2:
- Delete the Thin Image Advanced pair of the MU number 0 to 2.
- Create the ShadowImage pairs and Thin Image Advanced pairs.
