You can create Thin Image (HTI) pairs using pair volumes for other replication software applications, such as ShadowImage and TrueCopy. You can also create Thin Image pairs using volumes to which you define attributes using Data Retention Utility or CCI even when you use HDvM - SN.

You can share Thin Image volumes with the following software application volumes:

Data Retention Utility (VSP 5000 series)
Volume Migration V2
ShadowImage (SI)
TrueCopy (TC)
Universal Replicator (UR)
Global-active device (GAD)

The following table shows when you can share Thin Image pair volumes with other software application volumes. If a volume that you share with a Thin Image volume is shown in the table, the pair status determines whether you can perform tasks. If the S-VOL is not assigned to snapshot data, you cannot share Thin Image volumes with other software applications, because the S-VOL does not exist.

Note: For node or leaf volumes, see the Used as an HTI S-VOL column instead of the Used as an HTI P-VOL column.

If you use HDvM - SN to share the volume with other software applications, the pair status determines whether you can share the volume. To share the volume with other software applications, you must use CCI. You cannot use Quick Restore. Use the Data Retention Utility (VSP 5000 series) to set this attribute. CCI is required to set this attribute. For setting the attribute, use the raidvchkset -vg command. Use the Data Retention Utility (VSP 5000 series) or use the raidvchkdsp　-v gfalg command to confirm whether this attribute is set to volume. Can be shared if the pair is cascaded or has the clone attribute. Can be set on an S-VOL of a cascaded pair or a clone attribute pair. Note that only the clone attribute enables capacity saving.
