You can use a GAD P-VOL or S-VOL as a Thin Image (HTI) P-VOL.

You can create up to 1,024 Thin Image pairs using a GAD P-VOL, and up to 1,024 Thin Image pairs using a GAD S-VOL.

Because the server recognizes the GAD pair as one volume, it sees the volume as paired with 2,048 HTI volumes.

  • Pairs in an HTI consistency group and snapshot group must reside in the same storage system. Because of this, the HTI pairs that are associated with both the GAD P-VOL and S-VOL cannot be registered to the same consistency group or snapshot group.
  • When you use GAD pair volumes to create a Thin Image pair, specify the physical LDEV ID, not the virtual LDEV ID.
