Storage system configuration with Thin Image and GAD
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.
Supported configurations
The following figure shows a supported storage system configuration with a
Thin Image pair using a GAD P-VOL.
