Before registering a V-VOL, you may need to edit the control unit’s (CU) SSID, which you use to create new LDEVs. Use the
Change SSIDs window to edit a V-VOL’s SSID.
Depending on the types of pairs with which you are working, there are two options for creating a V-VOL for a Thin Image S-VOL. For pairs with the snapshot attribute (snapshot pairs) for which the cascade attribute is enabled (cascaded pairs) or for clone pairs, create a DP-VOL. You can use a non-cascaded snapshot tree (using only root volumes and leaf volumes) even when you create snapshot pairs that are cascaded. For information about creating a DP-VOL, see the Provisioning Guide for your storage system. For snapshot pairs for which the cascade attribute is disabled, create a Thin Image V-VOL.
