Creating Thin Image data pools

You can create Thin Image data pools using HDvM - SN. For information about the creation of HDP pools, see the Provisioning Guide.

NoteYou can only register volumes that you have not already registered as a pool-VOL.

You can add external and internal volumes to data pools.

NoteThere are limitations to adding external and internal volumes to data pools.
