After Enhanced Storage is installed, very little additonal configuration needs to be done. You must create state database replicas, then create any volumes (RAID 0, RAID 1, RAID 5, transactional, and soft partitions) you want. Finally, you will probably (depending on your situation) need to create file systems on the new volumes.
The fastest way to get started is to:
Click Volumes in the Navigation pane.
Choose Action->Add Volume, then follow the instructions within the wizard to add necessary state database replicas, volumes, and optionally also disk sets and hot spare pools.
Alternatively, you could explicitly create state database replicas, volumes, hot spare pools, and disk sets by choosing each type of object from the Navigation pane, then choosing Action->Add to add new objects of the chosen type.
