Note: When you run the logical drives wizard, (8.3.3, “Create Logical Drives” on
page 161), it prompts you at the end, if you want to map the generated drive now
(Figure 8-49 on page 166). If you do map the drive at this point, the storage partitioning is
also created then. However, if you prefer to do it at a later point of time, or if you had not yet
configured all the hosts and host groups, you can add storage partitions as shown in this
section.
