8. The Specify Logical Drive-to-LUN Mapping window opens (Figure 4-62). This window
allows you to choose between mapping your created logical drive to the default group or to
“Map later using the Mappings View.” If you choose the Default mapping, then the physical
volume is mapped to the default host group and is available to any host zoned to the
DS5000 storage subsystem, so it is not the recommended choice if your DS5000 storage
subsystem supports more than a single partition.

9. Click Finish and the Creation Successful window opens. You are prompted about whether
you want to create another logical drive. Click No if you have finished creating logical
drives or want to finish at a later time.
10.The Completed window opens. The Mapping section presents the logical volume to a
desired host. Click OK to finish.
11.Repeat the same process for creating other arrays and logical drives.
If you left unconfigured capacity inside the array, you can later define another logical drive in
this array. Simply highlight this capacity, right-click, and choose Create Logical Drive. Follow
the steps that we previously outlined in this section, except for the selection of drives and
RAID level (because the array is already defined).
Important: Manually mapping logical drives to hosts prevents unwanted mapping and
is always the recommended choice.
