282 IBM System Storage DS3500: Introduction and Implementation Guide
11.1 Mappings tab
The Mappings tab contains the Topology pane and the Defined Mappings pane. In the
Topology pane, you can define the host groups, hosts, and host ports. The Topology pane
shows a tree structured view of the logical nodes related to storage partitions in the storage
subsystem. The Defined Mappings pane shows the mappings (Logical Drives) that are
associated with a selected host group or host in the Topology pane. You can also change the
mappings to grant logical drive access to host groups or hosts, and create storage partitions.
The overall process of defining the storage partitions is described in this chapter according to
the below topics:
11.2, “Defining Host” on page 283
11.3, “Defining Storage Partitioning” on page 292
11.4, “Defining Host Group” on page 295
11.5, “Manage Host Port Identifiers” on page 297
11.6, “Define Additional Mapping” on page 298
11.7, “View Unassociated Ports” on page 300
11.8, “Move, Remove and Rename Host” on page 300
11.9, “Change Host Operating System” on page 301
11.10, “Change and Remove Mapping” on page 302
To start with mapping, select the Mappings tab in DS Storage Manger subsystem window. If
you have not defined any storage partitions yet, the Mapping Start-Up Help window (shown in
Figure 11-1) opens. The information in the window advises you to only create host groups if
your plan includes sharing logical volumes across different hosts, normally a cluster.
