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:
ň° 11.2, âDefining Hostâ on page 283
ň° 11.3, âDefining Storage Partitioningâ on page 292
ň° 11.4, âDefining Host Groupâ on page 295
ň° 11.5, âManage Host Port Identifiersâ on page 297
ň° 11.6, âDefine Additional Mappingâ on page 298
ň° 11.7, âView Unassociated Portsâ on page 300
ň° 11.8, âMove, Remove and Rename Hostâ on page 300
ň° 11.9, âChange Host Operating Systemâ on page 301
ň° 11.10, âChange and Remove Mappingâ 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.
