The Mappings View of the Subsystem Management Window contains two panes: the Topology View and the Defined Mappings View.

Note: Resize either pane by dragging the splitter bar, located between the two panes, to the right or to the left.

About the Topology View

The Topology View is one of two panes in the Mappings View of the Subsystem Management Window. The Topology View provides a tree-structured view of logical nodes related to storage partitions. Click on the plus or minus sign beside the node to expand or collapse the view.

Nodes in the Topology View

The storage subsystem, or root node , has four types of child nodes. Click on the pop-up glossary topic for a description of the node.

Child Nodes of the Root Node

Description of child nodes

Undefined Mappings

The Undefined Mappings Node has one possible type of child node, as follows:

Child Node of the Undefined Mappings Node

Description

Individual Undefined Mapping

Represents a logical drive with an undefined mapping. There can be multiple Logical Drive nodes under an Undefined Mappings node. The logical drive name is shown.

Default Group

Note: If the Storage Partitioning feature is disabled, all created logical drives are in the Default Group.

A Default Group Node has two possible types of child nodes, as follows:

Child Nodes of the Default Group Node

Description

Host Group

Defined host groups that are not participating in specific mappings are listed. This node can have host child nodes, which can have child host port nodes.

Host

Defined hosts that are not part of a specific host group (but are part of the Default Group) and are not participating in specific mappings are listed. This node can have child host port nodes.

Host Group

A Host Group Node has two possible types of child nodes, as follows:

Child Nodes of the Host Group Node

Description

Host

Defined hosts that belong to this defined host group are listed. This node can have child host port nodes.

Note: The host nodes that are child nodes of this host group can also participate in mappings specific to the individual host rather than the host group.

Host

A Host Node has two possible types of child nodes, as follows:

Child Nodes of the Host Node

Description

Host Ports

This placeholder node has child nodes that represent all host ports (a single ports on a host adapter) associated with this host.

Storage Partition Icon

The storage partition icon , when present in the Topology View, indicates a storage partition has been defined for a the Default Group, a host group or a host. This icon is also displayed in the status bar of the Mappings View window when storage partitions has been defined.

About the Defined Mappings View

The Defined Mappings View displays the mappings associated with a node selected in the Topology View.

The information shown below is displayed for a selected node.

Column Name

Description

Logical Drive Name

The user-supplied logical drive name.

The factory-configured Access Logical Drive will also be displayed in this column.

An Access Logical Drive mapping is NOT required for directly managed storage subsystem and may deleted from the Defined Mappings pane. For more information, see Deleting a Host Port, Host, Host Group or Logical Drive Mapping.

Accessible By

Displays the topological element (Default Group, a defined host group or a defined host) that has been granted access to the logical drive in the mapping.

LUN

The LUN number assigned to the particular logical drive, that the host(s) use to access the logical drive.

Logical Drive Capacity

Displays the logical drive capacity in units of GB.

Type

Indicates whether the logical drive is a standard or FlashCopy logical drive.

The information displayed in the Defined Mappings View varies according to what node you select in the Topology View.

If you select...

Then the Defined Mappings View displays...

Root (storage subsystem) node

All defined mappings.

Default Group Node or any of its child nodes

All mappings that are currently defined for the Default Group (if any).

Host Group Node (outside of Default Group)

All mappings that are currently defined for the Host Group.

Host Node that is a child node of a Host Group Node

All mappings that are currently defined for the Host Group, plus any mappings specifically defined for a particular host.

Host Ports Node or individual host port node outside of the Default Group

All mappings that are currently defined for the host port's associated host.
