The Mappings tab in the Subsystem Management Window (SMW) contains two panes: the Topology pane and the Defined Mappings pane.
Note:
You can resize either pane by dragging the splitter bar, located between the two panes, to the right or to the left.The Topology pane shows a tree-structured view of logical nodes related to . Click the plus (+) sign or the minus (-) sign adjacent to a node to expand or collapse the view. You can right-click a node to open a pop-up menu that contains the applicable actions for that node.
The , or the root node, has four types of child nodes.
Child Nodes of the Root Node | Description of the Child Nodes |
---|---|
Undefined Mappings |
The Undefined Mappings node has one type of child node. Individual Undefined Mapping – Represents a with an undefined mapping. Multiple Logical Drive nodes can exist under an . |
Note – If the Storage Partitioning premium feature is disabled, all of the created logical drives are in the Default Group. A Default Group node has two types of child nodes:
|
|
Host Group |
A Host Group node has one type of child node. 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 one type of child node. Host Ports – This node has child nodes that represent all of the host ports or single ports on a host adapter that are associated with this host. |
The Storage Partition icon, when present in the Topology pane, indicates that a storage partition has been defined for the Default Group, a host group, or a host. This icon also appears in the status bar when storage partitions have been defined.
The Defined Mappings pane shows the mappings that are associated with a node selected in the Topology pane.
This information appears for a selected node.
Column Name | Description |
---|---|
Logical Drive Name |
The user-supplied logical drive name. The factory-configured also appears in this column. Note – An access logical drive mapping is not required for storage subsystem with an connection and might be removed. |
Accessible By | Shows the 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 assigned to the specific logical drive that the host or hosts use to access the logical drive. |
Logical Drive Capacity | The logical drive capacity in units of GB. |
Type | The type of logical drive: standard logical drive or flashcopy logical drive. |
You can right-click a logical drive name in the Mappings pane to open a pop-up menu. The pop-up menu contains options to change and remove the mappings.
The information shown in the Defined Mappings pane varies according to what node you select in the Topology pane, as shown in this table.
Node Selected | Information That Appears in the Defined Mappings Pane |
---|---|
Root (storage subsystem) node | All defined mappings. |
Default Group node or any child node of the Default Group | 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 specific host. |
HBA Host Ports node or individual host port node outside of the Default Group | All mappings that are currently defined for the HBA host port’s associated host. |
