The Subsystem Management Window Logical/Physical View contains two panes: the Logical View and the Physical View.
About the Logical View
The Logical View, as shown in the following example, is one of two Logical/Physical View panes in the Subsystem Management Window. The Logical View provides a tree-structured view of logical nodes. Click on the plus or minus sign beside the node to expand or collapse the view of its child nodes.
The storage subsystem, or root node , has three types of child nodes.
Child Nodes of the Root Node
Description
Unconfigured Capacity
Represents any storage subsystem capacity that has not been configured into an array.
Missing Logical Drives
This placeholder node, represented by this icon in the Logical View, has child nodes that represent any missing logical drivesin the storage subsystem. Each missing logical drive is represented by this icon .
Array
An Array Node has two possible types of child nodes, as follows:
Child Nodes of the Array Node
Description
Logical Drive
Represents a configured and defined logical drive. There can be multiple Logical Drive nodes under an Array node. See Types of Logical Drives, below, for a description of these logical drives and there representative icons.
Free Capacity
Represents a region of capacity that can be used for creation of one or more new logical drives within the array. There can be multiple Free Capacity nodes under an Array Node.
Free Capacity nodes are represented by this icon in the Logical View.
Types of Logical Drives
There are various types of logical drives shown under the Array node.
Standard logical drivesin an Optimal state are represented by this icon in the Logical View. In the graphic above, Engineering is a standard logical drive.
Primary logical drivesare standard logical drives participating in a mirror relationship in the primary role. Primary logical drives in an Optimal state with a synchronized mirror relationship are represented by this icon in the Logical View. The remote secondary logical driveassociated with the primary logical drive is shown as a child node. In an Optimal state with a synchronized mirror relationship, the secondary logical drive is represented by this icon . In the graphic above, Human Resources is a primary logical drive and the associated secondary logical drive is Human Resources 2.
Secondary logical drives are shown directly under the array node when the local storage subsystem contains this logical drive. In this case the primary logical drive is remote and is not shown. In the graphic above, Accounting is a local secondary logical drive.
Mirror repository logical drivesin an Optimal state are represented by this icon in the Logical View. In the graphic above, Mirror Repository 1 and Mirror Repository 2 are shown. One of these logical drives is a resource for one of the controllers in the storage subsystem and the other logical drive is a resource for the other controller.
FlashCopy repository logical drivesin an Optimal state are represented by this icon in the Logical View. In the graphic above, the logical drive is named Repository.
FlashCopy logical drives, represented in an Optimal state by this icon in the Logical View, are child nodes of their associated base logical drive. In the graphic above, FlashCopy 1 is a FlashCopy logical drive of the base logical drive Manufacturing.
About the Physical View
The Physical View is the second pane of the Logical/Physical View. The Physical View:
Provides a view of the physical components in a storage subsystem, including their status
Shows the physical components associated with a selected node in the Logical View
Note: The orientation of the Physical View is determined by actual layout of the controller. For example, if the controller has horizontal drive enclosures, the software will show horizontal drive enclosures in the Physical View.
Association
In the example above:
The blue association dot shown beside Controller A in the Controller Enclosure identifies the current owner of a selected logical drive in the Logical View.
The blue association dots underneath the assigned drives in Drive Enclosure 1 identify the drives associated with a selected logical drive in the Logical View.
