Learn About Using the Logical/Physical View

The    contains two panes: the Logical View and the Physical View.

About the Logical View

The Logical View, as shown in the following graphic, is one of two Logical/Physical View panes in the Array Management Window. The Logical View provides a tree-structured view of logical nodes. Click the plus or minus sign beside the node to expand or collapse the view of its child nodes.

The , or root node , has three types of child nodes, as shown in the following table.

Types of Virtual Disks

There are various types of virtual disks shown under the Disk Group node.

•    in an  state are represented by this icon in the Logical View. In the preceding graphic, Engineering is a .
•    are standard virtual disks participating in a mirror relationship in the primary role. Primary virtual disks in an Optimal state with a synchronized mirror relationship are represented by this icon in the Logical View. The remote  associated with the primary virtual disk is shown as a child node. In an Optimal state with a synchronized mirror relationship, the secondary virtual disk is represented by this icon . In the preceding graphic, Human Resources is a primary virtual disk, and the associated secondary virtual disk is Human Resources 2.
•  Secondary virtual disks are shown directly under the disk group node when the local storage array contains this virtual disk. In this case, the primary virtual disk is remote and is not shown. In the preceding graphic, Accounting is a local secondary virtual disk.
•    in an Optimal state are represented by this icon in the Logical View. In the preceding graphic, Mirror Repository 1 and Mirror Repository 2 are shown. One of these virtual disks is a resource for one of the  in the storage array, and the other virtual disk is a resource for the other RAID controller module.
•    in an Optimal state are represented by this icon in the Logical View. In the preceding graphic, the virtual disk is named Repository.
•   , represented in an Optimal state by this icon in the Logical View, are child nodes of their associated . In the preceding graphic, Snapshot 1 is a snapshot virtual disk of the source virtual disk Manufacturing.
•    are standard virtual disks participating in a  relationship that are used as the copy source for a . They accept  I/O requests and store application data. A source virtual disk can be a standard virtual disk, snapshot virtual disk, snapshot source virtual disk, or  primary virtual disk.
•    are standard virtual disks participating in a virtual disk copy relationship and contain a copy of the data from the source virtual disk. Target virtual disks are read-only and will not accept write requests. A target virtual disk can be made from a standard virtual disk, the source virtual disk of a snapshot virtual disk, or a Remote Virtual Disk Mirror primary virtual disk. The virtual disk copy overwrites any existing virtual disk data if an existing virtual disk is used as a target.

About the Physical View

The Physical View is the second pane of the Logical/Physical View. The Physical View performs the following functions:

• It provides a view of the physical components in a storage array, including their status
• It 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 RAID controller module. For example, if the RAID controller module has horizontal expansion enclosures, the software will show horizontal expansion enclosures in the Physical View.

RAID Controller Module Status

The status of each RAID controller module is indicated by an icon in the Physical View. The following table describes the various RAID controller module icons.

	Online, Active, Optimal
	Offline, Active
	Data Transfer Disabled
	Service Mode
	Slot Empty
	Needs Attention (if applicable for your hardware model)
	Suspended (if applicable for your hardware model)

Association

In the preceding Physical View example, the following conditions apply:

• The blue association dot shown beside RAID Controller Module A in the RAID Enclosure identifies the current owner of a selected virtual disk in the Logical View.
• The blue association dots underneath the  in Expansion Enclosure 1 identify the physical disks associated with a selected virtual disk in the Logical View.

Components Button

The Components button on each displayed enclosure shows the status of secondary components within the enclosure. For more information, see Viewing the Status of RAID Enclosure Components and Viewing the Status of Expansion Enclosure Components on the How To tab.

Expansion Enclosures

For each expansion enclosure attached to the storage array, a expansion enclosure is displayed in the Physical View. If your storage array contains mixed , a physical disk type icon is displayed on the left of the expansion enclosure to indicate the type of physical disks in the expansion enclosure. The following table describes the different physical disk type icons that might be displayed.

Important: Mixing different physical disk types within a single expansion enclosure is not permitted.
