Viewing Objects and Object Properties

VxVM provides the following views of objects and their properties:

“Tree and Grid View ”

The main window tree and grid view displays volumes, disks, file systems, and other objects on the system. The grid also displays a limited set of properties for listed objects.

“Disk View Window ”

The Disk View window displays a graphical view of disks, volumes, and other objects in a particular disk group.

“Volume View Window ”

The Volume Layout Details window displays a close-up graphical view of a single volume and its components (mirrors/plexes and subdisks).

“Volume to Disk Mapping Window ”

The Volume to Disk Mapping window shows the relationships between volumes and their underlying disks.

“Object Properties Window ”

The object Properties window contains detailed information about a specific object.

Tree and Grid View

The main window tree and grid view displays volumes, disks, file systems, and other objects on the system. The object tree is a hierarchical display of object groups. The grid is a tabular display of objects and a limited set of properties. VxVM constantly monitors objects on the system and makes appropriate changes to the tree and grid displays.

Disk Usage Legend

The disk usage legend is displayed at the bottom of the right pane; and shows how to interpret the colors with respect to Disk Usage (Normal Usage, High Usage, and Critical Usage).

Disk View Window

The Disk View window displays a graphical view of disks. It is dynamic, so the objects displayed in this window are automatically updated when their properties change. You can select objects or perform tasks on objects in the Disk View window.

The Disk View window can be accessed by clicking on a disk and selecting Actions > Disk View.

You can move the horizontal splitter to adjust the relative heights of both panes. To resize the volume and disk panes, place the pointer over the horizontal splitter and then press and hold the mouse button to drag the splitter to the desired position.

Using the Menu Bar

The menu bar at the top of the Disk View window contains the following menus:

File
The File menu enables you to:
- Access to the page setup menu

- Close the Disk View window
- Access the Properties window
- Display selected disks

Options
The Options menu provides you with the following selections:
- Refresh View
- Collapse—provides basic information for all disks in the view
- Expand—provides detailed information for all disks in the view
- Vol Details—basic volume information
- Full Volume Display—volume objects also display the volume size, free space, and state of the volume
- Projection—highlights associated objects

With the exception of Refresh View and Full Volume Display, these options are also available from the icons under the Disk View menu bar.

Action
The Action menu provides all the tasks available on the corresponding object in the main window.

Using the Toolbar

The toolbar at the top of the Disk View window has the following set of buttons:

Expand
The Expand button shows more detailed information about all disks in the Disk View, including subdisks and free space. This button displays objects in layout mode or detailed mode, depending on the previous mode.

Collapse
The Collapse button hides details for all disks in the Disk View. This button displays objects in layout mode or basic mode, depending on the previous mode.

Projection
The Projection button highlights objects associated with the selected subdisk or volume.
Projection shows the relationships between objects by highlighting objects that are related to or part of a specific object. When disks are in layout mode or detailed mode, clicking on a subdisk highlights the location of the subdisk on the corresponding disk.
Print
The Print button prints the properties of the selected object.

The toolbar handle is the thin bar next to the toolbar. You can use the toolbar handle to separate the toolbar from the window or move the toolbar to the bottom, side, or top of the window. To reposition the toolbar, press and hold the mouse button over the toolbar handle and drag the toolbar to its new location.

In the Disk View, you can move subdisks by dragging the subdisk icons to their new locations. You can drag a subdisk to another disk or a gap on the same disk. To move a subdisk, place the pointer over the subdisk and then press and hold the mouse button to drag the subdisk to another location.




	CAUTION: Moving subdisks reorganizes volume disk space and must be done with care.

The Disk View window displays plexes and subdisks that are associated with volumes. To view Volume Manager objects that are not associated with volumes (such as dissociated plexes), open the Dissociated Object View window (see “Dissociated Plex View Window ”).

Mapping Disks to Volumes

You can map a disk to the associated volume by bringing up both the Disk View and the Volume View (see “Volume View Window ”). When you click on the disk in the Disk View, the corresponding plex in the Volume View is highlighted.

Volume to Disk Mapping Window

The Figure 2-1 “Volume to Disk Mapping Window” displays a tabular view of volumes and their underlying disks. Volumes are listed in the top row of the table and disks are listed in the left column of the table. Each circle icon in the table indicates that part of the corresponding volume is located on the corresponding disk.

This window can also display details such as the subdisks and gaps (free space) on each disk. Each subdisk or gap is listed with its disk offset and length. When subdisks are shown, circles show the relationship between volumes and subdisks.

The Volume to Disk Mapping window is dynamic, so the contents of this window are automatically updated when objects are added, removed, or changed. For instructions on navigating the Volume to Disk Mapping window, see “Navigating the Volume to Disk Mapping Window”.

To display the Volume to Disk Mappng window, click on the disk group (in the main window grid) and then choose Actions > Disk/Volume Map.

The File menu displays volume and disk property information, or closes the window.

The View menu changes the way objects appear in the Volume to Disk Mapping window, and allows you to set up collection of statistics for the disk group.

The context-sensitive Actions menu allows you to perform tasks for a selected object. To access the popup menu for an object, right-click on the object.

The Volume to Disk Mapping window has a performance monitoring feature that ranks volume response time. When performance monitoring is turned on, the icons in the table change. The volumes with the slowest reads/writes are shown as red icons. Volumes with relatively slow response time are shown as yellow icons. All other volumes are shown as green icons.

Figure 2-1 “Volume to Disk Mapping Window” shows the relationships between volumes and disks.
