1.10 Using the Tabs

Each tab defines different objects and functional areas of operations that can be performed in Oracle VM Manager. When you select a tab the default management pane for that tab is displayed. The management pane change depending on the selected object in the navigation tree and the Perspective selected in the drop-down list in the management pane toolbar. The tabs in the Oracle VM Manager Web Interface are:

  • Chapter 2, Health Tab: to monitor the overall health and status of your virtualization environment and to view historical statistics such as memory and CPU usage.

  • Chapter 3, Servers and VMs Tab: to discover Oracle VM Servers, create and manage server pools and virtual machines, assign Oracle VM Servers to server pools, and create and configure virtual machines in server pools.

  • Chapter 4, Repositories Tab: to create and configure storage repositories and their content; virtual appliances, VM templates, ISO files, virtual disks and virtual machine configuration files.

  • Chapter 5, Networking Tab: to manage networks and their functions in your environment, create, edit and delete networks and VLAN groups, and create virtual NICs which can be used by virtual machines.

  • Chapter 6, Storage Tab: to manage, discover and edit file servers and SAN servers (storage arrays), physical disks, access groups and volume groups.

  • Chapter 7, Reports and Resources Tab: to manage tags which can be used to identify and group objects within Oracle VM Manager, and to configure server update repositories for updates of the Oracle VM Servers being managed by Oracle VM Manager. This tab also contains preferences that control certain user interface behaviors.

  • Chapter 8, Jobs Tab: to get a global view on jobs, to evaluate information on jobs completed or aborted, or to cancel a job in progress.

A Getting Started tab is also available if the Getting Started panel is displayed. This tab is described in more detail in Section 1.10.1, “Getting Started Tab”.

The order of the tabs is largely determined by frequency of use once your environment is completely configured. It is not indicative of the order in which you should attempt to configure the different elements within your environment. For an insight into the typical order in which configuration tasks should be performed for a fresh installation please refer to the information provided in the Getting Started tab, or to the Oracle VM Manager Getting Started Guide.

1.10.1 Getting Started Tab

When you first log in to the Oracle VM Manager Web Interface the Getting Started tab is displayed on the right side of the management pane. The Getting Started tab contains a tutorial that describes how to get started with Oracle VM Manager, and walks you through discovering Oracle VM Servers, registering storage, setting up networking, setting up a storage repository and importing resources into it, creating a server pool and creating virtual machines. To show or hide the tutorial, click the arrow to the right of the management pane.

Figure 1.2, “Getting Started tab” shows the Getting Started tab.


The information displayed in this tab is based on the content provided in the Oracle VM Manager Getting Started Guide.

1.10.2 Subtabs

On some tabs, links are shown at the top of the tab. These links are referred to as subtabs. Each subtab displays its own management pane. Subtabs are usually used when no navigation pane is shown, and serve a similar purpose to perspectives. Unlike perspectives, however, they do not display content about related object types, but are specific to a single configuration or management view within the Oracle VM Manager Web Interface. For example, subtabs are used on the Tools and Resources tab to distinguish between the configuration options available for different elements within Oracle VM Manager: Tags, Server Update Groups and Preferences. Each of these elements is self-contained and bears no specific relationship to the other.

1.10.3 Navigation Pane

Many of the views rendered for the different tabs available in the Oracle VM Manager Web Interface include a navigation pane, situated on the left hand side of the screen. The navigation pane is mostly used to organize objects that have a grouped relationships within Oracle VM Manager. These relationships are exposed in the form of a navigation tree.

The navigation tree shows the relationship between managed objects. These objects are both physical and virtual, and include Oracle VM Servers, server pools, virtual machines and so on, created using Oracle VM Manager. For example, the relationships between server pools, Oracle VM Servers, and the virtual machines hosted on those Oracle VM Servers. The navigation tree presents each object type as a node. If an object type contains child elements, it is possible to expand the node to view the elements that it contains. In the navigation tree presented on the Servers and VMs tab, there is a parent object called Server Pools. If you have already defined a server pool within your environment, this node can be expanded to show the server pools that you have already defined. Since each server pool must contain one or more servers, the individual server pool entries in the navigation tree are also displayed as expandable nodes. By expanding any of these nodes it is possible to see a list of each server within the server pool.

For each item in the hierarchy of the navigation tree, a different view is displayed in the management pane. The content of the management pane changes, depending on the object you select in the navigation tree. This view can often be changed by selecting a particular perspective from the Section 1.10.4, “Perspectives” drop-down. Therefore, if you wish to see the virtual machines that are running on a particular server within a server pool, on the Servers and VMs tab you would expand the Server Pools node, expand the server pool entry that you are interested in and select the server that you wish to view. Finally, in the management pane, select the Virtual Machines perspective.

Note

The icons for objects in the Navigation Tree may vary depending on the object's event status. Usually the same icon is used but an event anomaly is highlighted using an overlay applied to the original icon. See Section 1.11, “Object Icon Colors” for more information.

1.10.4 Perspectives

If the tab that you are viewing includes a navigation pane, it is more than likely that there are numerous perspectives associated with the item selected in the navigation tree. These perspectives are different views of information associated with each object stored within Oracle VM Manager. The perspectives are listed in a drop-down menu located in the toolbar at the top of the management pane. By selecting a particular perspective from the menu, the data in the management pane is updated to show the information relevant to the selected perspective. Furthermore, the perspective toolbar is updated to provide management and configuration options that are specific to the perspective that you are viewing.

1.10.4.1 Info Perspective

The Info perspective is common to many elements within the Oracle VM Manager Web Interface. This perspective always shows the individually configured parameters for an item that is currently selected in the navigation tree. Some of these configured parameters may be automatically populated through a discovery process, while others may have been configured manually during the creation of the object that is selected.

The Info perspective or dialog contains a perspective toolbar with the following options:

1.10.4.2 Events Perspective

The Events perspective is common to many elements within the Oracle VM Manager Web Interface. The Events perspective generally appears as an option within the Perspectives drop-down menu on the management pane of tabs that include a navigation tree. In this case, the Events perspective displays events specific to the item selected in the navigation tree and presents these in the management pane.

The Events perspective may also appear within a dialog that is triggered from a Display Selected Events... Display Selected Events... icon perspective toolbar option. In this case, the Events perspective dialog displays events specific to one or more elements selected in the management pane.

If an object has an error event associated with it you must acknowledge the event to clear the error and return the object to normal operations. For example, this can occur if an Oracle VM Server or virtual machine appear as Stopped (Error) in the status. The object in error is flagged with a red icon in the navigation tree. Oracle VM Servers, virtual machines, repositories and storage objects can have error events associated with them.

Since Oracle VM Manager attempts to resolve issues automatically as much as possible, not all events can be acknowledged by a user within the Oracle VM Manager Web Interface. Therefore, a flag is set for events that are user acknowledgeable. If an event does not have this flag set, you are unable to acknowledge it, since it is handled internally by Oracle VM Manager.

The Events perspective or dialog contains a table with the following columns of information for each event:

  • Severity: The severity level assigned to the event.

  • Timestamp: The date and time that the event occurred.

  • Modify Time: The last recorded date and time that the event was modified.

  • Type: The type of event according to Oracle VM Manager's event categorization model.

  • Summary: A summary description of the event.

  • Acknowledged: Whether an error event has been acknowledged.

  • User Acknowledgeable: Whether or not an event can be acknowledged by the user.

Event Descriptions

An arrow displays next to each event in the table. Click the arrow to expand and view the Description section that provides additional details for the event.

The Events perspective or dialog contains a perspective toolbar with the following options:

Acknowledging Events/Errors

If an object has an error event associated with it you must acknowledge the event to clear the error and return the object to normal operations. For example, this can occur if an Oracle VM Server or virtual machine appear as Stopped (Error) in the status. The object in error is flagged with a red icon in the navigation tree. Oracle VM Servers, virtual machines, repositories and storage objects can have error events associated with them. The following procedures show you how to clear errors and return the object to normal operations.

To acknowledge Oracle VM Server error events:

  1. Click the Servers and VMs tab.

  2. Select the Oracle VM Server in the navigation tree.

  3. Select Events from the Perspective drop-down list in the management pane.

  4. Select the user acknowledgeable error event and click Acknowledge Acknowledge icon , or click Acknowledge All Acknowledge All icon to clear all user acknowledgeable errors.

To acknowledge virtual machine error events:

  1. Click the Servers and VMs tab.

  2. Select the server pool, or Oracle VM Server on which the virtual machine resides in the navigation tree.

  3. Select Virtual Machines from the Perspective drop-down list in the management pane.

  4. Select the virtual machine in the management pane table. Click Display Selected VM Events... Display Selected VM Events... icon .

  5. The Events dialog box is displayed. Select the user acknowledgeable error event and click Acknowledge Acknowledge icon , or click Acknowledge All Acknowledge All icon to clear all user acknowledgeable errors. Click Close.

To acknowledge storage repository error events:

  1. Click the Repositories tab.

  2. Select the repository in the navigation tree.

  3. Select Events from the Perspective drop-down list in the management pane.

  4. Select the error event and click Acknowledge Acknowledge icon , or click Acknowledge All Acknowledge All icon to clear all errors.

To acknowledge storage error events:

  1. Click the Storage tab.

  2. Select File Servers, SAN Servers, or a storage server in the navigation tree.

  3. Select Events from the Perspective drop-down list in the management pane.

  4. Select the user acknowledgeable error event and click Acknowledge Acknowledge icon , or click Acknowledge All Acknowledge All icon to clear all user acknowledgeable errors.

1.10.5 Toolbars

One or more toolbars may be displayed on a tab, depending on the tab, subtab or perspective that you are viewing. If a navigation pane is displayed, a toolbar is frequently displayed at the top of the navigation pane, referred to as the navigation pane toolbar. When viewing different perspectives a toolbar is positioned at the top of the management pane. This toolbar is called the perspective toolbar.

The toolbars are used to perform specific actions. Depending on the selected tab, the icons in the toolbars change. Furthermore, the icons in the perspective toolbar change depending on the perspective selected. Therefore, the toolbar options are context-sensitive and change depending on the part of the user interface that you are currently viewing. Many of the toolbar options are also available as right-click menu options.

In most cases, clicking on a toolbar icon results in the display of a dialog or wizard to guide you through the configuration or management task selected. The icons for each toolbar available on each tab and perspective within the user interface are summarized for each tab view throughout this guide.

1.10.6 Management Pane

The management pane is usually, but not always, presented in table format. Objects or elements are listed in rows, and information or fields of data related to an object or element is separated into columns. In some cases information in the management pane may be simply presented as informational content listed in a form-like presentation.

Where the information in the management pane is presented as a table, it is often possible to sort the data in the table in ascending or descending format according to the different columns available. This is indicated on columns supporting sort functionality through the display of up and down arrow icons, which appear on mouse roll-over. Clicking on the up arrow icon for a column sorts in ascending order, while clicking on the down arrow icon sorts in descending order. Columns in a tabular view can be resized or rearranged through drag-and-drop style behavior.

A View menu that appears alongside the drop-down Perspectives menu at the top of the management pane provides alternative mechanisms to change sort order, the order of the fields presented in each column and to control which columns are displayed within a view.

Where additional information about an object or element is available, an additional expansion arrow is provided as a link alongside the item, usually on the left-hand side of a row when the data is presented in tabular format. Clicking on the expansion arrow expands the view for the selected element to display further information. Where this information is categorized according to related sub-elements, the expanded view may display tabs for the content related to each sub-element. Clicking through each of these tabs exposes the information related to each sub-element.
