4.4 Repository Item

Each storage repository configured within the environment is displayed as a repository navigation item within the Repositories navigation folder. These repository navigation items are labelled according to the repository name that is configured within Oracle VM Manager. If a name is not available or not configured properly within Oracle VM Manager, the repository UUID is allocated as the repository name. The structure of the navigation provided in the navigation tree is discussed in more detail in Section 4.2, “Summary”.

Clicking on a repository navigation item in the navigation tree allows you to access different perspectives in the management pane. Each perspective provides its own view of the repository within Oracle VM Manager. Most of the perspectives also include separate perspective toolbars that enable you to perform various configuration or management tasks specific to the view currently displayed within the management pane. A repository navigation item offers the following perspectives within the management pane:

4.4.1 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:

Description

Help

Displays context sensitive help.


This perspective includes the following information:

  • Repository Name: The configured name for the repository.

  • Ownership: The owner of the repository.

  • Path: The path to the file system that is used for the repository file system.

  • Share Path: The path to a subdirectory on the repository file system.

  • File System Size (GiB): The total size of the file system.

  • File System Used (GiB): The amount of file system that is in use.

  • Used (%): The amount of file system that is in use as a percentage.

  • Apparent Size (GiB): The apparent size in GiB. The apparent size is the total size of the entire repository.

    Note

    Oracle VM Manager uses a separate interval to collect the apparent size of the repository. That interval is longer than the interval at which other file system statistics are collected. For this reason, when changes to the contents of the repository file system occur, you might notice that it takes several minutes for the apparent size statistic to update after other file system statistics are updated.

  • Capacity (%): The percentage of the file system that is allocated. If the value is 100%, then all available disk space is allocated. If the value is greater than 100%, then the disk space is oversubscribed. For example, the repository contains several virtual disks that are sparsely allocated. If all of the virtual disks reach the maximum size, then the capacity exceeds the available disk space.

  • ID: The ID for the repository.

  • Description: The description provided for the repository when it was created or edited.

  • Presented to Servers: A list of the servers to which the repository has been presented.

4.4.2 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:

Description

Acknowledge

Acknowledge icon

Acknowledge a selected error event to clear the error and return the object to normal operations. Note that this option is only available for user acknowledgeable events.

Acknowledge All

Acknowledge All icon

Acknowledge all error events associated with an object to clear the errors and return the object to normal operations. Note that only user acknowledgeable events are cleared. This button is always clickable, even if there are no user acknowledgeable events. Clicking it when there are no user acknowledgeable events results in an error dialog.

Display Count

 

A drop-down menu that allows you to select the number of events that should be displayed in the management pane, while you are currently in this perspective.


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.
