Handling Link Preemption
For information about creating new links and link priority, see Chapter 6, “Using Inventory.”
If a path segment (part of one of your links) is preempted while the session is running, the preempted link
displays in red. You can try reconnecting the link by right-clicking it and selecting Retry.
To delete the links, right-click the links to delete and select Break Link.
You can add session links by switching to the link editor and dragging the link from one interface to a
second one.
Managing Session Resources
You can add resources, make them inactive, and remove them from ongoing sessions to maximize resource
allocation. The system scheduler is involved in committing any changes that affects resource allocation.
The following sub-sections describe how to manage session resources:
• Understanding Resource Representation
• Displaying Resource and Link Status
• Displaying Resource Instance Properties
• Adding Resource Instances
• Substitution Resource Instances
• Deactivating and Activating Resources
• Deleting Resources
Understanding Resource Representation
Managed Equipment are represented with a single icon. Virtual equipment can be represented as groups in
a single icon to facilitate the management of a larger set of resources; see Figure 9-29.
Figure 9-29 Session Example with 1 Virtual Group of 5 Resources and 1 Managed Resource
To interact with a Managed Equipment resource, perform the following steps:
1. Open a session editor; see the “Opening the Session Editor” section on page 9-8.
2. In the session editor, select the resource.
3. Right-click and select one of the operations for this resource.
