this is the only instance of the resource. (Removing all instances of a resource is the equivalent of
destroying the resource.)
To remove a resource from a group, do the following:
1 Select the parent group in the Component Tree to display the group in the Resource Details window.
2 Select the Children tab to display the resources that are children of the group.
3 Select the resource you want to remove.
4 Click the Remove button at the bottom of the window.
5 To save your changes to the EPICenter database, click the Save button at the bottom of the Grouping
Manager window.
If you attempt to begin a different operation or leave the Grouping Manager applet without saving,
the Grouping Manager prompts you to save your changes. However, you can add and remove
children and attributes to the group you have selected in multiple operations before you save.
Click the Cancel button at the bottom of the window to cancel the changes you have made to this
group.
Note that you can also remove resources by locating them using the Find function, and removing them
using the search results list. See
“Searching for a Resource” on page 238 for more information on the
Find function.
Removing a resource from all groups of which it is a member is the equivalent of destroying the
resource.
Adding Relationships to a Resource
Individual resources cannot have children. However, certain types of resources (Hosts, Users, or Ports)
can have relationships. Devices cannot have either relationships or children.
For example, a Host may have a relationship with a User, which indicates that the User is associated
with the IP address of that Host. A Host may also have a relationship with a port, indicating that the
host communicates over that port.
These relationships may be used by the Policy Manager applet to create low-level QoS policy rules
based on named higher-level objects such as users and hosts. Relationships can be created between the
following:
●
Hosts and Users
●
Hosts and Ports
●
Users and Ports
These relationships are always reciprocal: when you create a relationship between two resources, it is
added simultaneously to both resources.
1 In the Component Tree, select the resource to which you want to add a relationship, so that it is
displayed in the Resource Details view.
2 Click the tab labeled Relationships to display the list of children belonging to this group.
3 Click the Add button at the bottom of the list of Children to display the Add Relationship to Group
pop-up dialog, as shown in Figure 110 .
