8.2 Setting Up a Personalized List of Clusters to Manage

The My Clusters page in the Clusters plug-in for iManager allows each cluster administrator to set up a personalized list of clusters to manage. This allows an administrator to view at a glance the status of the specified clusters. The list persists between the administrator's logins to the same iManager server.

Your personalized list of clusters and display preferences are saved on the iManager server in the following location:

/var/opt/novell/iManager/nps/WEB-INF/config/NDS<tree_name>-<user_name_and_context_without_dots>/ncs.xml

For example, for tree AVALONTREE and user admin.novell, the file path is:

/var/opt/novell/iManager/nps/WEB-INF/config/NDSAVALONTREE-adminnovell/ncs.xml

The following sections describe how manage the list of clusters and to personalize the display.

8.2.1 Adding Clusters to Your My Clusters List

  1. Log in to iManager as a cluster administrator.

  2. In Roles and Tasks, select Clusters > My Clusters.

    The list is initially empty.

  3. Click Add to open the eDirectory browser pop-up window.

  4. Browse the tree where you are currently logged in to locate and select one or more Cluster objects, then click OK.

    Newly selected clusters are added to your personalized list.

  5. (Optional) Personalize the display as described in Section 8.2.3, Personalizing the My Clusters Display.

8.2.2 Viewing Information about Clusters in Your My Clusters List

  1. Log in to iManager as a cluster administrator.

  2. In Roles and Tasks, select Clusters > My Clusters.

    The My Clusters page displays your personalized list of clusters in the tree.

  3. View the Status icon next to a Cluster object to understand the current overall state of the cluster.

8.2.3 Personalizing the My Clusters Display

The My Clusters page provides menus in the column headings that allow you to personalize the display. You can sort the entries, modify the columns, or filter the entries.

  1. Log in to iManager as a cluster administrator.

  2. In Roles and Tasks, select Clusters > My Clusters.

  3. If the list is empty, you must add at least one cluster in order to be able to personalize the display. Select Add, browse to select the Cluster object, then click OK.

  4. Select Refresh, then choose a refresh rate that is long enough to allow you to view all items in the list.

  5. Click or mouse-over a column heading to activate its options, then click the arrow to access the menu for that column.

  6. Perform one of the available actions when you access the column’s menu. Some actions are not available for all fields.

    • Sort: Select Sort Ascending (A to Z) or Sort Descending (Z to A) to specify the preferred sort order. Cluster objects are sorted based on values in the selected column. Numbers are treated as text values and are sorted alphabetically, not numerically.

    • Columns: Select Columns to display the parameters, select or deselect a parameter’s check box to add or remove the column, then press Enter to apply the changes. The parameters are described in Step 4 in Section 9.17, Viewing the Cluster Node Properties.

    • Filter: Specify a filter to display only the Cluster objects with values that match.

      To add or modify a column’s filter, select Filter, place the cursor in the Filter field, type the desired filter text, then press Enter to apply the filter. If a cluster’s parameter value matches the specified filter, the Cluster object and its information are displayed.

      To remove a column’s filter, select Filter, place the cursor in the Filter field, delete the filter text, then press Enter to refresh the display. The filter no longer applies for that column.

8.2.4 Removing Clusters from a My Clusters List

    The My Clusters page displays your personalized list of clusters in the tree that you want to manage.

  3. Select the check box next to the cluster that you want to remove from your personalized list, then click Remove.

    The cluster is removed from your personalized list. This action does not delete the Cluster object or related objects.
