6.4.3. System Groups —

The System Groups page allows all RHN Management and Provisioning users to view the System Groups list. Only System Group Administrators and Satellite Administrators may perform the following additional tasks:
  1. Create system groups. (Refer to Section 6.4.3.1, “Creating Groups”.)
  2. Add systems to system groups. (Refer to Section 6.4.3.2, “Adding and Removing Systems in Groups”.)
  3. Remove systems from system groups. (Refer to Section 6.4.2.9, “System Details”.)
  4. Assign system group permissions to users. (Refer to Section 6.9, “Users — ”.)
The System Groups list displays all of your system groups.
The System Groups list contains several columns for each group:
  • Select — These checkboxes enable you to add systems in groups to the System Set Manager. To select groups, mark the appropriate checkboxes and click the Update button below the column. All systems in the selected groups are added to the System Set Manager. You can then use the System Set Manager to perform actions on them simultaneously. It is possible to select only those systems that are members of all of the selected groups, excluding those systems that belong only to one or some of the selected groups. To do so, select them and click the Work with Intersection button. To add all systems in all selected groups, select them and click the Work with Union button. Each system will show up once, regardless of the number of groups to which it belongs. Refer to Section 6.4.4, “System Set Manager — ” for details.
  • Updates — Shows which type of Errata Alerts are applicable to the group or confirms that it is up-to-date. Clicking on a group's status icon takes you to the Errata tab of its System Group Details page. Refer to Section 6.4.3.3, “System Group Details — ” for more information.
    The status icons call for differing degrees of attention:
    • — All systems within group are up-to-date
    • — Critical Errata available, update strongly recommended
    • — Updates available and recommended
  • Group Name — The name of the group as configured during its creation. The name should be explicit enough to easily differentiate between it and other groups. Clicking on the name of a group takes you to Details tab of its System Group Details page. Refer to Section 6.4.3.3, “System Group Details — ” for more information.
  • Systems — Total number of systems contained by the group. Clicking on the number takes you to the Systems tab of the System Group Details page for the group. Refer to Section 6.4.3.3, “System Group Details — ” for more information.
  • Use in SSM — Clicking the Use Group button in this column loads the group from that row and launches the System Set Manager immediately. Refer to Section 6.4.4, “System Set Manager — ” for more information.

6.4.3.1. Creating Groups

To add a new system group, click the create new group link at the top-right corner of the page. Type a name and description and click the Create Group button. Make sure you use a name that clearly sets this group apart from others. The new group will appear in the System Groups list.

6.4.3.2. Adding and Removing Systems in Groups

Systems can be added and removed from system groups in two places: the Target Systems tab of the System Group Details page and the Groups tab of the System Details page. The process is similar in both instances. Select the systems to be added or removed and click the Add Systems or Remove Systems button.

6.4.3.3. System Group Details —

At the top of each System Group Details page are two links: work with group and delete group. Clicking delete group deletes the System Group and should be used with caution. Clicking Work with Group functions similarly to the Use Group button from the System Groups list in that it loads the group's systems and launches the System Set Manager immediately. Refer to Section 6.4.4, “System Set Manager — ” for more information.
The System Group Details page is broken down into tabs:
6.4.3.3.1. System Group Details ⇒ Details —
Provides the group name and group description. To change this information, click Edit Group Properties, make your changes in the appropriate fields, and click the Modify Details button.
6.4.3.3.2. System Group Details ⇒ Systems —
Lists systems that are members of the system group. Clicking links within the table takes you to corresponding tabs within the System Details page for the associated system. To remove systems from the group, select the appropriate checkboxes and click the Remove from group button on the bottom of the page. Clicking it does not delete systems from RHN entirely. This is done through the System Set Manager or System Details pages. Refer to Section 6.4.4, “System Set Manager — ” or Section 6.4.2.9, “System Details”, respectively.
6.4.3.3.3. System Group Details ⇒ Target Systems —
Target Systems — Lists all systems in your organization. This tab enables you to add systems to the specified system group. Select the systems using the checkboxes to the left and click the Add Systems button on the bottom right-hand corner of the page.
6.4.3.3.4. System Group Details ⇒ Errata —
List of relevant Errata for systems in the system group. Clicking the Advisory takes you to the Details tab of the Errata Details page. (Refer to Section 6.5.2.2, “Errata Details” for more information.) Clicking the Affected Systems number lists all of the systems addressed by the Errata. To apply the Errata Updates in this list, select the systems and click the Apply Errata button.
6.4.3.3.5. System Group Details ⇒ Admins —
List of all organization users that have the ability to manage the system group. Satellite Administrators are clearly identified. System Group Administrators are marked with an asterisk (*). To change the system group's users, select and unselect the appropriate checkboxes and click the Update button.
6.4.3.3.6. System Group Details ⇒ Probes —
List all probes assigned to systems in the system group. The State shows the status of the probe. Click the individual System for details on the probe and to make changes to the probe configuration. Click the Probe to generate a customizable report on the monitoring.
