Figure 6.8. System Group List

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.
Status — 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.
