To View Managed Hosts

Sun Update Connection – Enterprise provides a hierarchical view of the inventory of all managed hosts. An inventory is a list of components that are installed on a managed host.

This view includes a brief description of the information shown for each host. You can also perform a procedure to manipulate the views.

Choose Inventory from the View menu to open the Inventory panel.

In the Hosts list, view the data of the managed hosts whose agents have registered with the system dependency server.

Expand the All Hosts group and a distribution subgroup to view the list of managed hosts.

Information about each managed host appears in the following columns:
- Distro – Linux distribution version or Solaris release that is installed on the managed host
- Arch – Hardware architecture of the managed host
- IP Address – IP address of the managed host
- Register Time – Date and time at which the agent registered with the dependency manager
- Last Inventory update – Date and time that the host inventory was last updated to the console

Select a managed host from the list to view information about it.

When no host is selected, you can browse the Components list to see what is available in the knowledge base for installation. This information pertains only to the distribution selected in the drop-down list in the tool bar.
- To see the Components list of a different distribution, change the selection of the tool bar drop-down list.
- To see which of the knowledge base components are installed on a specific host or hosts, select one or more hosts or groups from the Hosts list. The components installed on the selected hosts are marked as Installed on the Components list.
- To see only the installed inventory of hosts, select the hosts. Then, choose Show Installed from the Components menu.
  
  The Components list displays only the inventory of the selected hosts.

To Save the Inventory of a Host

Sun Update Connection – Enterprise provides a rollback feature. You can restore a managed host to a previous inventory, either full or filtered, as needed. The software automatically saves host inventories before executing a job to ensure that rollback is possible. You can also save inventories manually and give them meaningful names. Using such names makes it easier for you to choose the particular configuration to use.

From the Hosts list, right-click a host or a group and choose Save Inventory.

The Save Inventory window opens.

(Optional) Specify the name of the saved inventory.

The default file name uses this format name_yymmdd_hhmmss.

name is either the name of a managed host or a group. yymmdd represents the date as a two-digit year, two-digit month, and two-digit day. hhmmss represents the time as a two-digit hour, two-digit minute, and two-digit second.

Click OK.

The host inventory is saved and the Save Inventory window closes.

If you selected a group, an inventory is saved for each managed host in the group.

View a list of saved inventories in the Inventory Comparison window.

Right-click a managed host or group in the Hosts list, and then choose Compare Inventories.

Expand one of the Inventory drop-down lists to see the list of saved inventories for the selected host or group.
