You can use HP SUM to inventory and deploy software to the members of an iLO Federation group. Communication with the group members is facilitated by a node in the group that is called the interface iLO. This node is available with iLO 4 firmware version 1.40 and later. For more information about iLO Federation, see the HP iLO Federation User Guide, available at http://www.hp.com/support/ilo4_federation_ug_en.

When you log in to HP SUM, it automatically searches for iLO Federation groups on your connected networks. HP SUM searches each group and displays the nodes that respond to the search. Use the Edit scalable update group screen to enter the IP address and user credentials for one node in the iLO Federation group that HP SUM uses as the interface for inventory and deployment to the nodes in the group.

When you select a group, HP SUM displays information about the group, including a description, server types, number of servers, and installed firmware versions. HP SUM displays the PMC, CPLD, System ROM, and iLO firmware. HP SUM only deploys System ROM and iLO firmware to iLO Federation group nodes.

The HP SUM iLO Federation feature relies on proper configuration of iLO Federation groups before you launch HP SUM. Multiple iLO Federation groups with the same name or fragmented iLO Federation groups will result in HP SUM only working with a portion of the expected systems.
