Installation Manual

Server signatures (Synergy compute modules only)
When HPE OneView manages a Synergy compute module, iLO generates a server signature
that allows HPE OneView to manage unique network settings, virtual identifiers, and adapter
settings.
The server signature is refreshed and verified for compliance each time iLO starts. It includes
information such as the frame bay and UUID, the HPE OneView domain IP address, and the
server device signatures.
If the server is moved to a different frame or bay, or its hardware configuration changes upon
insertion into a bay, the server signature changes. When this change occurs, the settings
configured by HPE OneView are cleared, an event is logged in the iLO event log, and a iLO
RESTful API event is generated. This process prevents duplicate addresses and helps HPE
OneView ensure that the server has a unique profile.
In most cases, HPE OneView automatically rediscovers and configures the server. If this discovery
and configuration does not occur, use the HPE OneView software to refresh the frame that
contains the server.
The server signature data cannot be viewed or edited in the iLO web interface, but it can be read
with a REST client. For more information, see http://www.hpe.com/info/restfulinterface/docs.
Using iLO with HPE SIM
The iLO firmware is integrated with HPE SIM in key operating environments, providing a single
management console from a standard web browser. While the operating system is running, you
can establish a connection to iLO by using HPE SIM.
Integration with HPE SIM provides the following:
• Support for SNMP trap delivery to an HPE SIM console—The HPE SIM console can be
configured to forward SNMP traps to a pager or email address.
• Support for management processors—All iLO devices installed in servers on the network
are discovered in HPE SIM as management processors.
• Grouping of iLO management processors—All iLO devices can be grouped logically and
displayed on one page.
• HPE Management Agents or Agentless Management—iLO, combined with Agentless
Management or the HPE Management Agents, provides remote access to system
management information through the iLO web interface.
• Support for SNMP management—HPE SIM can access Insight Management Agent
information through iLO.
HPE SIM features
HPE SIM enables you to do the following:
• Identify iLO processors.
• Create an association between an iLO processor and its server.
• Create links between an iLO processor and its server.
• View iLO and server information and status.
• Control the amount of information displayed for iLO.
The following sections summarize these features. For detailed information, see the HPE SIM
user guide.
Establishing SSO with HPE SIM
1. Configure iLO for HPE SIM SSO and add HPE SIM trusted servers.
