Integrated Lights-Out Technology
The iLO subsystem is a standard component of selected ProLiant servers that provides server
health and remote server manageability. The iLO subsystem includes an intelligent
microprocessor, secure memory, and a dedicated network interface. This design makes iLO
independent of the host server and its operating system. The iLO subsystem provides remote
access to any authorized network client, sends alerts, and provides other server management
functions.
Using iLO, you can:
Remotely power up, power down, or reboot the host server.
Send alerts from iLO regardless of the state of the host server.
Access advanced troubleshooting features through the iLO interface.
Diagnose iLO using HP SIM through a web browser and SNMP alerting.
For more information about iLO features, refer to the HP Integrated Lights-Out User Guide
on the Documentation CD or on the HP website (http://www.hp.com/servers/lights-out).
Automatic Server Recovery
ASR is a feature that causes the system to restart when a catastrophic operating system error
occurs, such as a blue screen, ABEND, or panic. A system fail-safe timer, the ASR timer,
starts when the System Management driver, also known as the Health Driver, is loaded.
When the operating system is functioning properly, the system periodically resets the timer.
However, when the operating system fails, the timer expires and restarts the server.
ASR increases server availability by restarting the server within a specified time after a
system hang or shutdown. At the same time, the HP SIM console notifies you by sending a
message to a designated pager number that ASR has restarted the system. You can disable
ASR from the HP SIM console or through RBSU.
HP Systems Insight Manager
HP SIM is a web-based application that allows system administrators to accomplish normal
administrative tasks from any remote location, using a web browser. HP SIM provides device
management capabilities that consolidate and integrate management data from HP and third-
party devices.
IMPORTANT: You must install and use HP SIM to benefit from the Pre-Failure Warranty for
processors, hard drives, and memory modules
