HP ProLiant DL360 Generation 4 Server Maintenance and Service Guide
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 Integrated Lights-Out User
Guide on the Documentation CD or on the HP website

).
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.
