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.
ROMPaq Utility
NOTE: For ROMPaq procedures, use a diskette or USB drive key, when applicable.
Flash ROM enables you to upgrade the firmware (BIOS) with system or option ROMPaq utilities. To
upgrade the BIOS, insert a ROMPaq diskette into the diskette drive and boot the system.
The ROMPaq utility checks the system and provides a choice (if more than one exists) of available ROM
revisions. This procedure is the same for both system and option ROMPaq utilities.
For more information about the ROMPaq utility, refer to the HP website
(http://www.hp.com/servers/manage

Integrated Lights-Out Manager 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 iLO documentation on the Documentation CD or on
the HP website (http://www.hp.com/servers/lights-out
).
Erase Utility
CAUTION: Perform a backup before running the System Erase Utility. The utility sets the system to its
original factory state, deletes the current hardware configuration information, including array setup and disk
partitioning, and erases all connected hard drives completely. Refer to the instructions for using this utility.
Run the Erase Utility if you need to erase the system for the following reasons:
• You want to install a new operating system on a server with an existing operating system.
• You want to change the operating system selection.
