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 (does not apply to HP ProLiant DL980 Servers), 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. 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 System Management Homepage or through RBSU.

USB support

HP provides both standard USB 2.0 support and legacy USB 2.0 support. Standard support is provided by

the OS through the appropriate USB device drivers. Before the OS loads, HP provides support for USB

devices through legacy USB support, which is enabled by default in the system ROM.

Legacy USB support provides USB functionality in environments where USB support is not available normally.

Specifically, HP provides legacy USB functionality for the following:

• POST

• RBSU

• Diagnostics

• DOS

• Operating environments which do not provide native USB support

Redundant ROM support

The workstation blade enables you to upgrade or configure the ROM safely with redundant ROM support.

The workstation blade has a single ROM that acts as two separate ROM images. In the standard

implementation, one side of the ROM contains the current ROM program version, while the other side of the

ROM contains a backup version.

NOTE: The server ships with the same version programmed on each side of the ROM.

Safety and security benefits

When you flash the system ROM, ROMPaq writes over the backup ROM and saves the current ROM as a

backup, enabling you to switch easily to the alternate ROM version if the new ROM becomes corrupted for

any reason. This feature protects the existing ROM version, even if you experience a power failure while

flashing the ROM.
