Integrated Management Log
The IML records hundreds of events and stores them in an easy-to-view form. The IML timestamps each event
with 1-minute granularity.
You can view recorded events in the IML in several ways, including the following:
• From within HP SIM
• From within operating system-specific IML viewers
o For Windows: IML Viewer
o For Linux: IML Viewer Application
• From within the iLO user interface
• From within HP Insight Diagnostics (on page 60)
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
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.
