Compaq ProLiant Server NMI Crash Dump Feature

Compaq Automatic Server Recovery (ASR)

ASR provides a means to recover from a lockup caused by either the software or the hardware.
The feature consists of a hardware countdown timer and a software driver, which periodically
refreshes the countdown timer. If the driver fails to report in and refresh the timer, the ASR
hardware timer normally resets the machine.

When configured for NMI Crash Dump, in Windows NT 4.0, Windows 2000, SCO OpenServer 5
and SCO UnixWare 7 ASR initiates the NMI Crash Dump instead of resetting the machine

ASR does not cover cases where the operating system or applications may be executing in an
indeterminate state. These cases would require the system administrator to intervene and initiate
the NMI with the crash dump button.

Note:

  All Compaq systems require the Compaq health (systems management) driver to support

ASR.
