3-52 Diagnostic Tools Configuring the Server for Automatic Server Recovery (ASR) When setting up the Server to use Automatic Server Recovery (ASR), you must set the ASR Timer, select the pager number to call, specify how you want the Server to recover from critical system faults, and specify when to monitor. This selection process is accomplished through the SmartStart installation process and can be modified through the Compaq System Configuration Utility. The ASR depends on an operating system driver that routinely notifies the ASR hardware that the system is operating properly. You should set the ASR Timer to allow the ASR to wait a reasonable period of time before resetting the system and activating the recovery process after a fault occurs. If the time between ASR notifications by the driver exceeds the specified time period, it will assume a fault has occurred and initiate the recovery process. For example, if the ASR Timer is set to 10 minutes, the system will not reset the Server unless 10 minutes elapses with no notification from the driver that the system is operating properly. You can select to be paged (modem required) and what mode the Server will be in when it restarts after a critical error. The following sections describe the different reboot options and the system requirements for each level. Unattended Recovery For unattended recovery, ASR will log the error information to the Critical Error Log, reset the Server, test all memory, automatically de-allocate any bad memory blocks found, page you (if modem is present and paging is selected), and attempt to reboot the operating system. Often the Server will restart successfully, making this the ideal choice for remote locations where trained service personnel are not immediately available. The ASR will only attempt the recovery process a limited number of times. If the Server continues to experience hardware/software errors and the number of recovery cycles exceeds the retry limit, the Server will log an error to the Critical Error Log and continue to boot the Compaq Utilities from the hard drive. The requirements to use this level of the ASR feature are: s Operating System with ASR support s ASR configured to load the operating system after reboot s Optional Hayes-compatible modem (only required for paging)

Diagnostic Tools
Configuring the Server for
Automatic Server Recovery (ASR)
When setting up the Server to use Automatic Server Recovery (ASR), you must set the
ASR Timer, select the pager number to call, specify how you want the Server to recover
from critical system faults, and specify when to monitor. This selection process is
accomplished through the SmartStart installation process and can be modified through the
Compaq System Configuration Utility.
The ASR depends on an operating system driver that routinely notifies the ASR hardware
that the system is operating properly. You should set the ASR Timer to allow the ASR to
wait a reasonable period of time before resetting the system and activating the recovery
process after a fault occurs. If the time between ASR notifications by the driver exceeds the
specified time period, it will assume a fault has occurred and initiate the recovery process.
For example, if the ASR Timer is set to 10 minutes, the system will not reset the Server
unless 10 minutes elapses with no notification from the driver that the system is operating
properly.
You can select to be paged (modem required) and what mode the Server will be in when it
restarts after a critical error. The following sections describe the different reboot options
and the system requirements for each level.
Unattended Recovery
For unattended recovery, ASR will log the error information to the Critical Error Log, reset
the Server, test all memory, automatically de-allocate any bad memory blocks found, page
you (if modem is present and paging is selected), and attempt to reboot the operating
system. Often the Server will restart successfully, making this the ideal choice for remote
locations where trained service personnel are not immediately available.
The ASR will only attempt the recovery process a limited number of times. If the Server
continues to experience hardware/software errors and the number of recovery cycles
exceeds the retry limit, the Server will log an error to the Critical Error Log and continue to
boot the Compaq Utilities from the hard drive.
The requirements to use this level of the ASR feature are:
Operating System with ASR support
ASR configured to load the operating system after reboot
Optional Hayes-compatible modem (only required for paging)
