The following ASR-2 flow chart shows you the sequence of events after a hardware or software error occurs:

Hardware/Software error occurs

Error records in the Critical Error Log, or the Integrated Management Log, depending on your server configuration.

Operating System halts normal

operation

ASR Timer expires

Server is reset

If a modem is installed and paging

is enabled, the Server Failure Notification pager alert is sent to the Server Administrator

Unattended server boots the

Operating System

If the server continues experiencing hardware/software errors and the number of ASR cycles exceed the specified number of recovery attempts, the server will log an error to the Server Health Log or the Integrated Management Log and boot the Compaq Utilities from the system partition on the hard drive
