a method for identifying the SCSI channel that
should be used to transmit commands. Most
programs, such as tape backup utilities, use ASPI.

ASR-2 Timer
A timer that is periodically reset when the system is
running.
Automatic
Revision Tracking
A feature of the Revision History Table that allows
you to review the configuration changes. The table
provides the server with hardware version
