attribute. (1) For the Subsystem Control Facility (SCF), a characteristic of an entity. For
example, two attributes of a process might be its program file and its user ID. An
attribute is sometimes called a modifier. (2) For the Compaq Tandem Service
Management (TSM) package, a data item associated with a resource. All attributes can
be viewed and some can be modified.
backup processor. A processor in the Compaq NonStop™ Kernel operating system that
communicates with the primary processor, allowing the processors to remain
independent. A component failure in one processor has no effect on any other processor.

Compaq Tandem Service Management (TSM) package. A software product for
NonStop™ Himalaya S-series servers that provides the information needed to perform
functions such as querying resources and testing, provides notification of problems on
the system, and allows local or remote access to the system for service and maintenance.
TSM performs the same role as that of Tandem Maintenance and Diagnostic System
(TMDS), Syshealth, and Remote Maintenance Interface (RMI) on earlier systems.
CRU. See customer-replaceable unit (CRU)
.
customer-replaceable unit (CRU). A subset of field-replaceable units (FRUs) that can be
installed and serviced (replaced) by customers, without using special tools or special
Compaq training. CRUs can be replaced while the system is running.
Event Management Service (EMS). A part of the Distributed System Management (DSM)
package used to provide event collection, event logging, and event distribution facilities.
It provides different event descriptions for interactive and programmatic interfaces, lets
an operator or an application select specific event-message data, and allows for flexible
distribution of event messages within a system or a network. EMS has a Subsystem
