configured object
configured object. A Subsystem Control Facility (SCF) object that exists at the time a
subsystem completes its initialization process, or an SCF object that is brought into
existence by a command issued through a subsystem management interface.
connection. (1) The path between two protocol modules that provides reliable stream
delivery service. (2) For OSM software, the logical link established between the client
software on a workstation and the server software on an HP NonStop™ S-series
system after a logon sequence has been performed. Two types of logical connections
are service connections and low-level links.
control and inquiry. The aspects of Subsystem Control Facility (SCF) object management
related to the state or configuration of an object. Such aspects include actions that
affect the state or configuration of an object, inquiries about the object, and commands
pertaining to the session environment (for example, commands that set default values
for the session).
CRU. See customer-replaceable unit (CRU).
current configuration file. See configuration file.
customer-replaceable unit (CRU). A unit that can be replaced in the field either by
customers or by qualified personnel trained by HP. CRUs are divided into the
categories of Class 1, Class 2, and Class 3 according to the risk of causing a system
outage if the documented replacement procedure is not followed correctly and how
much CRU-replacement training or experience is advisable. See also Class-1 CRU
Class-2 CRU, Class-3 CRU, and field-replaceable unit (FRU)
DIH. See Driver Interrupt Handler.
Distributed Systems Management (DSM). A set of tools used to manage HP NonStop™
systems and Expand networks.
Distributed Systems Management/Software Configuration Manager (DSM/SCM). A
graphical user interface (GUI)-based program that installs new software and creates a
new NonStop OS. DSM/SCM creates a new software revision and activates the new
software on the target system.
Driver Interrupt Handler. The driver interrupt handler provides an interface to the LAN for
all client processes that want to write to or read from the LAN. The driver is a set that
client processes call to set up access to, send data to, and enable receipt of data from
the LAN. The interrupt handler routes incoming packets to specific inbound queues for
the appropriate client processes.
DSM. See Distributed Systems Management (DSM)
.
DSM/SCM. See Distributed Systems Management/Software Configuration Manager
(DSM/SCM).
EMS. See Event Management Service (EMS).
