SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

object One or more of the devices, lines, processes, and files in a subsystem; any entity subject to
independent reference or control by one or more subsystems. In the Subsystem Control Facility
(SCF), each object has an object type and object name.
object name A unique name for an SCF object within a subsystem.
object type The category of Subsystem Control Facility (SCF) objects to which a specific SCF object belongs;
for example, a specific disk has the object type DISK and a specific terminal may have the object
type SU. Each subsystem has a set of object types for the objects it manages.
object-name
template.
A name that stands for more than one Subsystem Control Facility (SCF) object. Such a name
includes one or more wild-card characters, such as * (asterisk) and ? (question mark). See also
wild-card character.
operator message A message, intended for an operator, that describes a significant event on a HP NonStop S-series
system. An operator message is the displayed-text form of an Event Management Service (EMS)
event message. See also event message.
OSM Stands for HP Open System Management (OSM) Interface. Replaces TSM as the system
management tool of choice for NonStop servers. Provides the same functionality as TSM while
overcoming limitations of TSM. OSM is required for support of new functionality released in
G06.21 and later.
peripheral
enclosure
An enclosure that contains components related to one or more peripherals. The 519x tape
subsystem is an example of a peripheral enclosure. Peripheral enclosures are not part of the set
of system enclosures. Contrast with system enclosure.
Peripheral Utility
Program (PUP)
A utility used in D-series and earlier RVUs to manage disks and other peripheral devices. In
G-series RVUs, PUP functions are performed by the Subsystem Control Facility (SCF).
PIN See process identification number (PIN).
PMF 2 CRU See processor multifunction (PMF) 2 CRU.
PMF CRU See processor multifunction (PMF) CRU.
POOL object type The Subsystem Control Facility (SCF) object type for Storage Management Foundation (SMF)
storage pools. See also Storage Management Foundation (SMF).
primary path A path enabled as the preferred path. When a primary path is disabled, an alternate path
becomes the primary path. Contrast with alternate path.
primary processor The processor that is designated as owning the ServerNet addressable controller (SAC) connected
to separate processors running the HP NonStop operating system. The primary processor is the
processor that has direct control over the SAC. Contrast with backup processor.
process A program that has been submitted to the operating system for execution, or a program that is
currently running in the computer.
process ID A number that uniquely identifies a process. It consists of the processor (CPU) number and the
process identification number (PIN).
process
identification
number (PIN)
A number that uniquely identifies a process running in a processor. The same number can exist
in other processors in the same system. See also process ID.
processor 1. A functional unit of a computer that reads program instructions, moves data between processor
memory and the input/output controllers, and performs arithmetic operations. Processors are
sometimes referred to as central processing units (CPUs), but a HP NonStop system has multiple
cooperating processors rather than a single CPU.
2. One or more computer chips, typically mounted on a logic board, that are designed to perform
data processing or to manage a particular aspect of computer operations.
processor
enclosure
A HP NonStop S-series system enclosure containing exactly one group, which includes processors,
ServerNet adapters, disk drives, components related to the ServerNet fabrics, and components
related to electrical power and cooling for the enclosure.
processor
multifunction (PMF)
2 CRU
A HP NonStop S-series customer-replaceable unit (CRU) that contains a power supply, service
processor (SP), ServerNet router 2, Ethernet controller, three ServerNet addressable controllers
(SACs), and a processor and memory system in a single unit. The PMF 2 CRU consists of three
subassemblies: the processor and memory board (PMB), the multifunction I/O board (MFIOB),
and the power supply subassembly.
