ServerNet LAN Systems Access (SLSA) subsystem
ServerNet LAN Systems Access (SLSA) subsystem. A subsystem of the HP NonStop
Kernel operating system for configuration and management of ServerNet local area
network (LAN) objects in G-series RVUs.
SERVERNET object type. In the Kernel subsystem, the object type for either the $ZSNET
ServerNet subsystem manager process or the ServerNet X fabric or Y fabric.
ServerNet wide area network (SWAN) concentrator. A HP data communications
peripheral that provides connectivity to a HP NonStop S-series server. The SWAN
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces.
service provider. (1) A person trained and qualified to service field-replaceable units
(FRUs). (2) An organization, such as the Global Customer Support Center (GCSC),
that helps you resolve problems with your HP NonStop™ S-series server. OSM and
TSM allow you to use the help of a service provider by configuring client software to
support remote notification and remote access.
SLSA subsystem. See ServerNet LAN Systems Access (SLSA) subsystem.
SPIFF (Software Problem Isolation and Fix Facility). A software identification tool whose
records are contained in the $SYSTEM.SYSnn.OSCONFIG file.
state. In SCF, one of the generally defined possible conditions of an object with respect to
the management of that object. Examples of states are DEFINED, STARTED, and
STOPPED.
storage subsystem. A subsystem of the HP NonStop Kernel operating system that handles
configuration and management of disk and tape devices in G-series RVUs.
storage subsystem manager process. The generic process that starts and manages disk
and tape drives. The $ZZSTO storage subsystem manager process is started and
managed by the $ZZKRN Kernel subsystem manager process through the $ZPM
persistence manager process.
subordinate objects. In Subsystem Control Facility (SCF), objects that are logically
subordinate to other objects. Some subsystems are structured hierarchically, with
objects of one type logically subordinate to (that is, controlled by) an object of another
type. For example, a number of subdevices can be configured on a single line. Some
SCF commands include a SUB option that refers to subordinate objects.
substate. Further information about the state of a device. The state and substate together
provide information about the current condition of a device or path to a device.
SUBSYS object type. The Subsystem Control Facility (SCF) object type for most
subsystems that use SCF as the user interface.
subsystem. (1) A secondary or subordinate system, usually capable of operating
independently of or asynchronously with a controlling system. (2) A program or set of
