status/console
message
A message that keeps the user informed about the status of the requested action.
subnetwork
A physical network within an internet protocol (IP) network. Each IP network can be divided into
a number of subnetworks. Within a given network, each subnetwork is treated as a separate
network. Outside that network, the subnetworks appear as part of a single network. The terms
subnetwork and subnet are used interchangeably.
subnetwork
address
An extension of the
addressing scheme that allows a site to use a single
for multiple physical networks. A subnetwork address is created by dividing the local
part of an IP address into a subnetwork number (identifying a particular subnetwork) and a host
number (uniquely identifying the host system within the subnetwork). The terms subnetwork and
subnet are used interchangeably.
Subsystem Control
Facility (SCF)
An interactive interface for configuring, controlling, and collecting information from its subsystems.
super group
The group of user IDs that have group number 255. This group has special privileges. Many
NonStop operating system utilities contain commands or functions that can be executed only by
a member of the super group.
super ID
A privileged user in the NonStop operating system environment who can read, write, execute,
and purge all files on the system. The super ID has the user ID 255,255.
synchronous
A mode of data communications transmission in which characters are accumulated in a buffer
at the sending terminal and then sent as a block of data. Synchronous transmission normally uses
external clocking provided by a synchronous modem. The clocking scheme assumes that once
transmission starts, characters arrive in a block at a predetermined speed. Contrast with
SYSnn subvolume
A subvolume on the $SYSTEM volume that contains a version of the NonStop operating system
image. The letters nn represent an octal number in the range %00 through %77. There might be
several SYSnn subvolumes, only one of which contains the current OSIMAGE.
system
All the processors, controllers, firmware, peripheral devices, software, and related components
that are directly connected together to form an entity that is managed by one NonStop operating
system image and operated as one computer.

system
configuration
database
The database file on the $SYSTEM.ZSYSCONF subvolume that contains configuration information
for objects in the subsystems that are configured by
, including the Kernel subsystem, the
storage subsystem, the ServerNetLan System Area (SLSA) subsystem, and the Wide Area Network
(WAN) subsystem.
system console
A PC-compatible workstation on which the OSM client software is running.
system error
A condition encountered by the
while performing a command or other operation that
causes the command or operation to fail.
system load
To start the system which loads the NonStop operating system image, typically from the OSIMAGE
file in the
of a specified disk volume into the memory of a halted processor.
All processors must be halted before you can perform a system load. To load the system, use the
system serial
number
A unique number assigned to a NonStop server when it is built. OSM uses the system serial
number for connections between the workstation and the server. The system serial number, typically
five or six alphanumeric characters, can be used for ordering and tracking purposes.
T
Tetra 16 topology
A
of NonStop S-series servers that allows a maximum of eight processor
enclosures (16 processors). The maximum number of I/O enclosures allowed by the Tetra 16
topology varies depending on the release version update (RVU) and the server model. Contrast
with
topology.
Tetra 8 topology
A
of NonStop S-series servers that allows a maximum of four processor
enclosures (eight processors) and eight I/O enclosures. Contrast with
topology.
