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 Kernel 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 Kernel 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
asynchronous .
SYSnn subvolume
A subvolume on the $SYSTEM volume that contains a version of the NonStop Kernel
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
HP NonStop Kernel operating system image and operated as one computer.
See also server and node .
system configuration database
The database file on the $SYSTEM.ZSYSCONF subvolume that contains configuration
information for objects in the subsystems that are configured by
SCF , including the
Kernel subsystem, the storage subsystem, the ServerNetLan System Area (SLSA)
subsystem, and the Wide Area Network (WAN) subsystem.
See also configuration file.
system console
A PC-compatible workstation on which the OSM client software is running.
