fault tolerance
fault tolerance. The ability of a NonStop S-series system to continue processing despite
the failure of any single software or hardware component within the system.
firmware. Code in memory that is necessary for the power-up initialization and
communication with a host or device. The software for components of the ServerNet
architecture (for example, an adapter) is called firmware. Some firmware for ServerNet
components is downloaded when the system or component is loaded.
fixed process configuration. Using Subsystem Control Facility (SCF) to configure a
generic process to always start in the first available processor (that is, to be fault
tolerant).
flash memory. A type of memory that contains essential firmware and nonessential
firmware.
flash PROM. A type of programmable read-only memory (PROM) that is electrically
reprogrammable.
generic process. A process created and managed by the Kernel subsystem. Also known
as a system-managed process. A common characteristic of a generic process is
persistence. See also persistence.
Global Customer Support Center (GCSC). A support organization that provides telephone
and remote diagnostic support for HP customers. There are GCSCs located all over
the world. See also Online Support Center (OSC).
HP Tandem Advanced Command Language (TACL). The user interface to the HP
NonStop Kernel operating system. The TACL product is both a command interpreter
and a command language. Users can write TACL programs that perform complex
tasks simply or provide a consistent user interface across independently programmed
applications.
input/output process (IOP). A running program (part of the operating system) that
manages the I/O functions for one or more ServerNet addressable controllers (SACs)
of the same type.
input source. The resource from which Subsystem Control Facility (SCF) accepts
command input. SCF can accept input from a terminal or a disk file. The initial input
source is determined by the form of the RUN command used to initiate SCF. At any
time during an SCF session, the input source can be temporarily changed to execute a
series of commands from a command file.
interim product modification (IPM). The HP method of releasing incremental software
updates. An IPM can include one or more corrections to HP code or it can contain
code that adds new function to a NonStop software product. See input/output process
(IOP).
IP address. An address that identifies a specific host to the Internet protocol (IP). An IP
address consists of two parts: a network address, which identifies the network, and a
