service processor (SP)
service processor (SP). A physical component of the processor multifunction (PMF)
customer-replaceable unit (CRU) or I/O multifunction (IOMF) CRU that controls
environmental and maintenance functions (including system load functions) in the
enclosure. SPs operate in pairs to provide fault tolerance. The two SPs in group 01
are designated the master service processors (MSPs). Other pairs of SPs within a
system are called expansion service processors (ESPs). See also expansion service
processor (ESP) and master service processor (MSP).
service processor (SP) event message. A type of notification. SP event messages are
generated by the master service processors (MSPs) on the HP NonStop™ S-series
server. The Compaq TSM Notification Director Application can gather SP event
messages directly from the MSPs, allowing SP event messages to be received when
the HP NonStop Kernel operating system is not running. The System Down Message
is a special type of SP event message.
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. The Compaq
TSM package allows you to use the help of a service provider by configuring TSM to
support remote notification and remote access.
service side. The side of a system enclosure that contains, behind an optional door,
processor multifunction (PMF) customer-replaceable units (CRUs) or I/O multifunction
(IOMF) CRUs, ServerNet expansion boards (SEBs), modular SEBs (MSEBs), and
ServerNet adapters; it is opposite the appearance side
. Cables are accessed from the
service side. System enclosures are typically arranged so that the service side is the
least visible side.
session. In the Open System Services (OSS) environment, a set of process groups
associated for job control purposes. A session can have a controlling terminal.
session leader. In the Open System Services (OSS) environment, the process that created
a session.
session lifetime. In the Open System Services (OSS) environment, the period that begins
when a session is created and ends when the lifetime of the last remaining process
group of the session ends.
setup configuration. A simple stand-alone network used to configure the Compaq TSM
environment. The setup configuration consists of the server, the primary system
console, an Ethernet hub, and two local area network (LAN) cables. One cable
connects the primary system console to the hub, and another cable connects the hub
to a processor multifunction (PMF) customer-replaceable unit (CRU) in group 01 of the
server. When TSM configuration is complete, the setup configuration can serve as the
working network configuration. Variations of the setup configuration can be constructed
using additional cables and hubs to increase fault tolerance.
