maintenance entity
maintenance entity. A processing entity in a single HP NonStop™ system that collects
state information, environmental information, and failure data about the system
resource or resources for which the maintenance entity is responsible. A maintenance
entity can include both physical and software components, and a system can contain
multiple maintenance entities. For example, each I/O adapter module (IOAM) has its
own maintenance entity.
Maintenance Interface. See Archive and Database Maintenance Interface.
maintenance switch. The Ethernet switch that links the maintenance entities in various
modular components to the HP NonStop™ Open System Management (OSM)
Interface.
management process. A process through which an application issues commands to a
subsystem. A management process can be part of a subsystem, or it can be
associated with more than one subsystem. In the latter case, the management process
is logically part of each subsystem. Subsystem Control Point (SCP) is the management
process for all subsystems controlled by Subsystem Control Facility (SCF).
manager. (1) For an HP NonStop™ system, the person responsible for day-to-day
monitoring and maintenance tasks associated with a software subsystem on an
Expand node. (2) For a UNIX system, any person in Management and Information
Services management for the site.
man page. A term sometimes used in UNIX documentation for the online or hard-copy
version of a file that provides reference information. See reference page
.
master. The processor providing the results to a computation, which are externalized by a
processor board.
master service processor (MSP). A service processor (SP) in HP NonStop™ S-series
servers that provides the basic service processor functions as well as centralized
system functions such as a console port, a modem port for remote support functions,
and system-load control. The enclosure containing processors 0 and 1 (group 01) also
contains a pair of MSPs. See also expansion service processor (ESP)
.
MB. See megabyte (MB).
MCA. Maintenance console entity.
ME. See maintenance entity.
Measure. A tool used for monitoring the performance of HP NonStop™ servers. Measure
can be used to check the performance of a ServerNet cluster.
media access control (MAC) address. A value in the Medium Access Control sublayer of
the IEEE/ISO/ANSI local area network (LAN) architecture that uniquely identifies an
individual station implementing a single point of physical attachment to a LAN.
