and system-load control. The OSM system console communicates directly with the MSPs on the
server. The
enclosure containing processors 0 and 1 contains the MSP pair.
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.
Media Interface
Connector (MIC) A type of head on a fiber-optic cable that has locking wings on the sides.
memory dump The contents of a processor's memory copied onto disk or magnetic tape for later analysis, as
produced in a tape dump operation. You should submit the memory dump to your service provider.
microcode Any machine code or data that can run in a microprocessor. HP produces two types of microcode
for NonStop systems: volatile and nonvolatile. Volatile microcode is loaded into the volatile
random-access memory (RAM) of some types of printed wiring assemblies (PWAs) and is not
retained in a host PWA when power to the PWA is interrupted. For nonvolatile microcode, see
firmware .
See also millicode .
millicode RISC instructions that implement various TNS low-level functions such as exception handling,
real-time translation routines, and library routines that implement the TNS instruction set. Millicode
is functionally equivalent to TNS
microcode .
mirrored disk or
volume A pair of identical disk drives that are used together as a single logical volume. One drive is
considered primary and the other is called the mirror. Each byte of data written to the primary
drive is also written to the mirror drive. If the primary drive fails, the mirror drive can continue
operations. Each drive has the same volume name, but the name has a suffix to show which drive
is the primary (-P) and which is the mirror (-M).

modular cabinet A cabinet with an integrated standard 19-inch rack equipped with a power distribution unit (PDU),
doors, slides, brackets, castors, leveling pads, and optional side panels.
module Part of the group, module, slot naming convention for uniquely identifying the logical location of
a component within a system. A module is a subset of a
group , and it is usually contained in an
enclosure. A module contains one or more slots. A module can consist of components sharing
common interconnect, such as a backplane, or it can be a logical grouping of components
performing a particular function.
multilane link A communication link between HP NonStop Cluster Switches that can consist of multiple ServerNet
cables. Two-lane links and four-lane links are examples of multilane links.
multimode
fiber-optic (MMF)
ServerNet cable A fiber-optic cable that either allows more than one mode to propagate or supports propagation
of more than one mode of a given wavelength. MMF ServerNet cable typically supports shorter
transmission distances than
single-mode fiber-optic (SMF) ServerNet cable .
N
name For the OSM software, the name attribute is determined by the connection type. When you use
the service connection, the
logical name is used. When you use the low-level link, the service
processor (SP) logical name is used.
Examples of logical names:
• $DATA04-P is the logical name of the disk CRU located in group 1, module 1, slot 13.
• IOMF2.SCSI-3.GRP-1.MOD-1.SLOT-50 is the logical name of the third SCSI bus on the
IOMF2 CRU located in group 1, module 1, slot 50.
Examples of service processor (SP) logical names:
• SCSICRU.GRP-1.MOD-1.SLOT-3 is the SP logical name of the disk CRU located in group 1,
module 1, slot 3.
• PMF.SCSI-3.GRP-1.MOD-1.SLOT-50 is the SP logical name of the third SCSI bus on the PMF
CRU located in group 1, module 1, slot 50.
neighbor check A check performed between processor switch and the millicode before enabling the ServerNet
connection.
