Owner manual

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 ServerNet expansion board (MSEB)
A ServerNet expansion board (SEB) that uses plug-in cards (PICs) to provide a choice of
connection media for routing ServerNet packets.
module
A set of components sharing a common hardware interconnection, such as a backplane. A
module is a subset of a group and is usually contained in an enclosure. In NonStop
S-series servers, an enclosure contains one group, and a group contains only one module.
MSEB port
A connector on modular ServerNet expansion boards (MSEBs) used for ServerNet links.
An MSEB has four fixed serial-copper ports and six plug-in card (PIC) slots that accept a
variety of connection media. See also SEB port.
multifunction I/O board (MFIOB)
A ServerNet adapter that contains ServerNet addressable controllers (SACs) for SCSI
and Ethernet; a service processor; a router with ServerNet links to the processor, to the
two ServerNet adapter slots, and to one of the ServerNet expansion board (SEB) slots;
and connections to the serial maintenance bus (SMB), which connects components within
the enclosure to the service processor. The MFIOB is integrated into the I/O
multifunction (IOMF) CRU.
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.
