Event Viewer Server Manager
Event Viewer Server Manager. A persistent process that routes messages and data
between the OSM Event Viewer on the system console and event server and summary
server processes on the HP NonStop™ server. An event server process retrieves
events. A summary server is a persistent process that maintains a summary of all the
events in a specified log file.
Expand network. The HP NonStop Kernel operating system network that extends the
concept of fault-tolerant operation to networks of geographically distributed HP Integrity
NonStop NS-series servers. If the network is properly designed, communication paths
are constantly available even if there is a single line failure or component failure.
Fibre Channel ServerNet adapter (FCSA). A ServerNet adapter that transmits data
between an HP NonStop™ server and Fibre Channel storage devices. This ServerNet
adapter is installed in an IOAM enclosure.
Fibre Channel switch (FC switch). Networking hardware that can connect an Enterprise
Storage System and an HP NonStop™ server. This switch allows any-to-any
connectivity.
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts (the
disk name and the file name); for example, B:MYFILE.
In the Guardian environment, disk file names include an Expand node name, volume
name, subvolume name, and file identifier; for example,
\NODE.$DISK.SUBVOL.MYFILE.
In the Open System Services (OSS) environment, a file is identified by a pathname for
example, /usr/john/workfile.
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).
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.
Gigabit Ethernet 4-port ServerNet adapter (G4SA). A multiport ServerNet adapter that
provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™
systems and Ethernet LANs. The G4SA is installed in slots 1, 2, 3, 4, and 5 of an I/O
adapter module (IOAM). There are two IOAMs in an I/O adapter module, so a total of
10 G4SAs can be installed in an enclosure. The G4SA is the only LAN adapter
supported for the IOAM enclosure. Although the G4SA implements the Ethernet 4
ServerNet adapter (E4SA) and the Fast Ethernet ServerNet adapter (FESA) functions,
it cannot be installed in an HP NonStop™ S-series enclosure.
HP 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
