NonStop System Glossary

blocked signal
A programmatic signal that is currently in the pending signal mask of a process and, when
generated, is not delivered to the process because of the signal mask setting. Some signals cannot
be blocked.
bond
A reliable connection that ensures the required electrical conductivity between conductive parts
that must be electrically connected.
bonded
The mechanical interconnection of conductive parts to maintain a common electrical potential.
bonding
The permanent joining of conductive parts to form a path that ensures electrical continuity and the
capacity to safely conduct any current likely to be imposed.
bonded interface
An interface created to combine two or more physical interfaces for fault tolerance, bandwidth
aggregation, or both.
bonding jumper
See main bonding jumper.
boot
A synonym for load. Load is the preferred term in this and other publications for NonStop servers.
BOOTP
A protocol for providing initialization information to diskless nodes in an open network. On NonStop
BladeSystems, BOOTP is used to retrieve the HSS firmware that enables the system to load its
processors.
BOOTP client (BOOTPC)
A client provided as a Portable Silicon Operating System (pSOS) system product task in the essential
firmware on each communications line interface processor (CLIP) in the ServerNet wide area
network (SWAN) concentrator. BOOTPC tasks are also provided on the host system as the
WANBoot process in the WAN subsystem.
BOOTP daemon (BOOTPD)
The BOOTP server. One BOOTPD runs as a Portable Silicon Operating System (pSOS) system
product task in the essential firmware on each communications line interface processor (CLIP) in
the ServerNet wide area network (SWAN) concentrator. BOOTPD tasks are also provided on the
host system as the WANBoot process in the WAN subsystem.
