group list
group list. An Open System Services (OSS) process attribute that is used with the effective
group ID of the process to determine the file access permissions for the process.
GRT. See Guided Replacement Toolkit (GRT).
Guardian. An environment available for interactive or programmatic use with the HP
NonStop™ operating system. Processes that run in the Guardian environment usually
use the Guardian system procedure calls as their application program interface.
Interactive users of the Guardian environment usually use the HP Tandem Advanced
Command Language (TACL) or another HP product’s command interpreter. Contrast
with Open System Services (OSS).
Guardian environment. The Guardian application program interface (API), tools, and
utilities.
Guardian services. An application program interface (API) to the HP NonStop™ operating
system, plus the tools and utilities associated with that API. This term is synonymous
with Guardian environment. See also Guardian.
Guardian user ID. See HP NonStop™ operating system user ID.
GUI. See graphical user interface (GUI).
GUID. See globally unique ID (GUID).
guided procedure. A software tool that assists you in performing complex configuration or
replacement tasks on an HP NonStop™ server. OSM guided procedures are launched
through actions in the OSM Service Connection. TSM guided procedures are
accessible from the Start menu on your system console. Guided procedures include
Replace PMF, IOMF, SNDA, SEB, or MSEB. Some names vary between OSM and
TSM. For example, Add Node to ServerNet Cluster is the OSM equivalent of Configure
ServerNet Node in TSM.
Guided Replacement Toolkit (GRT). A software product that guides you through online
replacement of these customer-replaceable units (CRUs) on HP NonStop™ S-series
systems: I/O multifunction (IOMF) CRUs, power supplies, processor multifunction
(PMF) CRUs, and 6760 ServerNet device adapters. GRT is used only with older
versions of TSM server software. If you are replacing a CRU in a system running TSM
server version T7945AAX (shipped with G06.13) or later, use the appropriate guided
procedure.
hard link. In the Open System Services (OSS) file system, the relationship between two
directory entries for the same file. A hard link acts as an additional pointer to a file. A
hard link cannot be used to point to a file in another fileset. Contrast with symbolic link.
hard reset. An action performed on an HP NonStop™ Cluster Switch (model 6770) and HP
NonStop™ ServerNet Switch (model 6780) that reinitializes the router-2 ASIC within
the switch, disrupting the routing of ServerNet messages through the switch for several
minutes. When the hard reset is finished, the paths are restored automatically.
