NonStop System Glossary

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 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

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 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 a

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 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.

halted-state services (HSS)

A millicode module that provides a maintenance interface when a processor is in the stopped state.

HSS is sometimes called boot millicode.
